At HestaBit Technologies, I engineered the planner, SQL-writer, and semantic-resolver agents, along with the orchestrator, for QBIT, a production LangGraph text-to-SQL platform spanning Snowflake and Databricks.
I added query guards and SQL validation to stop invalid requests and malformed queries before execution. I also designed Postgres caches to reduce repeat LLM calls and added controls for agent retries and partial-result recovery.
For BG Wheels, I built a Node.js pipeline that imported a supplier CSV into the client's live Shopify store, publishing 72 products and 853 variants with zero failed imports. I also fixed a concurrency race and patched theme templates so imported products were enquiry-only.
In a project internship at IBM, I led a six-member team building news topic-modelling pipelines and a Streamlit dashboard. My projects include a credential-isolated AI task agent and a satellite dam-monitoring pipeline using geospatial imagery.
