What I'm looking for

I’m looking for a team where I can build language frontends and static-analysis pipelines end-to-end—partnering with security and ML—while shipping reliable production systems with strong CI, testing discipline, and developer-focused documentation.

I’m a Senior Full Stack Engineer with 10+ years building scalable web platforms, developer tooling, and AI-enabled analytics systems. My recent work focuses on language frontend development and program-analysis pipelines for automated vulnerability detection, with a strong emphasis on compiler and parser integration.

In my latest role, I led the design and implementation of 5 language frontends and parser integrations, improving analysis coverage by 48%. I translated compiler semantic models and Roslyn syntax trees into Joern Code Property Graphs (CPG), boosting CPG fidelity for method and type information by 92%, and delivered a framework processing 1M+ source files while reducing translation latency by 33%. I also maintained 200+ integration tests and CI pipelines, decreasing regressions by 60%, and containerized parser services to handle 5x peak analysis load. I collaborate closely with distributed teams and open source contributors, triaging parser issues, submitting 30+ PRs, and coordinating releases with thorough documentation and release notes.
