About Me
I'm a Software Engineer working across web, mobile, and AI-powered systems, with a strong focus on building scalable, production-ready products. I specialise in turning complex product ideas into reliable, maintainable software — combining modern frontend development with automation, AI integrations, and clean architecture. My work spans high-performance websites, mobile applications, and AI-driven workflows designed for real-world business use.
Recently, I've been working closely with Rubica as a contract Software Engineer, contributing to the launch of their platform by leading the website build, performance optimisation, UX improvements, and production readiness (SEO, structure, and reliability). I enjoy collaborating directly with founders, product leaders, and stakeholders to deliver practical solutions that scale.
My core stack includes React, Next.js, Flutter, and cloud-based automation tools, with a growing emphasis on AI integrations, workflow orchestration, and system design that follows modern best practices. I'm particularly interested in long-term, product-focused work where engineering quality, performance, and real user impact matter.
