Peiko

I am CEO of Quan2um OU crypto service company.

We wanted to develop a mobile wallet app to store and transfer our clients' cryptoassets

Found them on a freelance website. There were a lot of companies/freelancers but we loved Peiko's approach, communication style and recent projects that they made

The quys from Peiko planned well our future project, the architecture,described all the technical documentation,developed the design, the mobile application and the server part

The team included 6 people. Designers team. Mobile app - developer -1 Backend - 2 QA engineer -1 PM + Business analytic (Dmitry, Bohdan) is our main contact

The project is being prepared for release, now passing the last security checks of the project.

The Peiko team knows their job well. As far as I know, they devided all works into 2 weeks sprints. For us it was good as we were sure that we will receive every part of work separately. They helped us work out the whole concept of the project in detail and then took care of all the project development. Also we started with a technical specification, which helped us divide a definition of done. It was really helpful at the end of the project. Our manager was Bohdan. He regularly gave us feedback on the work done and kept us informed about what the team was working on. We are greately satisfied withe the management of the project

Peiko's team is well versed in the direction of blockchain project development. They are ready to undertake all the complicated work on the architecture of the project and provide a finished product in the end.

The team is doing a very good job, We wish they could scale up and be able to work on more projects.

The team developed a scalable multi-tenant backend platform with RAG pipelines for document processing and contract intelligence, event-driven communication using Node.js, NestJS, and Kafka, optimized databases, AWS cloud setup, and technical documentation.

The deployment was successful, improving data analysis speed and reducing manual operational effort across global business units. The event-driven architecture ensured stable data synchronization between regions, while database optimization improved query execution times and server response speed.

The project was managed professionally and delivered through structured sprints. The team met agreed deadlines, provided valuable architectural input, and responded efficiently to evolving project requirements.

The vendor demonstrated strong engineering maturity and the ability to design resilient, scalable system architectures. Their expertise in Kafka-based data flows and enterprise-grade RAG pipelines helped create a solution that could support multiple international business structures and complex operational requirements.

We have no complaints or suggestions for changes. While the initial technical audit and architectural planning required a deep, data-heavy alignment, this meticulous preparation was exactly what enabled a flawless, bug-free launch of a highly complex system.

The vendor took full charge of the development lifecycle, starting with a deeply detailed discovery phase to map out our complex cryptographic and infrastructure constraints. They engineered a powerful backend architecture, implemented military-grade encryption modules, and designed intuitive asset management flows. Key deliverables included a fully audited and operational custody core, highly resilient REST/Webhook APIs, robust multi-sig verification protocols, a prioritized product backlog, and extensive technical documentation.

The final architecture demonstrated absolute stability and structural precision during our rigid technical validation and external security audits. Beyond the code execution itself, they handed over a completely market-ready, high-fidelity platform. The custodial core is fully operational and safely manages significant digital assets, giving us the exact operational predictability needed for our institutional rollout.

The engineering process was highly organized, transparent, and structured into predictable development milestones. All key deliverables were met strictly on schedule. Rather than acting as a passive vendor, their team was highly proactive; they actively audited our feature ideas and helped us prioritize the scope based on our long-term business goals. They adapted to our feedback instantly, adjusting complex details without compromising the core technical requirements.

What sets them apart is their rare ability to bridge the gap between highly complex cryptographic research and practical, scalable business logic. Their team took absolute ownership of the product's foundation right from day one. Their systematic, disciplined approach to documentation and feature filtering prevented any technical bloat, which saved us massive resources and provided an exceptional level of technical predictability in a high-security space.

The entire deployment was handled with full professional discipline from start to finish. The initial architectural planning and discovery stage required a heavy, data-intensive alignment, but this deep preparation was exactly what enabled a flawless, bug-free launch. We would not change anything about their process.

The team managed the full product lifecycle from day one. We started with a highly intensive Discovery Phase focused on mapping out complex blockchain data processing. From there, they architected and engineered the entire backend system using Node.js and Next.js, developed scalable microservices, and deployed robust REST/Webhook APIs to handle heavy data flows. They delivered a fully functional RegTech platform complete with professional-grade documentation, an intuitive user interface for complex reporting, and a well-structured product backlog. The system is now fully operational and completely aligns with international compliance standards.

The defining metric for us was the absolute precision of the final architecture, which demonstrated flawless consistency during technical validation and external audit. Instead of delivering a basic MVP, they handed over a high-fidelity, market-ready asset. The engine runs smoothly under high concurrent loads, giving us a highly predictable, confident path toward institutional adoption and global expansion.

Their project management was structured, highly organized, and fully transparent throughout the development cycle. They followed a clear workflow from the initial Discovery Phase to final deployment, keeping every milestone strictly on track. The team was incredibly proactive; rather than waiting for a checklist of tasks, they actively collaborated with us to prioritize features based on our long-term business goals. They responded to our feedback instantly, adapting quickly without ever losing sight of our core technical requirements.

What stood out most was their ability to bridge the gap between complex financial research and practical business logic. Many engineering teams can write functional code, but this vendor took genuine ownership of the product's foundation right from the Discovery Phase. Their systematic approach to documentation and feature prioritization ensured we didn't waste valuable resources on unnecessary complexity, providing a level of technical predictability that is exceptionally rare in the FinTech and compliance space.

The partnership was handled with total professionalism from start to finish. While the initial planning and architecture phase was highly intensive, it was entirely necessary to guarantee a smooth, flawless launch. We would not change anything about their execution or process.

The vendor took full charge of the engineering process, starting with an extensive discovery phase where we mapped out our on-chain logic. They built out a robust backend infrastructure using Node.js and Next.js, developed and integrated secure Solidity smart contracts for reward distribution, and created an intuitive portal interface. They also implemented independent voting modules to handle decentralized governance. Key deliverables included a fully audited Web3 platform, functional REST and Webhook APIs, a highly prioritized product backlog, and clean technical documentation for our internal maintainers.

The architecture they delivered proved to be exceptionally solid during our technical validation phases. Instead of handing over a fragile prototype, they supplied a secure, live ecosystem that integrates cleanly with our core network. The platform handles high transaction loads without state errors or unexpected downtime, giving us the exact operational confidence we needed to begin our global expansion phase.

The engineering cycle was driven by practical, structured sprints. Every key deployment was delivered exactly within the agreed timeframe. Rather than just taking orders, their engineers acted as active tech consultants, analyzing our project scope to eliminate unnecessary technical debt early on. They caught edge cases in our governance logic before they could become problems and integrated updates seamlessly.

What sets them apart is their strong grip on Web3 business realities. They don't over-complicate systems or write code for the sake of coding. By forcing structured documentation and prioritizing the absolute security of the staking smart contracts, they provided a level of engineering predictability that saved us a massive amount of development resources.

The deployment was handled flawlessly. The upfront architecture planning was rigorous and demanded intense alignment, but it was completely justified since it led to a stable, bug-free production launch. We have no complaints regarding their performance.
