Open to senior mobile, web & full-stack roles

I build products that hold up under pressure — on phones and on the web.

Thousands of concurrent sockets, millions of property listings, payments that cannot afford to be wrong. For the past five years I've architected and shipped cross-platform apps for B2B and B2C markets, taking products the whole way from a Figma handoff to a live listing on the App Store and Google Play. Most of that work lives where mobile gets genuinely hard: real-time communication over WebRTC and Socket.IO, offline-first data layers, and payment flows that have to survive real money.

I work close to the metal when it pays off — React Native's New Architecture, TurboModules, Fabric and JSI, with native Swift and Kotlin modules when the bridge isn't enough. Lately that's meant folding LLMs into product surfaces and designing marketplace architectures with escrow and split payments. The same standards travel to the web: Next.js platforms with real-time bidding, threaded discussion and regional payment rails.

I own the full SDLC: architecture, implementation, release engineering, CI/CD and the store submissions nobody volunteers for. The result is software that ships on time and stays crash-free once it's out there.

Let’s build something great.

I’m open to senior mobile, web and full-stack roles, and selective consulting. If you have a product that needs to work across platforms and hold up under load, I’d like to hear about it.
