About Me

Mehedi Hasan
Enterprise & AI Ready

I specialize in designing and engineering high-throughput backend APIs, microservice message architectures, and intelligent AI-augmented solutions. From architecting core banking modules with e-KYC and Nagad integrations to developing automated HR databases with millions of rows, I combine robust .NET engineering with modern AI agentic workflows.

My approach bridges the gap between enterprise software reliability and cutting-edge AI capabilities: implementing Retrieval-Augmented Generation (RAG), Semantic Kernel in .NET, function-calling agents, vector database embeddings, and asynchronous message queues to build dependable, production-grade applications.
