Emirhan Zengin Flutter Developer
I've been building mobile apps with Flutter professionally since 2022. At Demircode I built client apps from the ground up — architecture, API integration, UI and release — in B2B commerce, ERP, fintech, POS, logistics, travel and e-learning. More than twenty in all, until I left in October 2026. Before that, at Internative, I worked on WebRTC voice and video calling, including the telehealth app Elra Health.
I also work on my own products: an IPTV player, a logging backend in .NET, a QR platform for vehicles. When something turns out to be reusable, I publish it as an open-source package.
