Solutions Architect · Staff Engineer · Cloud & Distributed Systems
I design scalable, resilient, business-aligned architectures. My path runs from help desk and datacenter operations to leading Cloud Ops teams and, since 2021, Senior Solutions Architect at Itaú Unibanco, where I drive modernization, architectural governance and secure delivery across LATAM units.
On GitHub I keep a hands-on lab: ThinkLab, a platform of reactive microservices modeled after the BIAN (Banking Industry Architecture Network) service domains, plus automation and data tooling for my home lab.
- ThinkLab Platform — Java 21 + Micronaut 4 + Project Reactor microservices using hexagonal architecture, DDD and BIAN behavior qualifiers (
initiate,retrieve,update,control). - Observability & reliability — OpenTelemetry / W3C Trace Context, reactive MDC bridging and SRE forensics.
- Secure by default — distroless non-root images, read-only filesystems, AOT builds and Kubernetes / OpenShift manifests.
- AI-assisted engineering — building software and multi-agent workflows with Anthropic's Claude and prompt engineering.
Every service uses Java 21, Micronaut 4, Project Reactor, hexagonal architecture, ADRs and distroless non-root images.

Projeto arquiteturas escaláveis, resilientes e alinhadas ao negócio. Minha trajetória vai do help desk e operação de datacenter à liderança de times de Cloud Ops e, desde 2021, Arquiteto de Soluções Sênior no Itaú Unibanco, onde conduzo modernização, governança arquitetural e entrega segura em unidades da América Latina.
Aqui no GitHub mantenho um laboratório prático: ThinkLab, uma plataforma de microsserviços reativos modelada a partir dos service domains do BIAN (Banking Industry Architecture Network), além de ferramentas de automação e dados para o meu home lab.
- Plataforma ThinkLab — microsserviços em Java 21 + Micronaut 4 + Project Reactor com arquitetura hexagonal, DDD e behavior qualifiers do BIAN (
initiate,retrieve,update,control). - Observabilidade e confiabilidade — OpenTelemetry / W3C Trace Context, propagação de MDC em fluxos reativos e forense de SRE.
- Seguro por padrão — imagens distroless non-root, filesystem somente leitura, builds AOT e manifestos Kubernetes / OpenShift.
- Engenharia assistida por IA — desenvolvimento de software e fluxos multiagentes com o Claude, da Anthropic, e engenharia de prompts.
Todos os serviços usam Java 21, Micronaut 4, Project Reactor, arquitetura hexagonal, ADRs e imagens distroless non-root.
