    Hello! I'm Shreshth, a seasoned software engineer. I've worked at Amazon, Tesla, and Chewy on various projects. Now, I've launched my startup where I've already led 50+ digitization projects in Web & Mobile Applications (WordPress, React Native, React.js/Next.js, Node.js, Java). At Tesla, in a 4-week timeframe, I led a project to consolidate and revamp an application for 20,000+ weekly visitors across 25+ diverse locales, supporting translations including right-to-left (RTL). The application achieved 91% for accessibility and 100% for best practices and SEO as assessed by Google's Lighthouse report. At Chewy, I found, diagnosed, and resolved a critical micro-frontend load time issue by implementing incremental caching with Next.js and React.js. This led to a drastic 75% reduction in backend costs and compute consumption leading to at least a 300% improvement in page load time, improving customer satisfaction and system performance. My education stems from the University of Washington, where I've studied Computer Science and Data Science. I've learned and worked with Software Engineering, Deep Learning, Artificial Intelligence, Machine Learning, Data Structures, and Algorithm Design. This solid academic foundation, coupled with my experience, has empowered me to work on impactful projects. But it's not all about the tech for me. I've always been a team player, and my ability to communicate effectively and work collaboratively was recognized by an Associate Director at Chewy. They said, "Shreshth demonstrated a great level of curiosity, dove deep into the problems and projects that he was given and did an amazing job of communicating his progress and keeping me in the loop. He fit in well with the team and was a big asset." I'm excited to bring this same level of dedication, curiosity, and commitment to your project. Let's create something amazing together!
