Custom Software Development for Investment Company
Overview
MXNEY is an easy-to-use eCommerce funding platform that allows users to get financing in a few clicks. All the entrepreneurs have to do is connect their store with the platform to select funding offers. With an advanced repayment calculator, business owners see their sales plan and, based on it, compensate a small percentage to the platform.
Automated processes
Finally, it was time to make this SaaS platform more convenient by automating some processes that have been done manually before. Primarily, this involves reviewing client onboarding.
So we:
- Introduced an automatic lead database with a dynamic rules system
- Implemented the KYC (Know Your Customer) identity verification system
- Set up open banking for speeding up the due diligence process
- Created a single gateway for integrating online shopping platforms such as Shopify, Magento, and WooCommerce
- Reduced the number of the compulsory registration steps by fetching some of the required documents and data automatically
As a result, Perfsol added much-needed automation and standardization to the MXNEY user journey.
“They've been good at getting their heads into our business, so they understand what we're trying to do. In the beginning, we had long meetings about what we are trying to achieve; our goals and visions, what our product is, and how we can make money. I have worked with other agencies that didn’t put themselves into the project and didn’t understand it.”

Taxi app development
The platform sets itself apart as the first rideshare mobile solution that allows riders to choose vehicles based on their carbon footprint. Besides, it calculates the amount of carbon emitted during the trip and donates the offset to tree-planting initiatives.
Challenge
The idea to build the first sustainable ride-sharing was (and remains) unique. Yet, in our mobile-first age, even the most brilliant idea won’t succeed without an intuitive yet robust mobile app
Solution
At Perfsol, we were inspired by our partner’s vision to turn something as simple as hailing a ride into a collective attempt for a change. That’s why we wanted to ensure the solution would reach its customers while catering to their needs. Here’s how the Android app for the rideshare solution was born.
Based on Kotlin and Android SDK, the app is on par with other Uber-like solutions. Thanks to the user-friendly GEO location search function, it allows passengers to find the nearest drivers, choose the most environmentally friendly vehicle, and select the most convenient route. In addition to that, users can review the fare beforehand and pay by Visa or MasterCard.

Custom Software Development for Investment Company
"I don't think there's anything they can improve on — I think they are great, and we're happy with them."
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I'm the CTO at MXNEY, an investment company.
What challenge were you trying to address with Perfsol?
We were building a huge platform, but we lacked developers.
What was the scope of their involvement?
Perfsol has been mainly assisting us with project management, the whole platform scope, and the actual development of the platform.
They also have been helping us with both our backend and frontend; for the frontend, we have mainly been using React, JavaScript, HTML, and CSS, and on the backend, it was primarily a PHP framework called Laravel.
Additionally, they work closely with me in managing and getting developers in Ukraine while looking at the structure of the team and project, such as the features we're building and in which order, and how we can organize the architecture to be sufficient. They've great experience in AWS and bear with me on different questions I have.
What is the team composition?
I've been working with the CTO. In the beginning, he was working on development as well, and since then, he has been in more of a managing project leader role. I have also been working with two frontend developers and two backend developers. In total, there are five people involved in my project.
How did you come to work with Perfsol?
I found them on Upwork; I saw their profile and invited them to the job because I saw that they had a great experience in the areas we were looking for.
How much have you invested in them?
We've spent around $25,000 with them so far.
What is the status of this engagement?
We began working with them in May 2021, and the work is ongoing. We have an excellent partnership with them right now, and I expect to use them for the longer term.
What evidence can you share that demonstrates the impact of the engagement?
Before working with them, we had three developers in-house, and from January to May, we released around four different features in one project. With Perfsol, from May to the beginning of August, we have released nine different features in two different projects — our development speed has increased a lot.
Also, the scalability we have has been perfect for us. We can hire a new developer within one month, whereas we would have a three-month recruiting period in Denmark.
How did Perfsol perform from a project management standpoint?
We almost always hit the target when it comes to our estimates for different tasks. Of course, there are some alternatives, and also, as we are a startup, we change things and change focus sometimes, so they have done things perfectly.
In terms of communication, we have a Slack channel where we communicate all day long. They are responsive — I feel like I can get in touch at any time of the day and get a quick answer. We also have a daily meeting for about 20 minutes to catch up on all of our features or tasks — it's like they are in-house because they're reachable, and I can even text them all day long. We had one weekend where one of our systems was down, and I immediately messaged them in our Slack group; two of the guys were on the case even on the weekend, so it was perfect. We have also been using Trello and Jira for project management.
We technically have a B2B relationship, but I see it as a close collaboration where they are working for us in a different country — they are dedicated to our company, which is fantastic.
What did you find most impressive about them?
They've been good at getting their heads into our business, so they understand what we're trying to do. In the beginning, we had long meetings about what we are trying to achieve; our goals and visions, what our product is, and how we can make money. I have worked with other agencies that didn’t put themselves into the project and didn’t understand it.
Are there any areas they could improve?
I don't think there's anything they can improve on — I think they are great, and we're happy with them.
Do you have any advice for potential customers?
I recommend that you use some hours to let Perfsol understand your business and the scope. They're good at that, and I think it allows for the best collaboration. Also, engage with them personally as well — they're located only three hours from us, and I'm flying down there in a couple of weeks to meet them in person, and I think it is essential too. It goes beyond a supplier and customer relationship.

“They’re proactive in asking us how they can improve their performance and extending their support.”
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I’m the technical product manager at serVme, a reservation management system. I’m responsible for building the technical department as well as the processes between departments.
What challenge were you trying to address with PerfSol?
We were looking to recruit some developers to develop our platform. I proposed that in order to do a good job, we needed to hire third-party services while looking for in-house developers.
What was the scope of their involvement?
We provided their team with the tech requirements, and they proceeded to develop our SaaS platform. They implemented both the front- and backend. A significant portion of the work was for the backend, implementing optimal APIs for communication between the frontends of our Android application, iOS application, and the website.
They also delivered performance enhancements, which we asked them to outline in the form of technical documentation. They’ve proven to be very reliable as we’ve consulted with them on specific scenarios and best practices. We’re still needing support, so we plan on working with them for a while.
What is the team composition?
I worked and managed their developers.
How did you come to work with PerfSol?
I knew Mykola (Co-founder & CTO, PerfSol) from earlier projects. As a freelancer, he worked on some of my past projects. I suggested that we hire his team at PerfSol because those previous projects were successful, and he had been a pleasure to work with.
How much have you invested with them?
While I can’t provide total amounts, we pay them $18-$20 per hour of work, per person.
What is the status of this engagement?
We started working together in October 2018 and the work is ongoing.
What evidence can you share that demonstrates the impact of the engagement?
PerfSol has become an integral part of our backend development team. They’ve added great value with their expertise, and have largely contributed to project progress.
How did PerfSol perform from a project management standpoint?
We communicate via phone and participate in daily meetings through Slack. In addition to that, we sometimes have Zoom meetings.
What did you find most impressive about them?
Whenever we had a complaint about an inaccurate estimation, they diligently reformed their approach and worked to enhance their services. They’re proactive in asking us how they can improve their performance and extending their support.
Are there any areas they could improve?
They couple improve their communication skills. The developers aren’t native English speakers, so while we haven’t had any major issues, we’ve experienced some difficulties in communicating business requirements.

Mainly their can -do attitude, proceeding at times without us having to give them detailed specifications, we both willing to proceed and agree not to sweat the small stuff, and cleaned that up when schedules allowed.
