As a freelance Full-Stack Software Engineer, I engineered a custom search query parser that turns complex syntax into structured filters, and modernized a legacy Nest.js architecture with PostgreSQL, TypeORM, and multi-tenant role-based access control.

I also reduced PDF generation latency by 70% with a pre-warmed headless Chromium pool and developed multilingual Next.js platforms using PayloadCMS. My projects include a C compiler with an LLVM backend, a Rust Wayland desktop shell, and a Go CardDAV server.
