I'm building Nautos, Martech Systems' flagship RAG platform, taking technical documentation from specification through vector embeddings to sub-second natural-language Q&A for engineering teams.

I've improved retrieval accuracy by benchmarking LLM output against precision and recall targets, refining chunking strategies, and selecting embedding models. I also built a GNN-based portfolio optimizer using more than five years of historical equity data across 50+ securities, validated against Sharpe ratio and maximum drawdown benchmarks.

My work also includes British Council-affiliated air-quality and economic-impact research, where I built Python pipelines and stakeholder-ready reports. I bring product thinking to technical work through SRS documentation, requirements definition, and data-driven decision-making.
