About Me

Building with precision,
designing with purpose

"The best software is invisible — it simply works, beautifully and reliably."

I am a Computer Science student at the University of Illinois Chicago, specializing in Software Engineering. Last summer I worked on the Generative AI R&D team at Ernst & Young — architecting structured datasets, benchmarking LLM outputs across GPT-4, Claude, and Llama, and contributing to measurable improvements in AI response quality for enterprise clients.

My strengths span full-stack development, intelligent system design, and data engineering. I approach every project with an engineer's rigour and a designer's sensibility — whether that means shipping a production-ready AI platform in 24 hours at a hackathon or optimizing GenAI pipelines across 15+ client use cases.

I am a collaborative, detail-oriented professional with a global perspective shaped by extensive international travel, and a genuine passion for technology that creates meaningful impact.

ChiMetrics — Chicago Civic Data Dashboard

A live civic data dashboard for Chicago, visualizing real-time public datasets across crime trends, CTA transit ridership, red light and speed camera violations, and 311 service requests — all sourced from the Chicago Open Data Portal. Grew out of an earlier C++ red light camera analysis tool, rebuilt as a full React application with interactive charts and live API integration.
