Everything has been really smooth, and they’re flexible and accommodating. Communication is great in general. We have weekly meetings, and they always respond within minutes or less than an hour. If they’re not going to meet a deadline, they communicate it, and it’s often because we asked for more work. Additionally, they are responsive when we find bugs. What did you find most impressive about them? We spoke to many developers, but what initially struck us about LambdaWorks was the people. They ask great questions, challenge things, and let us know when we ask to do something unfeasible or out of our budget. Do you have any advice for potential customers?

Novak Djokovic Foundation focuses on improving the settings and conditions of early childhood education and development for preschool aged children from socially disadvantaged municipalities throughout the Republic of Serbia. **OPPORTUNITY / CHALLENGE** For what projects/services did your company hire LambdaWorks? We had a lot of issues and challenges in gathering and obtaining the statistical data showcasing all of the primary indicators for the current state of children's well-being in different regions of our country. In order to pinpoint locations where the needs of children have reached an alarming level, we needed to gain access to different data sources, and organize them in one place. What were your goals for this project? Our main goal was to cross-reference all of the data sources within our country (and the differing results they were showing), so that we could calculate and measure exact indicators, and create an overview of the state of well-being of children on a national and regional level. **SOLUTION** How did you select this vendor? LambdaWorks were first consulted on a recommendation from one of our closest associates, as they had great experience in working with them. We were considering a couple of other companies, which we had the experience of working before, but felt that the team at LambdaWorks understood best what our need was, and how to create a product which would suit us. Describe the project and the services they provided in detail. Our team provided them with some of the data sources we were using up to now, and directed them towards additional sources which could be useful. Afterwards, their team created the platform based on our input on what we required both from the data side and the functionality of the future product. What was the team composition? Their team consisted of three people: one member who was negotiating and communicating with us, and two other members who did the technical part of the job. **RESULTS & FEEDBACK** Can you share any information that demonstrates the impact that this project has had on your business?

We've been using it for strategic planning of project locations for 2020, and the research we do before establishing projects within various municipalities. How was project management arranged and how effective was it? The project management side was very precise in communicating how they envisioned what the product could look like based on our input, which steps and deadlines they are setting, and which information they initially require in order to start their work. They were very respectful of all of the agreements we had, and successfully delivered the product on time. What did you find most impressive about this company? They were dedicated to making this product work, and they were very open to listening to our initial input, as well as the feedback we provided on each step. They catered to our specific needs, which is what we required from the start. Are there any areas for improvement? We wouldn't be able to focus specifically on what they could improve, as this wasn't as complicated a project, and was pretty straightforward in terms of the goals set and work required. --- #### Platform Development for B2B Data Company **The Project** - Services: Custom Software Development - Project size: $50,000 to $199,999 - Project length: Nov. 2018 - Ongoing **Project Summary**: LambdaWorks functions as the main product team for a B2B data company. They’ve built out a dynamic enterprise-level SaaS platform that features an AWS-heavy backend. **Review Rating**: 5.0 - Quality: 5.0 - Schedule: 5.0 - Cost: 5.0 - Willing to Refer: 5.0 **The Reviewer** CEO, Bizzit - Industry: Other industries - Client size: 1-10 Employees - Review Type: Phone Interview - Verified **The Review** — Feb 12, 2020 **Feedback Summary**: Besides their speed, LambdaWorks impresses with their talented pool of senior-tier engineers. The team is nimble, assigning resources based on the task at hand, which allows for a cost-effective price structure. Their ability to scale early-stage products also makes them particularly invaluable. ""I’ve worked with numerous levels of engineering, and their resources of some of the best I’ve ever seen." " **BACKGROUND** Introduce your business and what you do there. I’m the founder and CEO of a B2B SaaS startup. **OPPORTUNITY / CHALLENGE** What challenge were you trying to address with LambdaWorks? At a startup, there are various stages of developing a product. We were looking for good senior-level engineers to build out those stages based on our business goals. **SOLUTION** What was the scope of their involvement?  LambdaWorks serves as our product team. They’ve built and are continuing to work on our evolving SaaS platform. It’s an enterprise-grade data solution that relies on AWS as a database as well as having messaging systems.  What is the team composition?  The team changes based on the task at hand. I have two main points of contact: Bojan (CTO, LambdaWorks) and Filip (Product & Business Development, LambdaWorks). When we’re building the product, we usually bring on two other resources. This model allows us to pay for what we need and still get high-quality work without wasting resources. For example, we could switch in a Salesforce AppExchange developer only when working on our Salesforce app. How did you come to work with LambdaWorks? They were on our radar. I’d worked with product engineers in the area before, so I knew the landscape pretty well. After talking with Bojan, they were the clear choice. He was able to clearly lay out a lot of our requirements — not to mention, they’d already scaled another product in the US. How much have you invested with them? We’ve spent $60,000 to date, and it’s about to be another $40,000. They’re one of the best deals for the level of engineering that they provide. What is the status of this engagement? We started in November 2018, and the engagement is ongoing. **RESULTS & FEEDBACK** What evidence can you share that demonstrates the impact of the engagement? The quality of work is so good because they’re brilliant engineers. I used to ask some of my high-level product connections to oversee LambdaWorks’ output, but I don’t need to anymore. Their team doesn’t take any shortcuts either, which has helped us avoid creating technical debt.  How did LambdaWorks perform from a project management standpoint? When we’re in our routine, they set the schedule and provide weekly updates in a concise way, which is nice. The team communicates over video conference meetings, and we’re all in the same Slack channel. I’m now able to trust a lot of decisions that they make because I realized that I was inevitably saying yes to most things. That has allowed us to define levels of importance for certain requirements because they know what we’re doing and can bring their own level of creativity. What did you find most impressive about them? At the end of the day, it’s their quality that sticks out. They could charge a lot more if they were based in the US because their skills are that good, and they produce work relatively fast. I’ve worked with numerous levels of engineering, and their resources of some of the best I’ve ever seen. Are there any areas they could improve? Outside of the time difference, I don’t really have anything to add. Do you have any advice for potential customers? LambdaWorks specializes in scaling quality early-stage products. That means that it’s important to really give them detailed requirements — not just on short-term goals, but also looking at where you see the product five years from now. Keeping that in mind will help them build in the right flexibility into your product, which saves time and costs. --- #### Software Development, Mobile & Web Redesign for SuperPhone **The Project** - Services: Custom Software Development, UX/UI Design, Web Design - Project size: $1,000,000 to $9,999,999 - Project length: Mar. 2017 - Ongoing **Project Summary**: LambdaWorks develops and designs software for a phone number service company.
