I designed Netless UPI, a Spring Boot backend for offline payment settlement, with idempotent processing to handle concurrent duplicate deliveries. I used atomic compare-and-set operations to resolve race conditions and validated the behavior with concurrent JUnit tests.

For Netless UPI, I also applied RSA-OAEP and AES-256-GCM encryption to protect payment payloads. On my Euclid AI project, I built a C++ vector database with HNSW and KD-Tree search, then added a RAG pipeline using local LLMs.

At InternSpark, I built and maintained responsive React and Tailwind CSS components for core user flows, working with the design team in an iterative Agile workflow. I’ve also contributed through reviewed pull requests to Bitcoin Core and React-focused open-source repositories.
