What I'm looking for

I'm seeking an IT consulting role where my broad technical range and fast ramp-up can deliver real client value.

At Sierra Bravo Intelligence, I developed Tunipadel, a padel platform with court booking, real-time matchmaking, tournaments, notifications, and an admin dashboard. I built REST APIs and WebSocket services for live updates, messaging, and matchmaking, then deployed the platform on a VPS using Docker.

At IT-BAFA, I developed PSMP, a transport platform for booking, carpooling, and cargo, using Flutter and a Spring Boot backend. Earlier, at Lab 619, I built a Flutter app for IoT device control and connected an Arduino/ESP32 sensor node to an MQTT and Node.js/MongoDB backend. I’m seeking an IT consulting role where my broad technical range and fast ramp-up can deliver real client value.
