About

I build small products and local AI workflows.

I’m Semih Mutlu, a Boğaziçi University CET student. I care about making useful things, showing the work, and being precise about what the evidence supports.

What I build

Movies Wrapped turns a Letterboxd export into a personal data story. TAP makes AI-tool spending visible from session history. My projects show the product, repository, and available proof.

How I work

I start with a problem I can inspect firsthand. I prototype quickly, use agents for repeatable work, and verify the result against the real system. At Madlen, that meant product QA, UX review, issue reporting, and retesting fixes.

What I’m learning

Lately I've been studying the foundations: system design and distributed systems. Next I want to learn how models are built and trained, not only how to use them.
