Hi, I'm

Hüseyin Kaya

Full-Stack Developer, Production System Software Engineer, R&D Engineer, Computer Vision & Signal Processing

I build production-grade software where the web meets the factory floor — from .NET, Angular & React applications and Oracle SQL data layers to computer-vision quality systems and FPGA designs.

About me

Engineering software that keeps production running

I'm a software engineer with an electrical & electronics engineering background, currently designing and developing production system software at Brisa Bridgestone Sabancı — one of Europe's largest tire manufacturers. I work with cross-functional teams to ship scalable, high-performance solutions and to improve the interfaces where software meets hardware.

My path started in R&D: at Step Teknoloji I built industrial IoT and embedded projects for companies like KORDSA, FIAT (TOFAŞ) and MİTAŞ — from FPGA-based sensing hardware to computer-vision quality systems. That mix of low-level hardware fluency and full-stack development is what I bring to every project.

I care about root-cause analysis, clean testable code and measurable results. Off the clock the same habits go into my lab notebook — software-defined radio, computer vision and whatever else is on the bench. You'll also find me gaming, painting watercolors or playing violin.

    A pixel clock that shows how much Claude I have left

    256 pixels were the easy part. The hard parts were an OAuth refresh that can lock you out of your own account, and a firmware whose app-lifetime rules had to be measured rather than read.

    Television here is still analog, and an SDR can watch it

    I set out to receive digital TV with a HackRF and spent two days proving that three of the four options were impossible, unavailable, or wider than my radio. What was left is the one everybody assumes is dead.

    Does that hand have a glove on?

    A glove-compliance monitor built from pretrained models only. The first design decision — never letting the glove take part in finding the hand — turned out to be the one that could not have been fixed later.

    Decoding my own LoRa node the hard way

    An ESP32 sends humidity over an EBYTE LoRa module. Reading it back off the air with a HackRF took two days longer than it should have — because one correct measurement answered a question I hadn't asked.
