Describe the scope of work in detail. Please include a summary of key deliverables.
Creation of ERC-20 Smart Contract on Solana for VRD native token deployment:
As a developer, I need to create ERC-20 smart contract so it can be used to purchase pCRBN NFTs later.
Bridge integration [nice to have]:
As a user, I want to be able to convert my VRD (Eth) to VRD (Solana) so I can buy/rent pCRBN.
(Is this solved by having a VRD/SOL liquidity pool and VRD/ETH liquidity pool, hence arbitrage will keep the prices similar?)
Maybe an API to rocketxchange would make this easier?
Creation of ERC-721 Smart Contracts:
As a developer, I need to create ERC-721 smart contracts with partial ownership capabilities so that we can tokenize tangible carbon offsetting assets into pCRBN NFTs.
Minting pCRBN NFTs:
As a company, VRD needs to mint pCRBN NFTs to let users rent/buy.
We should have sole authority over minting of pCRBN NFTs.
Metadata for pCRBN NFTs:
As a user, I want metadata associated with each pCRBN NFT so that I can verify the environmental impact and origin of the carbon project. I want to be able to name my land when rented or bought.
I want to be able to see the layout of my land on the map.
See for inspiration: https://ecotree.green/en/companies/csr
Purchasing pCRBN NFTs [is not too urgent]:
As a user, I want to purchase pCRBN NFTs using ETH so that I can own a portion of a carbon offset project permanently.
Renting pCRBN NFTs:
As a user, I want to rent pCRBN NFTs using $VRD so that I can temporarily contribute to carbon offset projects and gain access to staking rewards. After the temporary period, the NFTs come back to deployer wallet or are available for repurchase. The user is also able extend the rental period before the existing period expires.
Staking pCRBN NFTs:
As a user, I want to stake my $VRD from the same wallet that contains the pCRBN NFTs to earn staking rewards in $VRD. There is a limit on the number of $VRD that can be staked from each wallet. Wallets without pCRBN can stake any amount of $VRD for a small APY in each of the pools with different locking times. The rewards from each pool will be given daily and the user has an option to restake the rewards for the same fixed period starting that day.
As a developer, I need to implement a staking mechanism with variable APY returns for various pools (e.g Paal staking tool) (100%-200%) so that we can incentivize users to participate in the platform. The staking mechanism should also show the total $VRD that will be distributed to the wallet immediately after staking and the rewards should be disbursed incrementally over the locked period.
For example: joe has 1 pCRBN so he is eligible for the 3 staking pools with 10%, 20%, and 30% APY for 10, 20, and 30 days locked respectively. If joe selects the 2nd pool with 10 VRD, then the wallet shows 12 VRD - the 2 VRD comes from 20% APY.
The dashboard shows 10.1096VRD for the first 20 days and disburse incrementally for a total of .1096 VRD in 20 days. After, 20 days. The user gets downgraded to the basic APY that everyone is eligible for. Since the rewards are provided daily, joe has the option to press the restake button that automatically restakes the daily rewards of .0055 in this example for 20 days each for the same 20% APY.
User-Friendly Dashboard [we have a designers and frontend dev, would like cost from you though]
As a user, I want a user-friendly dashboard where I can manage my pCRBN NFTs, view my staking rewards, and track the environmental impact of my contributions.

We contacted Interexy to get help with CI/CD implementation, including test automation, in our app team, help with creating a more modular approach to make it easier to reuse componets across many apps, and for help with validating our technology choices for our app development (WASM, Flutter, native, other).

Ensure solid understanding of CI/CD in team
Demonstrate CI/CD pipecleaner flow
Hands-on based result for aiding technology choices for app
Modular architecture for new app dev paradigm
We did not get what we hoped for, in terms of understanding and implementation of CI/CD. We also did not get the tech help to the tech valuation (e.g. WASM test and hw app debugging - this was carried out by our own engineers).
Describe their project management. Did they deliver items on time? How did they respond to your needs?
Our PM has been reacting to all needs and have tried her best to keep up with what we wanted. We are hard to work with, as we have a deep understanding of tech, and also of what CI/CD is and is not. It is clear that Interexy is very adapt at working with Agile (SCRUM and likely SAFE), and less used to work with CI/CD.
Further, we do not care so much about detailed process and architecture documentation, which counters how many more traditional companies would approach app dev. So - our very nice, professional, and structured PM, has had a hard time, as what we are after is outside the usual comfort zone.

Are there any areas for improvement or something Interexy could have done differently?
Yes. Hire people with very deep tech knowhow (system engineers/hw engineers). Also, when venturing into a new setup with a customer, make sure that the requirements are well understood and within the domain of what can be delivered on (e.g. CI/CD seemed to be a new concept and so did troubleshooting on the hw level).

What were the measurable outcomes from the project that demonstrate progress or success?
We are approaching the official launch of the product to consumers and have been able to achieve this with an end-to-end timeline of ~8 months. Considering that we are developing a B2C product, that is an impressive timeline. Here are some specific, measurable outcomes:
On-time delivery: The vendor consistently met sprint commitments and delivered most planned features on schedule. They maintained a 80%+ on-time delivery rate across 16+ sprints, ensuring the project stayed on track.
Feature completion: All critical features in the backlog were successfully developed and tested, including: User onboarding flow with AI/chat interaction Financial account linking with support for 15,000 institutions via multiple financial aggregators
Transaction aggregation, search, and filtering with real-time updates and <100ms response times
Automated budgeting with customizable rules and categorization, handling over 50 unique categories
Capital advance loan origination with automated principal payments to creditors and loan payback tracking
Code quality: The codebase maintained a high standard of quality, ensuring the product is reliable and maintainable.
The team consistently followed best practices such as SOLID principles and design patterns.
Performance optimization: The vendor was able to design a scalable serverless backend architecture that has been purpose built to scale with growth.
Agile velocity: The team demonstrated a consistent velocity of 40 story points per 2-week sprint, allowing us to accurately predict and plan for future releases. They maintained this velocity while ensuring high quality and technical excellence.
Technical debt management: The team proactively identified and resolved technical debt, keeping it below 10% of the overall project effort. This ensures the codebase remains clean, efficient, and easy to maintain.
Continuous integration and deployment: The vendor set up a robust CI/CD pipeline that automated the build, test, and deployment process. This reduced manual effort and allowed for faster iterations and shorter feedback loops.
Knowledge transfer and documentation: The vendor maintained comprehensive documentation, including architecture diagrams, API specifications, and user guides as needed.

Describe the scope of work in detail. Please include a summary of key deliverables.
We were looking for a company who could take our idea and turn it to reality. We needed a platform for university graduates to be able to come and easily verify and tokenize their educational credentials.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
We have just wrapped up our build sprints with Interexy and are already receiving healthy traction. Universities have a demand and immyoutable is supplying a quality product.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
Interexy did really well with planning for a project with a lot of uncertainty. Some sprints took additional days, but they never under-delivered on those sprints. The task was always completed. Along the process we changed, edited, and even eliminated features. They are very familiar with how to handle ever changing startups.
What did you find most impressive or unique about this company?
The first thought that comes to mind is how Interexy can bring any idea to fruition. No task was too complex or challenging for their team.
Are there any areas for improvement or something Interexy could have done differently?
If you are a bootstrapped startup, I suggest adding in extra budgeting for app development. It is not something that is specifically Interexy's fault, but we did go over budget. App development comes at a hefty price tag, so be ready to pay a premium.

Interexy provides a mobile development resource that works on an SQL database company’s product using React Native, GraphQL, and REST APIs. They also provide a UI/UX designer who uses Figma.
Interexy’s resources have positively impacted the client’s work and integrated seamlessly with the internal team, and their technical capabilities are great. The team is responsive, communicative, and excels at taking feedback. Their high-quality resources and cost-effectiveness stand out.
A Clutch analyst personally interviewed this
client over the phone. Below is an edited
transcript.
BACKGROUND
Introduce your business and what you do there.
I work at Crate.io as a lead engineer for one of the company’s three products. My role involves leading the technical team for this product.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Interexy?
We needed more development power on our mobile app.
SOLUTION
What was the scope of their involvement?
Interexy provides us with staff augmentation. They’ve provided a mobile app developer who has integrated with our internal development team. The developer has inherited the codebase from our existing mobile app and developed more features. They work with React Native for the framework and also use GraphQL and REST APIs.
More recently, Interexy has also provided a UI/UX designer. We’ve given them guidelines for how we need them to work and our expectations. They work with Figma.
What is the team composition?
I mostly work with three teammates: a mobile app developer, a UI/UX designer, and an account manager. Additionally, someone from Interexy’s higher management is involved, though we only interact with them if necessary.
How did you come to work with Interexy?
When I joined the team, we already had an ongoing collaboration with Interexy, so I wasn’t involved in the early steps of the engagement.
How much have you invested with them?
We spent €6,000 (approximately $6,400 USD) per month when we only had the developer, and we’ve spent €9,000–€10,000 (approximately $9,700–$11,000 USD) per month since we onboarded the UI/UX designer. In total, we’ve spent €60,000–€70,000 (approximately $64,000–$75,000 USD) with Interexy.
What is the status of this engagement?
We started working with the mobile app developer in May 2022 and with the UI/UX designer in November 2022. Our engagement with Interexy is ongoing.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
Interexy's resources are tightly integrated with our team, and they've had a very good impact. The developer has worked very well with us; he's very responsive and communicative and quickly got up to speed. Moreover, he's capable from a technical perspective. Our internal developers work remotely, and when we planned a social event, they asked if the Interexy developer could join us because they feel he's part of the team.
As for UI/UX design, our interface has a visual difference, though Interexy's impact isn't easy to quantify. Still, I was surprised by how quickly they could provide a good candidate matching our specialized needs. The onboarding process was very smooth, with support from their side.
Since I took over the collaboration with Interexy, their communication and support have been great, especially from the account manager. We planned this engagement as a temporary setup, but the experience has been so good that we've extended our partnership. I'd be happy to seek further help from Interexy in the future.
How did Interexy perform from a project management standpoint?
The account manager's support is excellent; she's always finding ways to improve and consistently identifies any issues. She's also very open to feedback, making problem-solving easy for me. The developer works with our Scrum team and joins daily meetings. We use Azure DevOps with the team, which is our project management tool.
For official requests, we use email. Once Interexy teammates are integrated with the internal team, most communication happens through Slack or Zoom meetings. Additionally, I have regular sync meetings with the account manager via Zoom to exchange feedback about the resources and solve any issues. Through these calls, Interexy proposed the UI/UX designer.
What did you find most impressive about them?
I'm impressed with Interexy's communication skills, the quality of their resources, and their cost-effectiveness. When we needed a UI/UX designer, I looked at other options and found much higher rates than the ones Interexy has provided. They give us excellent service at a very competitive price.
Are there any areas they could improve?
Their level of English communication could be better. However, this has never been a significant issue.
Do you have any advice for potential customers?
Hurry up and go for Interexy — it's a no-brainer!

Interexy designed the product’s UI and developed a mobile application and an admin panel for a mental health platform. The app was an onboarding system for patients that used bank IDs to log in.
In less than three months, Interexy successfully delivered a stable application. External stakeholders gave overall positive feedback, and the client was impressed with the team’s project management. They communicated effectively through Slack, video meetings, Confluence, and Jira.
A Clutch analyst personally interviewed this
client over the phone. Below is an edited
transcript.
BACKGROUND
Introduce your business and what you do there.
I’m the CEO of Anatomia. We’re a mobile application for patients suffering from mild to moderate depression. We treat them with physical activity, lessons, and follow-up calls. Overall, we measure their well-being and physical capacity.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Interexy?
We needed help with mobile application development and UX/UI design services.
SOLUTION
What was the scope of their involvement?
Interexy developed our mobile application, its UI, and its admin panel. We started with the preparation stage, which included several hours to set up our goals and the product development program. They had many questions during this stage; we drew our thoughts in Miro and showed them the boards. Then, we moved on to sprints; there were four sprints in total.
The app was an onboarding system for patients. Users could onboard the program by logging in with their Swedish bank IDs to verify the patient. Then, users answered questions, including age, name, and gender. Additionally, there was a health questionnaire with nine questions that ranged from sleep and physical activity to concentration ability and lust for life.
Patients would be assigned to a physiotherapist, who would guide them through the program. They’d start with a physical training program, but the physiotherapist would also follow up daily through messages and follow-up calls on the first, sixth, and tenth weeks.
What is the team composition?
We worked with seven people, including front- and backend developers, QA people, business analysts, and project managers.
How did you come to work with Interexy?
Someone from our team recommended Interexy. They knew them from another company.
How much have you invested with them?
We spent about $75,000.
What is the status of this engagement?
We worked on the project from September–November 2022.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
Interexy has fixed some significant bugs and made the app stable. The application is out in the App Store and Google Play Store. We’ve tested with real patients and gotten a lot of feedback about the onboarding process and changes we could make, but the feedback has been good overall.
How did Interexy perform from a project management standpoint?
Communication was clear. The project manager kept us updated with the budget and development. We faced some obstacles on the way, especially with the bank integration, which increased the cost and delayed the product a bit. However, it was a smooth process and a good collaboration overall.
We mainly communicated through Slack and video meetings, but we also used Confluence and Jira for project management.
What did you find most impressive about them?
They stood out for their communication and project management skills. They kept deadlines and stayed within the budget.
Are there any areas they could improve?
The bank ID integration was challenging. We’d never done it, but it was especially well-suited for healthcare providers like us.
Do you have any advice for potential customers?
I’d definitely recommend them. However, if you integrate the bank ID, maybe consider using an external expert.
