Solutions Architect @ Zappts

Rafael Porto Vieira de Moura

I take AI systems from pilot to production — reference architecture, GCP and Kubernetes, with governance and end-to-end traceability.

Divinópolis, Minas Gerais, Brazil

About

I started as an intern in September 2021, writing Lambda functions and deployment pipelines on AWS. By September 2025 I was leading end-to-end architecture for an enterprise AI platform. The path between those two points ran through junior, mid-level, and a stretch where I was the only backend developer on an entire project.

That stretch is where it clicked. Being solely responsible for a production system teaches you fast that the expensive decisions are not about code — they are about boundaries: what each service knows, who is allowed to call whom, and how a change reaches production without anyone holding their breath.

That is the work now. I design distributed systems other people can operate: reference architecture written down as ADRs, microservices on Kubernetes with event-driven messaging, and a GitOps pipeline where every change is traceable from commit to cluster. I hold a Computer Science degree from UFLA, with a thesis on microservices architecture, and I am pursuing an MBA in Software Engineering at USP/Esalq.

    AI platform for institutional investing

    End-to-end architecture for a system that turns unstructured investment knowledge into auditable analysis. I took the platform from pilot to a multi-asset-class solution: microservices on GCP and Kubernetes, event-driven messaging, an LLM file-processing pipeline and a GitOps delivery chain traceable from commit to cluster.

    Microservices Architecture

    A complete e-commerce system decomposed into six independent services — authentication, orders, products, stock and contact integration — each with its own repository, pipeline and lifecycle. Written in TypeScript with Fastify and Zod, on AWS Cognito, SNS, SQS and KMS, with versioned infrastructure and a Jenkins pipeline.

    Strategic client backend

    As the only backend developer on the project, I designed and implemented the entire solution — from defining the architecture to the day-to-day technical calls. Cloud services focused on scalability, reliability and production support, sustaining continuous delivery throughout the contract lifecycle.
