As a Senior Software Engineer with over 10 years of experience, I deliver scalable, high-performance web applications using JavaScript, TypeScript, React, Next.js, Node.js, Express, Ruby on Rails, Python, Django, and databases like MySQL, PostgreSQL, and MongoDB. At a Stealth Startup, I re-architected a multi-page app into a single-page application, boosting user experience and page speed by 11%. I ensure 90%+ unit test coverage with Jest and implement CI/CD pipelines for reliable delivery. Let me build your end-to-end web solution with Agile methodologies, optimized code, and a focus on quality, scalability, and seamless functionality.
