Hi 👋 I'm Andrei, an Engineer based in Timișoara, Romania. I view software engineering as a cohesive, end-to-end discipline. With over 14 years of development experience, my core focus is building full-stack applications where frontend rendering performance, deep interface accessibility, and strictly typed backend components operate in perfect synchronization. I also deeply value collaboration, and I genuinely enjoy working alongside others to build great things.

I lean toward clean code, strict type safety, and architectures built for the messy reality of production. Over the last decade, I've specialized in pulling heavy lifting off legacy backends—whether that means implementing SSE for live data streams or rebuilding enterprise ERP modules from scratch. When I step away from the keyboard, I'm usually trying to perfect the hydration metrics of a whole-wheat pizza dough. Currently, I am focused on my personal projects and open to new full-stack opportunities and technical collaborations.

Engineering Architecture

A deep look into my 14+ years of full-stack engineering history, showing the concrete architecture, tooling setups, and metrics backing my architectural choices.

  • Type Safety & Core Architecture

    Building modular, strictly typed TypeScript systems designed to minimize technical debt and keep production code maintainable.

  • Interface & Rendering Power

    Designing responsive UIs that efficiently handle heavy datasets, offloading heavy computations from legacy backends to protect UI responsiveness.

  • Automation & System Tuning

    Boosting development velocity by pairing sound automated testing with custom, local LLM integrations for intelligent engineering pipelines.
