      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.

      Blockchain Review from Valeriia Subota

      Peiko developed a complex stablecoin management platform for us from the ground up. They successfully took over the entire lifecycle, delivering critical technical documentation and UI/UX design where previous teams had struggled.The expertise of their Business Analysis team was exceptionalthey translated our vision into a robust technical architecture with precision. 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. A highly reliable choice for any high-stakes blockchain or fintech venture.

      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.

      Working with A1QA has been exceptional since the very beginning. Their professionalism, efficiency, and quality of work often exceed what we’ve seen from much larger providers. From the early planning stages through test execution and continuous improvements, the team has shown strong expertise and maintained clear, reliable communication. Their dedicated focus on QA has given us an experienced group that manages the entire process with little need for oversight on our side. They are true experts in their field.

      Software Development Review from Claus-Peter Mueller

      We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.

      We decided to create an Online shop for selling medicines. So we started with negotiations of the concept and the collection of the requirements. Then team provided us with the technical description of the store and a few mockups of it. After approving everything they start creating a solution.I think that we're about 10-12 people in the team who worked with us. We launched shop and receiving profit from it, I think that's the best outcome.
