Back to original languageAbout Boris
Lead Fullstack Dev, Architect & PO — for startups that want to move fast, well, with a human in the loop.
15 years of technical experience, two projects I'm building in parallel (GTM, user discovery, hands-on PO), and a strong preference for small teams where every decision counts.
Full-stack (Java, Angular, React, NestJS, Python), scalable architecture, AI/ML — production RAGs, agents, harness engineering, and Claude Code to multiply velocity. I take on the PO role when needed to translate business needs into an actionable backlog.
What I bring:
✅ Rare versatility: back-end, front-end, DevOps, AI, architecture. One person, low coordination costs.
✅ Founder mentality: I build my own products, so I speak MVP, scope-cutting, and trade-offs. I understand founder constraints because I live them too.
✅ Pragmatic: simple, maintainable, scalable solutions. No over-engineering.
✅ People-focused: I believe we work better when we get along. I listen, I share, I train — several former juniors still reach out.
My current projects:
🌱 manyformany.org — a platform to help non-profits mobilize and engage their volunteers.
💬 Skoa — a tool to improve Quality of Work Life and employer-employee relations in SMEs without dedicated HR. Sensitive questions asked anonymously.
Recent missions:
• ESG reporting for a startup, in a 3-person squad — acquired 6 months later.
• Complex data configuration tool + in-house AI model for an early-stage fintech — acquired 2 years later.
• Scale-up legacy system overhaul: -50% bugs, significantly improved velocity.
• Design and production deployment of AI RAGs and agents, harness engineering with Claude Code to accelerate development.
• Mentoring junior developers.
My playgrounds: early-stage, fast decisions, small teams, impact-driven topics (forGood).
Off the keyboard: surfing, wingfoiling, woodworking, improv, music, basketball, family, doing my best.
