Engineer • Builder • Startup-minded

I build useful software for real people, not just demos.

I’m Tejas — a TS/SCI-cleared software engineer turning ambiguous ideas into shipped products. I work across backend systems, AI workflows, and product execution.

About me

I thrive in high-stakes, fast-moving environments where ownership matters. In my day job, I help modernize mission-critical systems. Outside work, I’m focused on building products, leveling up as a founder-minded engineer, and designing a life around discipline, health, and long-term financial freedom.

Trusted in High-Stakes Environments

Deliver software for mission-critical programs where reliability, speed, and accountability all matter at once.

From Ambiguity to Shipped Outcomes

Translate fuzzy requirements into clear architecture, execution plans, and production-ready delivery.

Lead Through Ownership

Drive cross-functional alignment, mentor teammates, and keep projects moving without waiting for perfect conditions.

Product-Minded Engineering

Balance technical rigor with user impact and business priorities so work ships and gets adopted.

What I’m focused on now

Operating principles

Clarity over complexityShip fast, then hardenOwn outcomes, not tasksUse AI as leverage, not a crutch
