I build scalable full-stack applications and lead teams shipping reliable user-focused products.
South AfricaWhat I'm looking for
I've built and maintained full-stack applications for Online Education Services and Land and Sea Shipping, serving thousands of users through responsive web, mobile, and business platforms.
At OES, I build Svelte/SvelteKit interfaces, Node.js and TypeScript services, real-time notifications, reporting improvements, and GenAI-powered tools. I also improve testing, CI/CD workflows, Docker tooling, cross-browser reliability, and platform upgrades.
Previously, I led a team through React, Node.js, React Native, Next.js, Firebase, and REST API delivery, including ticketing and donation systems with QR validation and automated receipts. I enjoy clean code, new technology, difficult problems, and mentoring developers through better implementations.
