At LYBL Healthtech Pvt. Ltd., I built an AI medical-assessment backend using LangChain4j and Claude Sonnet to interpret symptoms and reports, retrieve condition knowledge from Qdrant, and generate structured outputs for care-plan mapping.

I also engineered Stripe subscription and payment workflows, and designed Kafka-driven notifications. Previously, at Bytish IT Services Pvt. Ltd., I architected checkout and order-management flows and built transactional inventory reservation.
