I am open to new opportunities
Hi, my name is
Deepak Kumar
AI Engineer & Full Stack Developer — designing intelligent systems with LLMs, Agentic AI, and RAG, shipped end-to-end from backend to cloud.
About Me
Full Stack Developer & AI Engineer
I'm Deepak Kumar — Full Stack Developer and AI Engineer with 5 years of experience building systems that are fast, scalable, and intelligent.
On the AI side, I design Agentic workflows, RAG pipelines, and fine-tuned LLMs using OpenAI, Anthropic, and LangChain. On the engineering side, I build robust backends in Python, Node.js, and Golang, modern frontends in React and Next.js, and deploy everything on AWS.
From LLM to cloud — backend, frontend, and everything in between. Open to AI Engineering, Full Stack, and Backend roles where the problems are hard and the work is ambitious.
