Things I've built
Local personal AI agent with LangGraph orchestration (plan → tool calls → results), a FastAPI backend, a React cockpit, and SQLite + FTS5 RAG memory spanning semantic, episodic, and procedural recall with background consolidation. MCP gateway for Gmail, Calendar, and search, with human-in-the-loop approval on high-risk sends.
Plans property-carrying HGV trips and generates FMCSA driver daily logs under the 70hr/8-day HOS ruleset — routing, required fuel/pickup/drop-off stops, and one log sheet per calendar day in home-terminal time.
Redis-backed durable job queue with leased workers, exponential-backoff retries, a dead-letter queue, and idempotent enqueue for horizontally scaled consumers. Drained 2,000 jobs at ~5.4k jobs/s with 4 workers; recovered in-flight jobs after a crash; 200 concurrent idempotent requests collapsed to 1 job.
