Full-stack Product Engineer building modern, production-ready apps for companies and myself.

Over the past decade, I’ve worked as a freelance full-stack developer mostly with startups and small businesses. In 2020 I decided to deepen my business and product knowledge, to build outstanding products.

As of now, I work at the overlap of product strategy and hands-on engineering. I can operate at the architecture and technical leadership layer, then drop into implementation when delivery needs direct execution. In fact, I love building things as much as I love planning them.

Most of my work is with founders and small teams that want senior decision-making without heavy process overhead. The goal is to ship useful things quickly while keeping the system understandable, maintainable, and low complexity. Keeping the AI tools in check and using them extensively but with the right oversight.
