ABOUT
I'm a Software Engineer with over 4 years of experience building web, mobile, and backend products with TypeScript, React, Next.js, React Native, NestJS, and PostgreSQL.
My work is centered around systems that need to behave correctly under real-world constraints: concurrency, failures, payments, integrations, unclear requirements, business pressure, and scale.
I care about pragmatic engineering decisions, reliable systems, clear architecture, and product impact over technical vanity.
Reliability over cleverness Clear systems over accidental complexity Product impact over technical vanity Simple interfaces for complex problems Pragmatic architecture for real constraints
