What I'm looking for

I'm looking to contribute to innovative teams that value continuous learning, working on projects that use JavaScript, React, and Node while building practical, user-focused solutions.

I'm building responsive web pages as a freelance web developer, using current technologies and focusing on smooth, efficient user experiences.

After 13 years across logistics operations and customer service, I bring practical business perspective around deadlines, metrics, operational efficiency, and real user needs to my work in technology.

I've supported first-level management-system operations, including checkout and back-office systems, while solving customer problems directly. I also serve as a Google Arcade Facilitator, sharing technical knowledge and helping strengthen the developer community.

I'm continuing my Computer Science bachelor's degree and applying my discipline and drive to learn in full-stack development.
