United StatesWhat I'm looking for
I am a seasoned software developer with over a decade of experience, primarily at Yahoo, where I honed my skills in frontend development using React. My journey has been marked by a commitment to innovation and a passion for creating efficient, user-friendly applications. I have successfully led projects that not only improved user experience but also optimized performance, achieving significant rendering speed improvements.
Throughout my career, I have demonstrated my ability to tackle complex challenges, such as building a fullstack content management system for a non-profit organization, which has become a leading database solution nationwide.

I thrive in collaborative environments, mentoring junior developers and managing Agile teams to deliver high-quality software solutions.
