At HestaBit Technologies, I engineered the planner, SQL-writer, and semantic-resolver agents, along with the orchestrator, for QBIT, an in-house LangGraph text-to-SQL platform. It brought datasets across Snowflake and Databricks into one catalog.
I built an intent guard that stops invalid or incomplete queries before they enter the pipeline, and a SQL validation gate that blocks malformed and non-SELECT queries. I also added caches and bounded agent budgets to reduce repeated LLM calls and prevent runaway loops.
For BG Wheels, I built a Node.js catalog pipeline that published a supplier CSV as products and variants in the client’s live Shopify store with zero failed imports. I fixed a concurrency race and updated theme templates so imported products were enquiry-only.
At IBM, I led a six-member team building news topic-modelling pipelines and a Streamlit dashboard. In project work, I developed a credential-isolated AI task agent and a satellite imagery pipeline for dam monitoring.
