I'm Harish Rawal, a results-oriented Software Engineer with 3+ years of professional experience architecting scalable full-stack web applications, AI-powered workflows, and high-throughput backend services.

My day-to-day focus centers on TypeScript, Next.js, Node.js, Express, Python, FastAPI, PostgreSQL, and MongoDB. I specialize in designing robust RESTful APIs, implementing bulletproof authentication (JWT/RBAC), optimizing database indexing for low-latency queries, and automating cloud deployments with Docker and AWS.

Beyond core backend and web engineering, I build AI-powered workflows leveraging the OpenAI API, conversational streaming, RAG pipelines, and LLM integrations to solve practical problems for users and businesses.
