I've built scalable backend and full-stack platforms at CrystalTech Services, including e-Suchi/Samastha, a government healthcare system supporting patient registration, immunization tracking, offline synchronization, and state-level reporting.
I develop Ruby on Rails and Python services, integrate legacy systems and third-party APIs, and improve production reliability through Redis caching, Sidekiq, CI/CD, Docker, AWS, and performance monitoring. I've also delivered food-ordering, restaurant-management, and financial analytics products, while building AI features with OpenAI, Gemini, Claude, RAG pipelines, embeddings, and vector databases.
