Stack Developer Engineer

Sai Bhargav Sankoji

Full Stack Developer - Performance Developer

*******.***********@*****.*** 347-***-**** Pittsburgh, PA LinkedIn PROFESSIONAL SUMMARY

Highly motivated Full Stack Engineer with over 5 years of experience, specializing in Next.js, React.js, and TypeScript. Proven expertise in frontend development, documentation, and developer experience (DX), focusing on creating interactive and performance-optimized web applications. Strong advocate for technical writing and creating tutorials that simplify complex technical concepts for broader audiences. Seeking to leverage my skills to maintain and enhance Next.js documentation at Vercel, fostering a global community of developers by providing clear, actionable content and examples. Analyzed frontend and backend performance bottlenecks with an emphasis on memory optimization, rendering efficiency, and execution speed, resulting in more stable applications. Through benchmarking React reconciliation, I reduced re-renders by 40%, and by implementing tree-shaking and lazy loading, I cut bundle sizes by 50%. I leveraged V8 engine optimizations (hidden classes, inline caching, deoptimization) to boost JavaScript execution and used Chrome DevTools, Lighthouse, React Profiler, and WebPageTest to significantly enhance load times and responsiveness in large-scale deployments. Additionally, I developed proof-of-concept projects and authored technical articles, increasing developer engagement by 50%, while advancing Next.js static generation, hybrid rendering, and API response times to deliver scalable, high-performance web applications.
