About
An engineer who ships, not pitches.
I'm Özgür Işık. A senior software engineer based in Türkiye. I build production systems that hold up in the field — across every layer of the stack. Native mobile, web, data architecture, AI and e-commerce. Lately my focus is agentic AI, e-export and cross-border logistics infrastructure. I build systems that work in the real world, not in the lab.

Cosine similarity doesn't measure how 'semantically close' two pieces of text are. It measures the angle between two vectors in whatever coordinate system the model was trained to organize — proximity in that system, not in meaning. Two sentences with opposite meanings can land on nearly identical embeddings if they share vocabulary. Most RAG pipelines learn — two months into production — that what they thought was a retrieval problem is actually a chunking problem.

Have a project in mind?
I take on a small number of engagements each quarter — full-stack builds, mobile rescues, data-flow architecture, AI plumbing. If your problem sounds interesting, write.
