Blockchain Review from Sergei Bliznyuk

We've been working with Peiko on a complex blockchain infrastructure project, focused on building a custom Layer-2 scaling solution for our ecosystem. The goal was to reduce network congestion and lower gas fees, and their team has been involved from the initial discovery phase through ongoing development.What stands out most is their ability to turn complex blockchain concepts into practical solutions that align with real business needs. They don't just execute tasks, they actively contribute to shaping the product, helping prioritize features based on long-term goals. Their technical expertise is strong, and theyve delivered solid documentation, a clear backlog, and well-optimized smart contracts.Communication has been smooth overall. At one point, we adjusted the format of updates to get more visibility into the process, and they were quick to adapt and provide more detailed insights without any friction.The project is still ongoing, but the solution is already partially implemented and integrated into our ecosystem. So far, the collaboration has been professional, flexible, and well-managed.

The high-quality MVP they delivered was instrumental in helping us secure VC funding. Throughout the process, the team maintained seamless communication and provided direct access to the developers, ensuring the project was completed exactly on schedule.

Blockchain Review from Catherine Ilashchuk

If you're building something technical, you know how easy it is for things to go off the rails. Peiko is the first team Ive worked with that actually got ahead of those issues before they started.Instead of just taking our money and starting to code, they forced us to slow down and nail the architecture and logic first. At the time, I just wanted to move fast, but that planning phase is the only reason we haven't had to rebuild half the platform mid-way through. They caught logic gaps we hadn't even considered.The communication is solid, no fluff, just direct updates on where we stand. They also didn't just build whatever I asked for; they pushed back when they thought a feature would bloat the MVP or mess with our timeline. Having a team that actually thinks about your budget and your launch goals like a partner, rather than just a vendor, makes a massive difference. Were heading into our next round of funding with a product that actually works and documentation that proves it.

Web Development Review from Anita Krol

We entrusted DevsData with developing a new website for our company. I was impressed by how quickly their team completed the project. They gave the site a new, modern style with appealing layouts and they connected marketing tools for measuring user behavior, which led to a noticeable boost in our company's revenue. What I'm most delighted with is that we received regular updates on every stage of the process. DevsData did a marvelous job and helped us get our business off the ground quickly.

IT Staffing Review from Adam Zaczek

I contacted DevsData to recruit two Node developers for our startup (CodeAlly). We started from creating detailed job descriptions for the desired role, together with DevsData, and agreed on the compensation ranges. Then every week, we had an update call with a couple of new developers that were recommended our way. They did an outstanding job. I signed 2 developers. Everything went smoothly as I had hoped. I will definitely work with them again for my future tech recruiting needs.
