What I'm looking for

I’m looking to build scalable, user-centric web applications with clean-code practices and a focus on accessibility—while continuing to communicate technical ideas clearly, mentor others, and collaborate with teams that value thoughtful UX.

I’m a versatile full-stack developer and technical educator who loves building scalable web applications and turning complex code into something people can confidently use. I bring clean-code engineering and user-centric design together to create seamless digital experiences, backed by strong experience teaching and writing technical content.

In my recent roles, I’ve taught live and asynchronous Python-based coding instruction, supported students through weekly office hours, and helped sustain engagement through newsletters and demo nights. As a full-stack developer, I redesigned WordPress websites, improved open-source documentation with written articles, and built responsive applications with JavaScript, React, Node.js, Express, and MongoDB—cutting loading times by 5% through refactoring and performance tuning.
