WEB DEVELOPER

Summary

Full-stack-leaning web developer with considerable experience in WordPress and custom theme/plugin development. I build fast, responsive interfaces and translate designs into clean, maintainable code. I’m used to stepping into existing projects, identifying and resolving issues, and improving performance where it matters. I care about UX and code quality, and can work across front-end and server-side tasks as the project requires.
