Summary
👤
Senior🎓
Top SchoolAndrew Margetts is a founding engineer and security-focused full-stack leader with 10+ years building scalable, production-grade systems across crypto, IoT, and enterprise software. He has taken platforms from zero to one—most recently architecting Banter Challenges with deep exchange integrations and a modular Vue.js/Laravel/TypeScript stack—while splitting time between hands-on coding and leading engineering and AI teams. Known for blending pragmatic DevOps, penetration testing, and performance-driven middleware rewrites, he has repeatedly delivered large performance improvements (100–300%+) and measurable product gains like doubling conversion through A/B experimentation. He advises green-tech IoT projects on sustainable deployments and has a track record of embedding security as a first-class design principle rather than an afterthought. Based in Gauteng, South Africa, he pairs entrepreneurial strategy and startup consulting with a restless appetite for side projects, mountain biking, and learning.
