Hi — I build reliable, high-performance systems

I design and implement production-grade, multi-threaded systems and libraries in C++. I’m passionate about debugging low-level concurrency and performance issues, and about building scalable tools for both developers and customers.

🧭

Systems & Performance

Writing performant C++ (C++17) with focus on multithreading, memory safety, and low-latency critical paths.

🛠️

Developer Tools & Automation

Building and improving CI/CD, developer tooling, and workflows — including AI-assisted developer instructions and automation to boost traceability.

🤝

Collaboration & Mentorship

Mentoring engineers and coordinating cross-site teams to deliver robust APIs and libraries with clear usage and diagnostics.
