About

I am a systems engineer focusing on C++ for embedded and high-performance applications. This site collects practical notes, design patterns, and performance tips that I use when building reliable, maintainable software.

What I write about

• Modern C++ idioms and best practices
• Resource management and RAII
• Low-latency and deterministic programming
• Testing, tooling, and build systems

Experience

I have worked across firmware and application layers on commercially deployed products, focusing on predictable resource usage, safe concurrency primitives, and reproducible build systems.

• Senior Embedded Engineer — real-time communications stack, deterministic messaging (5 yrs)
• Systems Engineer — cross-platform toolchain and CI pipelines (3 yrs)
• Performance Engineer — microbenchmarking and cache-aware optimizations (2 yrs)

Skills

Primarily C++ and low-level systems, with a focus on predictable behavior and tooling:

• C++17/20, RAII patterns, ownership models
• Deterministic RTOS patterns, lock-free algorithms
• Build systems: CMake, reproducible cross-compilation
• Benchmarking, profiling, and performance analysis

Speaking & Workshops

I give short, focused workshops on reliable embedded development and tooling practices. If you'd like to arrange a talk or workshop, reach out via the contact page.
