Embedded Software Engineer at BELBİM building fare-collection systems processing 20M+ daily transactions.

What I'm looking for

I'm open to relocation across the EU and eligible for the EU Blue Card and the Netherlands highly skilled migrant scheme. I require employer sponsorship.

At BELBİM Electronic Money and Payment Services Inc., I develop C++ software for Istanbul’s fare-collection validators, which handle more than 20 million passenger transactions a day. I extended the platform to accept EMV contactless bank cards and built a firmware distribution chain that updates more than 4,000 field devices.

I also built payment and access-control products across device software, .NET services, databases, and operator dashboards. Earlier, I developed bare-metal firmware and electronics, including an infusion syringe pump with 1 µL/min dosing precision; more recently, I shipped Midiboard, an iOS Bluetooth MIDI controller, and three native macOS utilities.
