What I work on

My day work is enterprise cloud and mobile architecture: Azure platform design, identity, and cross-platform apps built with .NET MAUI and Flutter, shipped to a global user base. Cloud work spans Azure, Google Cloud, and Firebase rather than a single provider.

More recently that has extended into applied AI — Azure AI, Claude, and GitHub Copilot inside real delivery workflows rather than demos: retrieval-augmented generation, agent patterns, and the developer-productivity side of AI assistance. Day to day that means C# and Python, APIs, and the DevOps to get it all shipped.

Why this blog exists

Across 500+ published articles the pattern that keeps recurring is this: the tutorial gets you to "hello world", then leaves before the hard part. This blog is the other half — the configuration that silently disables your security, the layout that stops scaling at twenty endpoints, the retrieval step that quietly decides whether your RAG system is any good.

Every post carries runnable code, the reasoning behind each choice, and an honest account of what breaks.

Community

Alongside writing, I have delivered 50+ conference sessions reaching 15,000+ developers, publishing in both English and Tamil so the material reaches people who are usually served last. Most of my community work sits at the point where cloud architecture meets people meeting it for the first time.

The contributions log is the dated record of that work.
