Full Stack Engineer · Backend (Python, Java)
Python and Java services, React/TypeScript front ends, and transaction-safe APIs.
Software engineer with 3+ years at Airbnb and Accenture. I build REST APIs in FastAPI, Django and Spring Boot, front ends in React and TypeScript, and the parts that keep them correct under load: idempotent writes, input validation, JWT/OAuth2, rate limiting and query tuning. I also add LLM features that cite their sources.
