About

I build enterprise-grade AI, data, and platform products that transform complex operational challenges into reliable and scalable software.

My work focuses on the intersection of:

  • Enterprise AI platforms and local LLM infrastructure
  • AI gateways, model routing, agents, and developer experience
  • Data products, Text2SQL, metadata, and analytics platforms
  • Kubernetes operations, DevSecOps, observability, and FinOps
  • FinTech workflows and business process automation

I enjoy building practical systems that connect technology, operations, governance, and business value.

Current Focus

Area What I am building
Enterprise AI Local LLM platforms, AI gateways, model routers, agents, and secure AI operations

Engineering Principles

Build for real operations.
Automate repetitive decisions.
Design security and governance from the beginning.
Prefer measurable outcomes over impressive demos.
Turn prototypes into maintainable products.
