JJ Jiles

Senior Front-End Developer & Architect

About

JJ Jiles has been a front-end developer since 1998, growing over more than 25 years from building early websites into a senior developer and architect specializing in UI/UX design and front-end architecture. JJ joined SEQTEK in 2012 and has since designed and built user interfaces for clients across industries ranging from oil and gas to data analysis. Angular is an everyday tool, and JJ is equally comfortable in React and Vue, choosing the right one for each project. The work covers the full front-end picture, from the design thinking behind an interface to the component architecture, styling systems, and state management that keep it maintainable for years. What makes the work meaningful is turning complex, data-heavy workflows into interfaces that people can use with confidence every day.
