Hi there! I'm Tony Theintz, a software engineer based in Sion, Switzerland, with extensive experience as a freelancer and as CTO of Japort SA. I enjoy turning complex requirements into robust software solutions and helping teams optimize their processes while delivering value to customers. I thrive in autonomous roles and collaborative environments alike, and I’m always eager to learn and adapt to new tech stacks. I’m comfortable across the stack—from backend Java or PHP services to frontend JavaScript apps, containerized deployments with Docker, and cloud tooling. In my free time I mentor clients and take on independent projects, always aiming for clean code, practical architecture, and measurable impact.
