I write code, I run engineering teams, and I chase quantum ideas. The thread through it all: designing systems that people and businesses rely on, and leading the engineers who keep them up every day.

About

Still a coder.
Now also the manager, the architect, the researcher.

My first real job was writing C# from our Bangalore office, and it was serious from day one: live systems, real deadlines, no room for guesswork. Over nineteen years I kept moving closer to the same question: how do you run important systems without breaking them?

The work today answers it from both sides. As a manager, I lead an engineering team spread across several countries. As the principal architect, I design the path that brings the most demanding clients, in finance and healthcare, onto the platform. In between, I have written the solution tutorials that developers still follow today, and designed the landing zones that banks and finance-software companies start from. And no, I haven't given up coding.

Off the clock, I am a student again. Quantum computing pulls me the hardest: I attended the Quantum Ideas Summer School and earned a certificate in quantum-safe cryptography. AI agents and plain old math keep me curious too, and math is my focus for 2026. More than 200 articles on all of this have reached a million-plus readers. I judge use cases for the watsonx challenge, and I run BlueCoders, a meetup community I started. People are kind about the awards: BCS Fellow, Distinguished Architect, the first Microsoft MVP for Games from India. But honestly? The best part is still the moment your code works.

Constrained Decoding Models Explained: Encoders, Decoders and When to Use Them

A constrained decoding model is a normal decoder LLM with a rule engine attached — the engine blocks every word piece that would break your schema, so the output always parses, but valid is not the same as right.
