About

I started writing software professionally in 2008 and never really stopped shipping. This page is the longer version of how I got here.

The short career story

My first six years were at Ekol Gayrimenkul Değerleme, a real-estate valuation firm in Istanbul, where I built the company's core work-management platform - job assignment and tracking, staff performance measurement, commission calculation - as both a Windows desktop client and a web application over a shared backend. Six years on one product and its data model taught me more about maintainable software than any greenfield project could have.

From 2014 to 2017 I was a senior developer at Haliç University, where I built the payment infrastructure underpinning the university's systems - the start of a payments thread that runs through my whole career - along with exam, classroom and course-scheduling systems that turned timetabling into a data problem. Stints at OBASE (payment integrations, and my first exposure to blockchain) and CNR Holding (a data layer over years of trade-fair history) followed.

In 2013 I founded Modern Yazılım and ran it alongside full-time employment until 2019, when it became my main occupation. In 2025 I co-founded Modern Works Global Ltd in the UK to serve international clients. Across the portfolio: roughly 4,300 commits over 14 active repositories, every release shipped through CI/CD, and a hard rule that user-facing, semantic-versioned changelogs are not optional.
