JCAbout Jo
Creative, test-driven senior fullstack developer (frontend leaning) with 5 years of professional experience delivering high-performance, accessible (WCAG AA), and scalable UIs for data-heavy platforms. Expert in Vue, React, TypeScript, and modern frontend tooling. Skilled at translating complex requirements, large data sets and complex business logic into intuitive products.
My recent work in ESG involved developing fullstack features such as intuitive data visualisations, dashboards, complex tables and management portals. Highly capable of working independently or embedded in a remote team, with a proven record of sprint planning, mentoring, estimating accurately, and shipping pixel-perfect user interfaces (UIs) under pressure.
Ready to step into freelance engagements requiring ownership, trust, and reliable outcomes.
