About me
Data Visualisation Engineer with a decade of professional TypeScript experience, building on React since 2016 and Next.js since 2018. On most projects I was the first frontend hire, owning architecture, tooling, and pipelines from day one and shipping product features end to end, then growing the team: hiring, interviewing, onboarding, and writing the playbooks that let new engineers integrate seamlessly. Most of that experience is in cybersecurity, building dashboards and proprietary data explorers, that's where I learned what separates a polished product from a prototype and found my passion for data-driven products and visualisations.
