What I'm looking for

I’m looking for a product-focused team where I can own system architecture and distributed backend infrastructure on AWS, deliver measurable business value, and combine backend expertise with AI orchestration and LLM integration to accelerate development.

I’m a product-driven Software Engineer with 12+ years of experience transforming complex business requirements into scalable, high-value digital products. I specialize in system architecture, distributed systems, full stack development, and AWS cloud infrastructure—especially designing hyper-scale backend infrastructure that can absorb massive traffic bursts during global events.

At ODD Bureau in Coimbra, I progressed through increasingly senior technical roles over a 10-year tenure, architecting backend infrastructure and cloud deployments for high-impact platforms. I’ve built provider-agnostic e-signature frameworks automating contract execution, delivered decoupled enterprise ERP-style portals, and designed event-driven data pipelines that contributed to £51M+ in high-ticket sales, while processing 1,400+ aircraft orders and handling 100M+ votes and 500M+ requests during peak demand.
