What I'm looking for

I am seeking a collaborative, product‑focused engineering role where I can build scalable web/backend systems, mentor teammates, and deliver measurable business impact.

I am a full‑stack software engineer with hands‑on experience building payment, streaming, Web3 and healthcare platforms using TypeScript, Node/NestJS, Next.js, React, PostgreSQL and GraphQL. I have led UI and backend architecture efforts, developed reusable component libraries, and implemented performance‑focused database queries that supported significant revenue growth.

Throughout university and multiple startups I combined engineering rigor with product focus — shipping revenue‑impacting features, improving SEO and discoverability, and deploying robust backends for high‑value domains like payments, health and crypto. I enjoy collaborative teams, mentoring through community groups, and solving hard system and algorithmic problems.
