about

who I am & how I build

I'm Anshu Sharma, a Full-Stack AI Engineer & Agentic Systems Architect focused on building intelligent AI agent workflows, scalable cloud backends, and modern web applications.

I specialize in NestJS, Golang, Express.js, Python, Redis, PostgreSQL, AWS, NGINX, React.js, Next.js, alongside Agentic AI Frameworks (LangChain, LangGraph, DeepAgent), event-driven microservices (Kafka, Temporal), and cloud infrastructure.

My engineering approach bridges state-of-the-art AI automation with robust backend systems — creating intelligent, deterministic, and self-healing agentic workflows designed to solve complex real-world problems.
