What I'm looking for

I’m looking for a new challenge where I can grow personally and professionally, contribute to a forward-thinking team, and deepen my knowledge of artificial intelligence, especially in AI-driven applications.

At Cegid, I work on Nexus, an AI-first platform for building and running AI-native applications. I ship user-facing features across React and TypeScript frontends and Python APIs, including agent runtime, sessions, authentication, and evaluation.

Before Nexus, I developed and maintained software at Cegid - Valuekeep, Wave Solutions - Sistemas De Informação, Lda., and Kiwit Digital Solutions Lda. I also co-founded and developed NearUS, a location-based app for anonymous communication, and served as project manager for a mobile platform supporting emigrants through MECS.
