Senior Frontend Developer
About me
Hi, I'm Jack. I'm a Senior Frontend Developer at Ocean Finance with just over 7 years of professional experience.
Rather than just building applications, I focus on engineering accessible customer journeys and technical solutions across our financial product range. I have established a standard for high-quality, readable code and a bit of a reputation for my love of refactoring - I'm a firm believer that high-quality, readable code is a gift to the next developer who has to touch it (whether that developer is me or someone else).
My work is centered on the Vue.js ecosystem, with a heavy emphasis on performance optimization, technical SEO, web accessibility (WCAG), and maintaining robust component libraries. Outside of work you'll likely find me building LEGO, tinkering with electronics/hardware/software, or following the latest in Formula 1, musical theatre, and theme parks.
