Full Stack Software Engineer
I build fast, scalable, and beautiful software — from resilient event-driven backends to polished React frontends. Based in South Africa, working globally.
Who I Am
About Me
I'm a results-oriented Full Stack Software Engineer with 5+ years of experience building secure, scalable platforms. I specialise in Node.js, TypeScript, React, and cloud architecture on AWS.
Most recently at Nagging Panda, I served as a core developer on a multi-tenant B2B SaaS platform for accounts receivable automation — where I implemented Event-Driven Architecture with BullMQ & Redis, achieved an 83% reduction in processing time by eliminating N+1 queries, and integrated Google Generative AI.
I'm based in Somerset West, South Africa and eager to bring high-impact engineering to dynamic, high-growth environments.
