À propos

Introduction

I turn complex ideas into real, working systems. With over 15 years in R&D, software engineering, and system design, I’ve built and led multidisciplinary teams to deliver reliable, scalable platforms, from embedded systems to large-scale cloud architectures. I combine deep technical expertise with a pragmatic, hands-on mindset and the ability to bridge disciplines. From architecture to product delivery, I adapt quickly, connect teams, and make things happen.

I joined myDevices to continue the journey initiated with WebIOPi, by contributing to Cayenne, the world’s first drag‑and‑drop IoT project builder. Over time, Cayenne evolved into the foundation of IoTinaBox, a fully packaged, plug‑and‑play IoT solution tailored for commercial deployments. I was deeply involved in this transition, from prototyping and core architecture to customer-facing features, helping create one of the easiest and most complete IoT deployment tools on the market. My work spanned architecture, development, and strategic input across multiple layers of the platform: • Collaborated daily with cross-continental teams on large-scale IoT deployments. • Provided deep expertise in network and telecom protocols, especially LoRaWAN, CoAP, MQTT, and HTTP. • Designed and implemented critical software components across the stack (front-end and back-end) using Node.js, Python, and modern cloud architecture patterns. • Acted as a technical liaison between Engineering, Product, and Business teams, ensuring strong alignment between market needs and technical capabilities. • Delivered internal trainings and knowledge-sharing sessions on connectivity, architecture, and tooling. • Contributed to pre-sales and post-sales support, translating technical solutions into business value. • Played a key role in product and architectural decision-making, shaping the platform’s long-term vision.
