I built Lucid, a multi-tenant analytics SaaS platform that answers questions from computed dataset statistics. I designed, built, and deployed its authentication, REST API, data-profiling and cleaning pipelines, and subscription tiers.

In my AI projects, I built a grounded document Q&A agent that cites source chunks and refuses questions it can’t answer from context. I also wrote an evaluation harness and fixed its keyword-matching logic, verifying a 6/6 pass rate.

I built a multi-tool LangGraph agent with input validation at each tool boundary, and an unattended monitoring pipeline that retries failures and reports reliability through a dashboard. I’m also building QuantGuard, a multi-agent trading-signal pipeline with a Gemini-based strategy parser.

Alongside AI engineering, I’ve built financial dashboards in Power BI for banking, crypto, and global markets, and connected PostgreSQL and MySQL databases to Power BI for live dashboards. I’m open to remote freelance and full-time AI engineering roles worldwide.
