I build products end to end: from UI decisions down to cloud infrastructure. Comfortable shipping across language ecosystems and treating infra as a first-class part of the product.

Every project I build is provisioned with Terraform on AWS (Lambda, ECS, RDS, S3, CloudFront, Cognito, SQS, SES) across isolated dev/staging/prod environments with automated GitHub Actions deploys. I also have production experience with GCP and Azure.

People & resource management systems Multiple full-stack applications for workforce allocation and scheduling. Replaced manual infrastructure with IaC and CI/CD from scratch. Java React AWS GitHub Actions MariaDB

Service order management platform Full-stack platform for creating and managing service orders across web and mobile. Spring Boot API on ECS Fargate with Postgres/Flyway, React web app (Vite, Ant Design), and an offline-first Expo/React Native app — all consuming type-safe clients generated from the OpenAPI spec. Shared Terraform infrastructure includes a self-hosted Keycloak on ECS and a serverless Python job that powers down idle AWS resources outside working hours in non-prod environments.

M.Sc. in Mathematics — Universidade Federal de Uberlândia (2014). Former competitive speedcuber (1 South American record, 1 South American title, 2 South American podiums, 4 National Titles, 8 National podiums).

Musician, former math teacher (10 years). I also create content about programming, math, music, and speedcubing.

• Type-safe API contracts — frontend clients generated from OpenAPI specs so backend changes surface as compile errors
• Pluggable auth — Keycloak or Cognito depending on the project's needs
• Infrastructure reproducible from day one, not clicked together in a console
• AI-assisted workflows in regulated environments — established adoption standards at scale
