What I'm looking for

I’m looking for a Software Engineering role where I can build scalable backend systems in C++/Python, own architecture end-to-end, implement reliable testing, and contribute clear technical documentation in a supportive team.

I’m a Software Engineer based in Portugal, specializing in building high-performance real-time software in C++. I’ve owned the full backend development lifecycle—from architecture and implementation to testing, maintenance, and documentation.

I architected and introduced a clean, scalable approach for managing data across interconnected system components, improving maintainability and extensibility. I also implemented inter-component communication using Protocol Buffers (Protobuf), wrote comprehensive technical documentation, and acted as the go-to person for system details to support troubleshooting and onboarding.
