I've built production backend systems for CareCloud MTBC, Air University, PrimeStack Sol, SparkoSol, and Ufone 4G across healthcare, telecom, and academic products.

At CareCloud MTBC, I build and maintain healthcare backend services with .NET Core, Spring Boot, and Golang, including REST APIs, OAuth 2.0 authentication, Redis caching, Azure integration, and microservice-based architecture.

I designed and delivered systems using Go, Node.js, Java, and C#/.NET, with PostgreSQL, MongoDB, Redis, DynamoDB, AWS, GCP, Docker, Kubernetes, and event-driven patterns. For SparkoSol, I improved API response time by 30% through JWT authentication and Redis caching.

I won first prize at TECHXHIBIT’25 for Med Chain Financial Care, an enterprise healthcare insurance prototype built with Hyperledger Fabric for blockchain-based claims processing and secure ledger workflows. I'm also building AI-integrated backend architectures with RAG, LangChain, LangSmith, vector databases, and retrieval-based enterprise applications.
