Building systems
that outlast the moment

I'm a Technical Architect based in Chennai with over 18 years of experience designing enterprise-grade systems across fintech, wealth management, and e-governance domains.

Today, my focus is on the intersection of AI and systems architecture — specifically building agentic AI systems that automate complex engineering workflows. I architected a multi-agent code review system on the Purple Fabric platform and built AI-driven tooling that transforms legacy codebases into modern microservices architectures.

Purple Fabric is an enterprise AI platform by Intellect Design Arena, used to build and orchestrate multi-agent business workflows.

I believe the next generation of enterprise software will be built by teams of AI agents orchestrated by architects who understand both systems design and the nuances of LLM behavior. That's the intersection I operate in.

Currently at Intellect Design Arena, leading AI-driven modernization for wealth and capital markets platforms. Also pursuing the AI Coder: Vibe Coder to Agentic Engineer course to deepen my agentic engineering expertise.
