What I'm looking for

I’m looking to lead full-stack delivery on production SaaS—owning architecture, microservices, and UI—while partnering with stakeholders to ship fast. I value reliability, type-safe APIs, strong engineering standards, and environments where I can mentor.

I’m a full-stack software engineer with hands-on experience building and scaling production SaaS products and microservices for startups. I’ve led end-to-end delivery across backend architecture, microservices infrastructure, and frontend execution, with a strong focus on reliability and scalability.

As a Technical Lead at Tayst AI (New York, Remote), I owned the architecture and delivery of the company’s backend, frontend, and microservices stack. I defined engineering standards, reviewed PRs, mentored junior contributors, and drove type-safe API patterns that reduced runtime errors across the codebase.

Before that, I served as a Founding Engineer at Tayst AI (New York, Remote), where I built the scalable backend and microservices infrastructure from the ground up. I used Node.js, Nest.js, and PostgreSQL to establish database schema, authentication flows, and API contracts early, while also contributing to frontend delivery using Next.js and React.

I also bring broad product-minded execution from roles like Frontend Developer at Portals (London, Remote), where I built dynamic, responsive UI using Next.js, React, TypeScript, and Tailwind CSS. Beyond my work, I’m a proven open-source contributor with 550+ GitHub stars and many fullstack projects maintained in production contexts.
