About
Production engineering for AI-integrated products — the kind founders actually ship.
I build AI-integrated web applications for founders and product teams — multi-tenant SaaS, RAG pipelines, document automation, and the unglamorous glue around them. Python and FastAPI on the backend, React and TypeScript on the front, Supabase and n8n where they earn their keep.
Delivery is scoped, tracked, and tested. Jira board from kickoff, Claude Code in the loop, Playwright covering the critical paths. Fixed price, fixed scope, demo every Friday — you know what you are getting before you sign.
On the side I run a YouTube channel teaching the same stack — n8n workflows, AI agents, Telegram bots, automation patterns I keep re-using on client gigs. I am equally comfortable shipping the production code and explaining it on camera.
Bilingual: English and Ukrainian. If you have a build that needs to ship, the social cards below are the fastest way to reach me.

Pavlo did an excellent job building our CoinTapGo MVP. He was professional, responsive, and clear throughout the entire project. Communication was smooth, the work was completed properly, and he helped with setup, deployment, testing, and final delivery. I'm very satisfied with the result and appreciate his attention to detail, fast execution, and technical skills. I would be happy to work with Pavlo again on future improvements and the next stages of the project.

Teammate · May 2026
I had the pleasure to work with Pavlo on one of the projects. He demonstrated exceptional technical skills, consistently delivering new features quickly while maintaining a high level of quality and attention to detail. Pavlo always took ownership of the areas he was involved in and was willing to share his knowledge with the team, offering support whenever needed and proposing new ideas to improve both the product and development processes. He is very friendly, easy to communicate with, and a great collaborator when brainstorming solutions to complex problems. I would highly recommend Pavlo as a skilled and reliable engineer to any team.
Resource Manager · April 2026
I had the pleasure of working with Pavlo at EPAM Systems, where I was his Resource Manager. Pavlo proved himself to be a reliable and highly capable software engineer with strong expertise in full-stack development. He consistently demonstrated solid technical skills, ownership of tasks, and a responsible attitude toward delivery. Pavlo was able to work effectively both independently and as part of a team, quickly adapt to project needs, and maintain a high standard of quality in his work. What I especially appreciate is his proactive mindset, willingness to solve complex problems, and professional communication style. He is the kind of engineer who can be trusted with important responsibilities and who always strives for strong results. I can confidently recommend Pavlo as a skilled and dependable software engineer.
Direct report · April 2026
I had the pleasure of working under Pavlo's leadership, and I can confidently say he is one of the most skilled Node.js experts I've met. As a Team Lead, he doesn't just manage tasks; he ensures the entire team follows best practices and writes clean, scalable code. His deep understanding of backend architecture and performance optimization was instrumental to our project's success. Any team would be lucky to have him at the helm.
Team Lead · April 2026
I had the pleasure of working closely with Pavlo as his Team Lead, and he consistently stood out as a highly versatile Fullstack Developer. Pavlo possesses a vast technical toolkit, but what truly impresses me is his ability to bridge the gap between frontend and backend seamlessly. Whether he was crafting interfaces in React or building scalable logic with Node.js, his output was always high-quality and reliable. One of Pavlo's greatest strengths is his speed of learning. He can investigate and master unknown technologies in record time — for instance, he quickly became a go-to person for our integration with Microsoft Entra. His performance is consistently strong, and he has a natural knack for solving complex architectural challenges independently. I would highly recommend Pavlo to any engineering team.

Pavlo is not only a skilled professional but also a team player who enhances the work environment.

He has successfully completed the tasks of gathering and managing the process and regulatory requirements of the business team, ensuring that requirements are met within the final technical solution, while still understanding some of the pragmatic decisions needed to achieve the balance between cost / time and perfect design. The requirements also demonstrated his experience with translating business need into technical design. Pavlo has shown exceptional discipline in achieving professional and personal goals, strong inter-personal skills, and that he is a team member that makes work-life enjoyable.
