Solo Engineer // Kumbakonam, India

I build alone what most people need a team for.

Mechanical engineer turned full-stack and AI builder. Trading systems, applied AI, precision hardware — shipped solo, from Kumbakonam, India.

01 // THE BACKGROUND

Roots & Standards

Read Full Story

I started with gears and stress calculations, not code. Mechanical engineering taught me to design things that have to actually work — no room for hand-waving.

That's the standard I still build to. Today it's full-stack products, applied AI, and trading systems that run unattended with real money on the line. I ship solo, using AI tools as leverage, not as a crutch.

Tolerances over Hype

Physical engineering doesn't forgive bad assumptions. Software shouldn't either.

Solo Shipping Leverage

Disciplined architecture and modern AI tooling eliminate bloated coordination overhead.

Real Money Verification

Theoretical systems look great on paper. Real proof is unattended execution under stress.

02 // CAPABILITIES
