How I think

Engineering with a pulse.

01

Make it resilient

Reliable systems are designed before the traffic arrives. Failure modes, observability and recovery belong in the blueprint.

02

Keep it legible

Good software is easy to reason about. I value focused architecture, clear ownership and pragmatic abstractions.

03

Use AI deliberately

I use AI heavily, without outsourcing judgment. The goal is stronger engineering — not more generated noise.

The origin story

I started building for the web at fifteen. I never really stopped.

What began as websites with a friend grew into custom business software, connected lighting systems and payment infrastructure. I like the point where product thinking meets the machinery underneath — where an elegant interface still needs a system you can trust.

Today I combine backend engineering, infrastructure and data thinking to ship products that are useful, maintainable and ready to scale.
