Product Builder · Berlin

Hi, I'm Serkan.

Product builder. With ❤️ from Berlin, Germany.

I usually describe myself as a product person with engineering roots. I started my professional journey as a software engineer, grew into an engineering leadership role, and eventually moved into product management — where I get to bring both worlds together: technical judgment and product instinct.

Outside of my day job, I like building small things for fun. One of them is CV Butler, a tool that runs an ATS review on your résumé, scores it against a job description, and writes you a cover letter. I also write about product and engineering on Medium.

Want the fuller story? Check out my resume, or just say hi.

CV Butler

Live

An ATS review for your résumé, a score against a specific job description — surfacing skill, experience, and education gaps — and a cover letter written for you, generic or tailored to the posting.

Started as a weekend project to scratch my own itch during a job search; the demo card on the right is a real piece of its UI.
