About

Hi, I’m Hamdi Ben Kahla, a software engineer focused on full‑stack development and Web3. I enjoy turning complex requirements into scalable architectures, shipping robust APIs, secure authentication flows, and delightful user interfaces. I’m passionate about blending traditional software with decentralized technologies to build practical, impact-driven products.

Based in Lisbon, I’m currently contributing to Youmio Launchpad, while drawing on experience from startups and consulting roles across Tunisia and Portugal. I love experimenting with cloud infrastructure, DevOps practices, and open‑source tooling, and I’m always eager to mentor others and learn new technologies.
