Location: San Francisco, CA and Los Angeles, CA
Remote: Yes, hybrid considered for the right money.
Willing to relocate: Not at this time
Current Level: Senior Staff / Principle / Lead
I'm a seasoned generalist with deep focus in certain areas such as game development, performance engineering, systems engineering, low-level engineering and embedded software.
What I shipped this year for money: Performance improvements to HFT code (Rust & C++) for financial trading. Firmware for the hardware of an ereader (Rust+ARM).
What I shipped last year for money: High performance (C++) server backend for a video game.
Current side-project: Deep internals work on VS Code Web: using quilt to maintain patches against upstream, extending it with inline agent panels and custom completion providers, backed by a bespoke C# server replacing the Node.js REH with my own dedicated server - similar in spirit to Coder's Code Server or OpenVSCode-Server.
Technologies: kernel drivers, systems engineering, video games, AI, LLMs, caching, graphics, rendering, assembly languages, generative AI, heavy focus on back-end systems, and to a lesser degreee, full-stack.
- Languages: C++, C, C#, Go, Rust, TypeScript, JavaScript, Python, Ruby, Lua, + more.
- Backend: node, FastAPI, Django, PostgreSQL, mySQL, RocksDB, GraphQL, SQLite.
- Engines: DumpsterFire, UnrealEngine, Unity3D.
- Platforms: Windows, macOS, iOS, Android, Linux, SONY PS2/3/4, XBOX360/One, Switch, embedded, web
- Frontend: Next, React, Vue, Pixi
- DevOps/Cloud: AWS, Docker, Kubernetes, VMs, Vagrant, VMWare, TeamCity, Jenkins, CI/CD
- AI/ML: Model training/tuning, LoRa, RAGs, PyTorch, TensorFlow, SciKit, OpenCV, etc, etc, generative AI and computer vision.
- LLM Integrations: OpenAI, Gemini, Claude plus many others, local and cloud.

MSc in CompSci and MSc in AI/Robotics
20+ years of experience in performance critical systems engineering, video game development, embedded (C/C++/Rust/Asm), low-level engineering & AI, full stack and high performance backends.
Open to full time or contract. Looking for something low-stress and interesting, so open to unconventional setups, but base comp still needs to be grounded in reality.
