What I'm looking for

I am looking for a role that values innovation and collaboration, where I can leverage my skills in frontend development and contribute to impactful projects.

I am a Senior Frontend Developer with over 10 years of experience in building scalable and high-performance web applications. My expertise lies in using modern frameworks like React and TypeScript, focusing on component-driven development and accessibility. I have a proven track record of enhancing user experience and performance in complex products, ensuring that my work not only meets but exceeds user expectations.

Throughout my career, I have successfully led teams and projects that have significantly improved application performance and user workflows. For instance, at Propelus, I implemented AI-driven features that reduced credit reporting time by nearly 50%. My commitment to quality is evident in my meticulous approach to testing and performance optimization, ensuring that every application I work on is robust and user-friendly.
