About

Software Engineer with 4+ years of experience building production-ready software across frontend, backend, cloud, and mobile platforms. I enjoy solving engineering problems that involve scalable architectures, developer tools, cloud infrastructure, and AI-powered applications. Throughout my career, I've worked across startups and product companies, building products using React, Node.js, Flutter, TypeScript, Python, AWS, and modern cloud technologies. Most recently, I co-founded Polygram, where I designed and built an AI-powered software development platform including web applications, backend APIs, VS Code extensions, cloud infrastructure, authentication systems, billing, and AI integrations. Previously, I worked at CleverTap and OTPless, helping enterprise customers build production applications, SDK integrations, and scalable authentication and engagement solutions. I'm currently looking for Software Engineer opportunities where I can contribute to building high-quality products while continuing to grow as an engineer.
