About me
My name is Hunor (a.k.a. Hunzio) and I am a freelancer Software Engineer with 8+ years of professional work experience, based in Transylvania. I love working on full stack projects using different technologies. I put an emphasis on solid architecture and great design. When I'm not working, I can be found on the road, biking or in the mountains, hiking. Oh and watch out ... I am still learning drone piloting.
Skills
Projects
Smart Home solution for custom ESP32 based smart home devices (switches, sensors, etc.) with Google Home integration. Devices are connected to the system via the MQTT protocol. Users can manage their devices on a React-based UI. Device state changes are pushed to the UI realtime with Socket.io. Users can also control their devices with the Google Home app or Google Assistant.
Digital business cards connected to handcrafted wallets with built-in NFC tags. The idea is simple, just let someone scan your wallet with an NFC enabled phone and they can see your digital profile in their browser. It's a web-based solution, the NFC tags simply store the links to the profiles.
