🤩
RockstarGareth Parker is a Developer Coach based in Edinburgh with 12 years of engineering experience and a seven-year background in web development, specializing in PHP, MySQL and modern JavaScript ecosystems. He has led backend teams and driven migrations to microservices and TypeScript while improving performance—halving front-end load times at Brainnwave and increasing portal capacity through SSR and domain-driven design at Harness Property. Gareth combines hands-on implementation (APIs, front-end frameworks, web services) with mentoring and process overhaul, making him equally comfortable shipping features and growing developer capability. He is an active open-source contributor to the well-known Stryker-JS mutation testing project, where he added E2E and Jest-focused test runner features. Colleagues describe him as a perpetual learner who deliberately seeks new knowledge from peers to avoid stagnation and continuously evolve both craft and team practice.
