Notes

Write-ups from real projects: what broke, what worked, and the code.

All notes

  1. Headless Chrome won’t go below 500px wide: three fixes

    A 390px screenshot is a cropped 500px layout — and three ways to get a real narrow viewport.

  2. A Flutter offline sync queue on Hive CE, gaps included

    How queued writes are stored, ordered, retried and dropped — and what's left out.

Experience

From the first architecture decision to the next release. Taking ownership, every step of the way.

About

What I care about is boring releases: apps that stay fast, don't crash, and go out on a pipeline nobody has to babysit.

I'm a mobile engineer based in Istanbul. Since 2021 I've shipped cross-platform apps across car rental, B2B vehicle inspection and driver safety — often as the only mobile developer on the project, from architecture through store release.

I studied Software Engineering at Fırat University (2018–2023).
