Selim Saygı

Full stack software engineer who enjoys working through hard problems toward efficient, cost-effective solutions.

I work end to end — frontend, backend, and the bits in between. I like taking on challenging tasks and finding ways to solve them cleanly and efficiently, keeping things practical and cost-aware along the way. Engineer and father, happiest when the work is solid under the hood.

About

I'm a senior software engineer working across the full stack, currently at Trusted Shops. I've worked on a range of products from the UI down to the data layer. I tend to enjoy the more challenging tasks, and I try to solve them efficiently — leaning toward clean architecture, tight feedback loops, and solutions that stay cost-aware as they grow.

I lean heavily into AI-assisted development — using coding agents and LLM tooling to move faster, prototype quickly, and keep the focus on the hard parts of a problem.

Outside my day job, I build and ship my own apps and tools under Divided Bits, my independent software studio.
