I build tools for AI agents and contribute across open source, with 290+ changes merged into 140+ repositories in Python, Rust, Go, TypeScript, C/C++, and Java for organizations like Nous Research, NVIDIA, Sakana AI, Qwen, Tencent, Hugging Face, Apache, and Mozilla. Most of my focus is on agent memory, evaluation, and self-evolution, including ongoing work on Hermes Agent alongside Hermes Agent Self-Evolution, SkillEvaluator, Molt, ShinkaEvolve, autocontext, and headlong.

Among other projects, I created Compartment, an encrypted, offline memory server for AI agents that ships in the Hermes Agent plugin catalog and has one click setup with Anthropic's Claude Code and Claude Desktop, OpenAI Codex, Cursor, VS Code, OpenClaw, and other MCP clients. Rather than plain vector storage, it keeps single-claim memories with source provenance, links them in an entity graph, tracks opinion updates separately from facts, and recalls them in ~12 ms with hybrid vector and keyword search.

Challenges authored for Datacurve's ShipD platform, each accepted after automated checks, solver runs and human review; ten are included here as examples, with the hidden tests and reference solutions withheld to protect Datacurve's proprietary benchmark material:
