What I'm looking for

I'm looking to contribute to an early-stage startup team, build secure and scalable backend features, and grow alongside the product.

I built production-grade REST APIs and full-stack features at PCS Global Pvt. Ltd., using Spring Boot and React.js for enterprise software in production.

I designed secure, scalable backend systems with JWT authentication, Spring Security, JPA/Hibernate, MongoDB, and MySQL. I also debugged performance bottlenecks to reduce latency in key API endpoints while collaborating through Agile sprints and code reviews.

Through AI Chemist, I built a RAG-based medicine assistant using Spring AI, Ollama Llama3, and MongoDB Atlas vector search, covering embeddings, semantic search, authentication, and role-based access.
