Available now — open to data analyst & product internships.
Hi, I'mBerke Zerelgil.
Mathematics & CS Student · Aspiring Product Manager — Math, data, and team leadership — on the road from data analyst to product manager.
I'm a final-year Mathematics & Computer Science student at Osmangazi University. Over the last two years I've led a 100-member technology club, digitized the operations of a traditional Turkish company, and mentored students through an AI club. My plan is the long game: start in data analysis to sharpen my number sense, grow into product ownership, and become the kind of product manager who can both read the spreadsheet and ship the roadmap.
I'm a fourth-year Mathematics & Computer Science student at Osmangazi University. Outside of class, I lead MACS Club (100+ members) and run digital transformation projects for a traditional Turkish company — turning paper-based workflows into tools people actually open every day.
My plan is the long game: start in data analytics to ground every decision in numbers, grow into product ownership, and become the kind of PM who can both read the spreadsheet and ship the roadmap.
Math as a decision tool
Statistics, probability, and a stubborn habit of asking 'what does the data actually say?' — the foundation I want to bring to every product decision I make.
Data-first product thinking
I'm starting in data analytics on purpose. Before owning a roadmap, I want to be the person in the room who can read the dashboard and ask the right next question.
Operator at heart
Whether it's digitizing a family business or running a 100-member club, I've spent the last two years learning how teams actually ship — requirements, cadence, follow-through.
The long game
Data analyst → product owner → product manager. I'm not in a rush for the title — I'm in a rush to be useful, and I'm building the foundation that compounds.
02 — Toolkit
The tools I think with.
I'm comfortable across the stack, but I'm a believer in depth. These are the tools I keep returning to — and the ones I'd pick if I had to ship something tonight.
A mix of research prototypes, shipped products, and weekend experiments. Each one taught me something I couldn't have learned from a book.
