About

Hi, I’m Hammad Ahmed, a full-stack engineer with applied AI capabilities, building large-scale applications using Cassandra and modern tech stacks like Node.js, React, Django, Docker, and AWS. I enjoy refactoring complex data models, delivering monetization and scheduling features, and authoring end-to-end documentation to ensure clear application behavior.

I’m currently developing a crisis-response AI chatbot with Rasa, Docker-based deployment, and plans for AWS hosting, while keeping production safety with feature toggles and real-time capabilities via WebSockets. I thrive in cross-functional teams and love turning challenging problems into scalable, maintainable solutions.
