As a seasoned software engineer with over 10 years of experience, I have honed my skills in designing and building responsive and scalable web and mobile applications. My strong foundation in development fundamentals, combined with my extensive knowledge of UX and user psychology, allows me to create intuitive user experiences. I am passionate about clean and scalable code, and I advocate for testing at all levels to ensure high-quality deliverables.

Throughout my career, I have worked with various frameworks and libraries, including ReactJS, TypeScript, and React Native, among others. My recent roles as a Senior Software Engineer have involved leading teams, driving product development from conception to deployment, and mentoring junior developers. I thrive in fast-paced environments and am dedicated to improving the developer experience while maintaining the highest standards for code quality.
