What I'm looking for

I am looking for a role that fosters innovation, offers leadership opportunities, and encourages continuous learning.

With over 12 years of experience as a Staff Full Stack Developer, I specialize in building and optimizing innovative web applications. My expertise spans both frontend and backend technologies, allowing me to create scalable, efficient, and high-performing solutions. I have a proven track record of leading development teams through the complete software development lifecycle, consistently delivering applications that meet business goals and exceed user expectations.

In my most recent role at Altoros, I developed a scalable interactive video platform that improved load times by 40% and enhanced the mobile user experience for over 10,000 users. My commitment to performance optimization is evident in my work with React Native, where I successfully reduced initial load times by 30% for high-traffic mobile apps. I am passionate about mentoring junior developers and fostering a culture of innovation, which has resulted in a 15% improvement in team productivity.
