From Commerce Student ➜ Self-Taught Developer ➜ Senior Engineer Delivering High-Impact UI & Growth Experiments Hi, I’m Amit Kumar Singh — a self-taught software engineer with 4+ years of experience building high-performance, conversion-focused web applications used by global brands. My journey started very differently. I come from a commerce background, studied BBA and MBA because that was the safest option I had at that time, and I had no mentor to guide me toward tech. But during college, I discovered programming, got curious, and decided to teach myself everything from scratch — React, JavaScript, Node.js, system design, and eventually full-stack development. From there, everything changed. I’ve since worked with multiple product companies and fast-growing startups, where I’ve designed and built large-scale experimentation systems (A/B & MVT), optimized critical user journeys, and improved key business metrics using React, Redux, TypeScript, and Optimizely. My work has consistently delivered measurable results, including: 6–8% uplift in conversions through data-driven A/B experiments 40% faster development cycles by creating reusable frontend architecture 25% improvement in performance across SPAs through deep optimization 30% more accurate analytics via real-time tracking integrations Across earlier roles, I contributed to rebuilding complex frontend systems, improving UX at scale, modernizing legacy codebases, and developing performance-focused dashboards using React, Vue, and serverless technologies. Beyond work, I enjoy building products, exploring AI/LLMs, improving UI/UX flows, and sharing my journey to inspire others who want to transition into tech without a CS degree. My story is simple — if you are hungry to learn, disciplined, and consistent, you can change your life through tech. And I’m here to help people make that shift.
