Piyush Kumar

I am a Full-Stack Software Engineer (SDE-2) specializing in building scalable, AI-powered web applications and high-performance backend systems. I develop end-to-end solutions using React, Next.js, Node.js, Spring Boot, and modern databases like PostgreSQL, MongoDB, and Redis. I have strong expertise in designing secure authentication systems, implementing role-based access control, optimizing APIs with caching layers, and building Elasticsearch-powered search systems with low latency. I also build AI-driven workflows and LLM-based applications, including multilingual chat interfaces, automation pipelines, and intelligent business tools with high reliability. From system architecture and database design to deployment with Docker, CI/CD, and AWS, I help startups and businesses build fast, scalable, and production-ready software that solves real business problems and drives measurable growth.
