Jun 2021 - Present • 5 yrs 3 mos

Worked on the development, maintenance, and improvement of production web applications in a long-term commercial environment. My responsibilities included implementing new features, fixing bugs, improving existing functionality, working with APIs, debugging application issues, maintaining existing codebases, and developing user-facing interfaces. I regularly worked with existing projects and code written by other developers, which required understanding established architecture, business logic, dependencies, and existing application behavior before implementing changes. I was responsible for investigating technical issues, identifying root causes, implementing reliable solutions, and making sure new changes did not negatively affect existing functionality. My experience includes working with responsive interfaces, forms, data processing, API integrations, application logic, reusable components, maintenance tasks, refactoring, and feature development. This long-term role gave me strong practical experience with real production software, including legacy code, changing requirements, debugging, maintenance, and continuous product development.
