I work on AI systems infrastructure: runtime systems, serving infrastructure, agent control planes, and memory-oriented systems for intelligent applications.
My interests sit where AI workloads meet systems engineering: making model-driven systems faster, more reliable, easier to coordinate, and easier to reason about under real implementation constraints.
- AI runtime and serving: CUDA, profiling, scheduling, memory management, vLLM, SGLang, Triton.
- Agent control planes: task scheduling, state consistency, recovery, auditability, runtime interfaces.
- Memory and graph intelligence: structured memory, temporal graphs, GraphRAG, provenance, relationship reasoning.
- World models and RL: environment modeling, long-horizon planning, policy learning, agentic behavior.
- Personal AI OS: knowledge-work systems for research, engineering practice, and local automation.
- coro: A C++20 coroutine runtime exploration for Linux async I/O, focused on coroutine primitives, scheduler design, and the practical engineering needed to make high-performance systems testable.
- raft: A strongly consistent control-plane project for agent runtimes and long-running task orchestration, exploring how leases, ownership, checkpoints, and idempotency can make distributed agent work safer.
- sptem-graph: A local-first memory control-plane project for AI agents, focused on auditable belief state, evidence trails, timeline branching, replay, and memory governance.
Some of these projects are still being shaped before public release, so I keep public descriptions high-level and use the work mainly to sharpen system design, implementation discipline, and research taste.
- I prefer small, verifiable changes over broad rewrites.
- I care about clear documentation, reproducible commands, and scoped commits.
- I like systems where the architecture can be explained from the code and tested locally.
- I try to separate product shape, architecture, and task tracking so projects stay understandable as they evolve.
- I use AI tools as engineering collaborators, but I still treat source code, tests, and docs as the final source of truth.
