What I'm looking for

I am looking for opportunities that allow me to grow, innovate, and contribute to impactful projects in a collaborative environment.

I'm a Front End Developer with over 4 years of experience in building modern, accessible, and scalable user interfaces. My specialization in React.js and adherence to web best practices, including WCAG and responsive design, have allowed me to lead the creation of corporate portals that significantly enhance user experience across multiple devices. One of my proudest achievements was reducing visual errors by 80%, showcasing my commitment to quality and user-centric design.

At Avature, I led the development and maintenance of accessible corporate portals, where I refactored critical components to improve scalability and load times by 30%. My collaborative work with UX and QA teams has been instrumental in driving accessibility improvements and ensuring compliance with WCAG 2.2. I pride myself on consistently delivering high-quality projects on time, with a strong focus on code quality and meeting deadlines.

As a freelance developer, I have built multiple responsive websites and SPAs for various clients, integrating RESTful APIs and optimizing data load times by up to 40%. My ability to manage the full project lifecycle, from GitHub to deployment, has ensured successful project delivery. I am currently seeking new opportunities to leverage my skills and continue growing in the field of front-end development.
