I'm a software and hardware developer with a hands-on approach to turning ideas into solid, scalable solutions. Over the past few years I built and shipped a plug-and-play smart home ecosystem (App4Home), prototyped hardware enclosures in CAD and 3D printed them, and defined a standard framework for product configurations. I enjoy end-to-end development across frontend, backend, databases, and API integrations, and I love simplifying complex tech into robust platforms that teams can maintain and extend. I’ve led projects across the stack, implemented automation and OTA update mechanisms, and integrated CRM and accounting software interfaces. My experience spans cloud-native tooling, API design, and cross-functional collaboration, with a focus on delivering reliable, scalable software in concert with hardware components.…I'm a software and hardware developer with a hands-on approach to turning ideas into solid, scalable solutions.
