Turning discussions
into software
that compounds.

I elicit requirements from conversations, then build the precise system that solves the right problem — not the obvious one. My emphasis is on efficient solutions designed for scale, where efficiency is never an afterthought.

AI at the intersection of "this shouldn't work" and "how is this so smooth."

I'm Hassan — a product engineer and consultant. I build production AI platforms, scalable backend systems, and resilient data pipelines for enterprise and high-growth organisations.

My work spans LLM-powered applications, RAG architectures, and cloud-native infrastructure with a focus on performance, cost efficiency, and maintainability. I take ownership from problem definition to deployment.

I studied Computer Science at the Institute of Business Administration. I hold a CCNA and Google Cybersecurity certification. When I'm not engineering, I'm following Formula 1, obsessing over cars, or taking something apart to figure out how it works.
