Profile

A year ago, I shared my journey bootstrapping Audioscrape in Rust. Back then: 500 users, SQLite, 4k LoC in main.rs, running on a $7/month VM.Today: 25,000+ transcribed episodes, knowledge graph with AI-extracted entities, and still running lean.What changed:Tech evolution: SQLite → PostgreSQL (scale). Added OpenSearch for full-text + semantic search. Self-hosted WhisperX on 2 GPUs (~100 episodes/hour). OpenAI for entity extraction (people, companies, topics). Still Rust/Axum, now ~15k LoC.New features: Speaker diarization (who said what) using voice fingerprinting. Entity pages linking mentions across episodes. Timestamp-based sharing and deep linking. MCP server for AI agents to search podc
