09 / 14

I like understanding the system, not just the ticket.

Engineering / Product

ANKARA / GMT+3

I've spent the last 3+ years building software across different parts of the stack, usually in projects where the problem is larger than a single interface or API. I enjoy understanding how the product works as a whole — who uses it, where complexity actually comes from, and what needs to remain simple.

My way of learning is mostly driven by building. When a project requires a technology I haven't used deeply before, I prefer understanding the underlying model, building something real with it, and then refining the implementation through use rather than collecting tools for the sake of a longer stack.

The problems I enjoy most sit between product and engineering: systems with real workflows, multiple roles, integrations, automation, data, AI or operational constraints. I care about shipping, but I also care about leaving behind code and architecture that can survive the next version.

Useful software first. Complexity only when it earns its place.
