Hi, I'm Hammad Hassan
>
I build production backends in Java & Python and ship full-stack LLM, RAG and agentic AI applications on Azure and AWS.
01. About me
Backend engineer with an applied-AI edge
Software Engineer with nearly four years of building production backends in Java (Spring Boot) and Python (Django), across payments, authorisation, and scalable REST and GraphQL APIs. Recent work focuses on applied AI — shipping and deploying full-stack LLM, RAG, and agentic applications on Azure and AWS. I have also published a fully tested Java library to Maven Central and contributed to open-source projects.
Production backends
Java (Spring Boot) & Python (Django) — payments, authorisation, and scalable REST & GraphQL APIs across microservices.
Applied AI, shipped
Full-stack LLM, RAG and agentic applications with tool-calling — deployed on Azure and AWS.
Quality-first engineering
A 100%-tested Java library on Maven Central, CI/CD pipelines, and a 90%+ code-review acceptance rate.
Leads & collaborates
Led feature teams of 3–4 engineers, mentored contributors, and shipped client feedback in Agile/Scrum.
02. Skills & stack
What I build with
Backend-leaning full-stack, with deep recent focus on applied AI — from REST/GraphQL services to RAG pipelines and agentic systems.
