about me

👋 Hi, I'm Lucas

Senior Backend Engineer · Distributed Systems, AWS, Microservices · Banking, Fintech & Telecom
Scaling secure platforms to millions & modernizing legacy at speed · Capgemini

Companies in banking, fintech, and telecom rely on scalable, secure systems to serve millions of users — especially when modernizing legacy platforms without disrupting business.

I help these organizations design and build cloud-native backend systems that improve reliability, accelerate delivery, and reduce operational complexity.

With 10+ years of experience, I've worked on high-scale platforms used by up to 55M+ users, leading migrations from monoliths to microservices, implementing cloud architectures (AWS), and driving engineering best practices across teams.

My work consistently focuses on measurable impact — from increasing system performance and scalability, to reducing cloud costs, improving code quality, and enabling faster, safer releases through CI/CD and automation.

I also collaborate closely with engineers and stakeholders, mentoring teams and helping create environments where good architecture, clean code, and continuous improvement are part of the culture, not just goals.

If you're building or evolving high-scale platforms and need reliable, well-architected systems that can grow with your business — let's connect.
