Message

At Deloitte USI, I built scalable React enterprise applications and integrated Python/FastAPI services. I replaced legacy REST endpoints with custom GraphQL queries, decreasing data retrieval latency by 15–20% and eliminating over-fetching.

I also engineered the frontend architecture for an Angular AI chatbot for a healthcare client, integrating NLP APIs that let medical personnel query databases in natural language. The work earned me Deloitte's Applause Award for rapid delivery; outside work, I built CodeScanner, a browser-based static code analysis and architecture visualization interface.
