Hello, I’m a Full-Stack Developer with 8 years of experience — 3+ years of hands-on development leadership and 3 years of designing scalable software architectures. I specialise in building cross-platform, high-performance applications using modern JavaScript frameworks and cloud-native infrastructure. In 2021, I founded ONE-FRONT and santeJS — initiatives created to align business goals, developer practices, and user needs. I focus on pragmatic engineering, clean architecture, and meaningful outcomes.

Thanks to his previous experience he seems also very resourceful and during the testing sessions I noticed that he would use his IT knowledge to overcome unexpected challenges that other users would have needed support for. Michael seemed highly motivated and eager to understand the company’s functioning both on high level as in process detail level.
