I work on databases, developer tools, and agent infrastructure, primarily in Go, Rust, Python, TypeScript, and Mojo.

`~/projects`

omendb — Relational database for single-node OLTP in Rust on SeerDB, with PostgreSQL compatibility at the wire boundary. Developer preview, not alpha-ready. (WIP)
omendb-vector — Embedded retrieval database in Rust for mutable application data: vector search, BM25 text search, metadata filtering, and hybrid ranking. Developer preview. (WIP)
seerdb — Transactional ordered byte-KV storage engine in Rust, developed in the OmenDB workspace as an independently versioned Apache-2.0 crate. WAL recovery, snapshots, and group commit. Developer preview. (WIP)
omengrep — Local code search CLI in Rust: Tree-sitter extraction, embeddings plus BM25, owned local storage. Under rewrite. (WIP)
mem — Local memory CLI for agents: durable facts and decisions, past-session history with source references, per-workspace resume state. SQLite with FTS5, no daemon. Pre-1.0, interfaces may change. (WIP)
hnsw-go — HNSW approximate nearest-neighbor search in pure Go, mmap-backed, with filtering and segment merging.
stt-bench — Speech-to-text benchmarking across 13 acoustic conditions and four models.

ion — Terminal coding agent in Rust: model-facing loop on a single-writer session runtime. Clean-sheet v0 rewrite. (WIP)
pi-search — Pi extension for web search, native provider search, page fetching, and local document extraction.
pi-fast-mode — Pi extension for OpenAI Codex fast mode.
pi-compactor — LLM-driven context compaction for coding agents.
pi-subagents — Agent delegation for pi with sequential chains and parallel execution.
pi-workflows — Durable, resumable workflow orchestration for pi.
pi-goal — Session-scoped autonomous goals for pi.
pi-usage — Pi extension that shows OpenAI Codex subscription quota in the footer.
pi-tps — Pi extension that shows per-request latency and throughput under each response, with session averages in the footer.

sy — File synchronization in Rust with rsync-like behavior: delta transfer, parallel I/O, SSH, and reflink support. v3 rewrite in progress. (WIP)
aku — Type-safe Go API framework built on net/http, with request extraction, validation, and OpenAPI generation.
jb — Background job manager for long-running CLI tasks.
tk — Task tracker for AI agents with Git-friendly storage and blocking dependencies.
brotli — Pure-Go Brotli encoder/decoder (RFC 7932; large-window and multi-stream decode per RFC 9841), drop-in for andybalholm/brotli.
brutli — Rust Brotli implementation from the spec. Decoder works and the one-shot encoder emits compressed and stored streams; still in compatibility, corpus, and performance validation, not production-ready. (WIP)

archon (private, WIP) — Distributed resource manager in Rust: discovery, scheduling, enforceable leases, process and container execution, health and recovery. Lab-proven, not production-scale.
engine (private, WIP) — Model inference runtime in Rust: loading and execution, quantized and server inference, batching and scheduling, cache management, hardware backends. Early development; first target is single-GPU NVIDIA.

go-clob-client — Go SDK for the Polymarket CLOB with trading, authentication, and order signing. Unofficial, not production-tested.
pacabot (private) — Prediction-market research system using LLMs to analyze market data, news, SEC filings, and congressional trades.
