About

Turning ideas into software

I'm Nayeem, a software engineer who loves building fast, dependable systems - from enterprise .NET backends to intelligent AI-powered applications.

Over the last 5 years I've designed RESTful APIs, microservices and data pipelines. More recently I've been shipping LLM-powered features using Azure OpenAI, Semantic Kernel and LangChain.

I care about clean architecture, well-tested code, and products that feel effortless to use. When I'm not coding, I write about .NET and AI on my blog.
