About.
A few things about me
I'm a software engineer who loves building products that people actually use. With 7+ years in the industry, I've shipped production features to thousands of users across global markets.
My expertise spans web and mobile development — from design system architecture and performance optimisation to end-to-end test automation and security hardening. I've led UI library migrations, built real-time chat systems, and orchestrated 20+ production releases across multiple engineering teams.
Currently at The Real Brokerage, I work across both web (React + TypeScript) and mobile (React Native) platforms. I'm passionate about AI-driven development workflows and building tools that make developers more productive.
When I'm not coding, you'll find me cycling, playing chess, or exploring the latest in AI and open source.
