I build full-stack web and mobile applications with React, Next.js, Node.js, and Laravel.

I've built and maintained full-stack web applications at Signifi Media since 2021, delivering 2–3 end-to-end web projects annually using Next.js, React, Node.js, TypeScript, Tailwind CSS, Supabase, and Vercel.

I develop cross-platform mobile apps with REST API integrations, secure SMS/email authentication, user matching, and real-time data features. I've also built WordPress plugins, Shopify Plus checkout customisations, modular banner systems, and analytics integrations for Google Ads, HubSpot, and Loopa Automate.

Previously at Ad Impact, I helped build an internal project and client management system, led and mentored an offshore development team, and delivered WordPress and Concrete5 solutions with payment gateway integrations. I enjoy building modular, maintainable systems from architecture and database design through deployment and support.
