when it matters.

Full-stack TypeScript engineer and CISO building secure payment products that stay calm under pressure.

Selected work

Products and infrastructure where clear behavior matters as much as technical depth.

// typed payments, without the guesswork

About

Engineering judgment across products, security, and the moments when software meets real operations.

Product engineering

Full-stack TypeScript work from interface to infrastructure, with each layer designed as part of the same product.

Security leadership

As CISO at NFCtron, I integrate security into delivery instead of treating it as a review at the end.

Payments and operations

I build software for event-day pressure, where payment flows must stay clear and dependable when the venue gets busy.

Let's make it real.
