What I'm looking for

I’m looking for a senior role where I can lead modernization and microservices in .NET/Java, strengthen systems integration and reliability, and help clients achieve strategic outcomes—while mentoring teams.

I’m an experienced Senior Software Engineer and Senior Consultant who delivers innovative, scalable IT solutions to address complex business challenges. I specialize in modernization efforts, systems integration, and project coordination—leveraging deep technical expertise in software development to improve operations, reliability, and client satisfaction.

Across MEO, Link Consulting, and Banco Comercial Português, I’ve led technical teams and delivered major platform upgrades, including migrating legacy systems to current technologies (e.g., .NET 8 and modern enterprise standards), improving performance and stability, and reducing operational troubles and support tickets. I bring hands-on strength in microservices, REST/SOAP integrations, messaging (Kafka/Kafka/protobuf, IBM MQ, MSMQ), and production delivery with CI/CD, observability (Datadog), and cloud deployments on AWS.
