Available to hire
I’m Kuldeep Singh, a Senior React & Full Stack Developer with 6+ years of delivering secure, scalable web applications across telecommunications, healthcare, eCommerce, and traffic systems. I thrive on building fast, accessible user interfaces with React, robust APIs with Node.js, and well-architected cloud deployments on AWS. I enjoy collaborating in Agile teams and mentoring others to ship high-quality code.
From greenfield features to performance optimizations, I design solutions that improve reliability and customer experience. My toolkit includes React.js, TypeScript, GraphQL, PostgreSQL/MySQL, and AWS, plus CI/CD pipelines and micro-frontend architectures like Single-SPA. I’m always eager to learn new technologies and apply best practices in secure software development.
