What I'm looking for

I'm open to remote roles aligned with US business hours where I can build secure, high-scale distributed platforms, lead architecture decisions, mentor engineers, and apply AI tooling to improve software delivery.

At Sensedia, I own the architecture of an Open Insurance platform serving 10+ insurance institutions and previously architected regulatory metrics reporting for 30+ financial institutions.

I've built AWS event-driven systems that sustain 30M+ daily and 1B+ monthly transactions while meeting a 24-hour regulatory SLA at 99.5% adherence. My work spans Java, Spring WebFlux, Kubernetes autoscaling, OAuth 2.0, OpenID Connect, FAPI 1.0 Advanced, mTLS, and observability.

Before Sensedia, I helped Saneago modernize legacy systems by decomposing a monolith into six independently deployable services, building REST APIs over IBM DB2, and standardizing delivery through GitLab CI.

I also mentor engineers, define architecture standards and ADRs, and drive AI adoption through spec-driven development and RAG-based tooling. I'm building SeguroHub and an Open Insurance MCP Server to make insurance data and regulatory knowledge more accessible.
