Approach

How I Work

The difference between a prototype and a product is how you think, not just what you code.

Understand

Dig into the real problem. Most requests are symptoms. I find the root cause before writing a line.

Architect

Design the system before touching code. Data flow, failure modes, scalability: all mapped upfront.

Build

Ship working software fast. Iterate in small cycles. No gold-plating. Value delivered early.

Deploy

Production-grade from day one. CI/CD, monitoring, error handling: not an afterthought.

Scale

Performance tuning, team scaling, architecture evolution. Built to grow without breaking.

About

Builder.
Engineer.
Founder.

I'm an AI engineer who builds things that matter in production, not demos. My core strength is bridging the gap between cutting-edge AI and real business outcomes: fast, scalable, and deployed.

I'm currently a GenAI Engineer at Evolver (Palo Alto, remote), and have previously built production AI systems at Perfecter.ai and led data science work at Dexpro Innovations. I also hold stakes in BlackBox Learning and PRception.

Beyond writing code, I architect teams, lead cross-functional builds, and drive product strategy from ideation to deployment. If you're building something ambitious with AI, I want to hear about it.
