AI / Full-stack engineer — Berlin

Hamza Malik

I build AI systems that hold up in production — retrieval that stays grounded, pipelines that run unattended, and inference fast enough to ship on the edge.

About

I'm an AI application engineer in Berlin, finishing an M.Sc. in Artificial Intelligence at BTU Cottbus. Most of my work sits where machine learning meets the rest of the system: pipelines, APIs, and the interfaces people actually touch.

Before AI I spent three years shipping commerce frontends and payment infrastructure, which is where I learned that reliability is a design problem as much as an engineering one.

Case study — real-time ML
Real-time beat & tempo tracking
Replaced particle filtering with a learned temporal model — a causal TemporalConvNet holding an F-measure of 0.82 while cutting inference from 200ms to 2ms and the memory footprint to under 10MB.
