I write code, I build circuits, and every now and then I look up at the sky and think.
Self-taught developer from Antalya, Turkey · crypto · automation · IoT · AI
I'm a self-taught developer who enjoys taking an idea and turning it into something real — whether that's a web app, a trading bot, or a circuit on my desk. My work spans web development, embedded systems & IoT, and Linux / DevOps. I write mostly Python and JavaScript, run everything in Docker, and love building things I can actually touch.

Hardware & mobile
- trvision — Streams my desktop to Thermalright Vision USB displays without the vendor's software, straight over WinUSB.
- videoplayer — Oynatıcı, an offline, plays-everything Android video player built on libVLC, with an AMOLED dark UI and gesture controls.
