TESTIMONIAL
Client words“He doesn't justwrite code. He buildsproducts.”
David ChamberlainCo-Founder at BetastateI've worked closely with Andrei while building multiple products and I can say without hesitation that he operates at a different level to most developers.
Andrei thinks like a founder. He understands why something is being built, challenges assumptions, and moves fast without sacrificing quality. He's able to take an idea from rough concept to working, production-ready implementation with very little hand-holding. That combination of speed, ownership, and product intuition is rare.
What stood out most to me was his ability to operate with urgency while still making thoughtful architectural decisions. He's comfortable navigating ambiguity, breaking complex problems down, and shipping meaningful progress quickly.
If you're looking for a developer who acts like a true product partner and not just someone completing tickets, Andrei is exceptional. I'd work with him again without hesitation.
