At 1AK-GROUP, I moved report data out of direct 1C queries and into a PostgreSQL copy, keeping it current with shadow updates. On uncached requests, the new dashboard was a median 11.7x faster across nine tested periods, and totals matched in every period tested.
At LWO (Light Well Organization), I made a multi-turn RAG assistant restart-safe with LangGraph and SQLite checkpoints, and added hybrid retrieval to find exact identifiers. I also built production integrations and voice-assistant workflows; in my personal project RAG-Studio, I'm building a local RAG platform with hybrid retrieval, reranking, and semantic caching.
