About

It started with a computer my grandmother gave me when I was around 9. I played games on it, and soon I was changing them, building mods for Minecraft and Habbo. By 13 I was running my own game servers and writing Java plugins for Minecraft with Bukkit and Spigot. Servers have players, and players notice when something breaks, so I taught myself how real systems fit together. Mine had to keep working.

That curiosity never left, but at 18 I turned it into a job. In 2019 I joined an agency and got my first professional reps with PHP, MySQL, and the web fundamentals: HTML, CSS, and JavaScript.

Around the same time I worked mornings and studied Industrial Mathematics in the afternoon at the Federal University of Paraná. After a semester I knew engineering was where I wanted to be, so I switched into Computer Science and committed to it fully.

Since then I have worked across the stack and grown into platform and product engineering, including almost two years living in Frankfurt. I am comfortable from cloud infrastructure and backend systems up to the frontend and mobile apps people actually use. I am usually the one who sets up testing, observability, and CI standards, and I enjoy mentoring. Today I keep building, including the systems behind Uranus, the company I founded.

  • JavaScript/TypeScript, Golang, Python, PHP, Java
  • AWS, GCR, DigitalOcean, Kubernetes, Docker, Terraform/IaC
  • React, React Native, Next.js, Vite, SSG, design systems
  • Event-driven architecture, microservices, domain-driven design

Self-assessed, relative depth: strongest in backend, platform, and cloud. I work across the rest with solid knowledge, but I am not a specialist in everything.

  • Backend & distributed systems: JavaScript/TypeScript, Golang, Python, PHP, Java, Event-driven architecture, API & integration design, Microservices, Domain-driven design, Clean architecture, Hexagonal architecture
  • Platform engineering & cloud/infra: AWS, GCR, DigitalOcean, Kubernetes, Docker, Terraform/IaC, Linux, CI/CD, reliability, developer tooling (CLI tools, documentation)
  • Frontend & mobile: React, React Native, Next.js, Vite, SSG, TypeScript, design systems
  • Observability & quality: Grafana, Prometheus, Datadog, Elastic / LGTM stack, Testing & load (Jest, k6)
  • Data: PostgreSQL, MySQL, MongoDB, Redis
  • AI engineering and development: Spec-driven development, Agentic workflows with LangChain and LangGraph (Python and TypeScript), Text, image, and audio models (OpenAI, Anthropic, ElevenLabs, Gemini), Skills, tools, and memory augmentation (RAG), Vector databases (Qdrant, pgvector, Redis), Knowledge graphs (Neo4j, ArangoDB), Semantic search and embeddings (OpenAI, Gemini)

  1. Senior Software Engineer · Thinksurance

    Jan 2023 – Present · 3 yrs 6 mos

    Frankfurt & Curitiba (now remote) · Germany's largest commercial insurance platform.

    1. Jan 2023 – May 2024Remote from Brazil1 yr 5 mos
    2. Jun 2024 – Apr 2026On-site in Frankfurt am Main, Germany1 yr 11 mos
    3. May 2026 – PresentRemote from Curitiba, Brazil2 mos

    I relocated to Frankfurt am Main, the financial center of Germany, in mid-2024 on an EU Blue Card and worked on-site for almost two years. Since the end of April 2026 I have been back in Curitiba, still at Thinksurance, working remotely.

    • Architected a new insurer-integration model from the ground up. It became the platform's core integration process and drove 300% growth in active integrations and a 5x jump in SME revenue.
    • Helped rebuild the entire proposals and contracts experience for commercial insurance.
    • Remodeled core microservices with observability, testing, and reliability improvements, and automated the integration lifecycle on AWS and CI/CD. A legacy system was retired and operating headcount dropped from 10 to 2 engineers without losing reliability.
    • Built inner-source packages for code reuse across services, including internal packages for n8n automations.
    • Set standards for AI-assisted automation, AI code review, and spec-driven development of new features.
    • Remodeled and optimized databases to follow normal forms, and mentored engineers while setting backend-chapter standards for tooling and monitoring.
    • TypeScript (NestJS, TypeORM)
    • Golang
    • PHP (Symfony)
    • AWS (EKS, EC2, RDS, S3, SQS, SNS)
    • Kubernetes
    • Docker
    • MySQL
    • Redis
    • MongoDB
    • Terraform

  2. Software Engineer · Olist

    Apr 2021 – Dec 2022 · 1 yr 9 mos

    Curitiba, Brazil · Brazil's leading SME e-commerce + Banking-as-a-Service platform.

    • Architected an automatic invoicing system (Nota Fiscal) for SMEs in real time, with a hexagonal microservice architecture (Node.js, TypeScript) and clear domain boundaries, connecting the existing system to this new billing engine.
    • Migrated a company acquisition's architecture from a monolith to microservices for marketplace channels.
    • In that new model, built an event-driven communication layer (Kafka, AWS SNS/SQS).
    • Integrated Infrastructure-as-Code (AWS) together with the application code.
    • TypeScript
    • Golang
    • Python (Django)
    • AWS (Lambda, ECS, EC2, RDS, DynamoDB, S3, SQS, SNS)
    • Kafka
    • Redis
    • PostgreSQL

  3. Software Engineer · CINQ (now CI&T)

    Mar 2020 – Mar 2021 · 1 yr 1 mo

    Curitiba, Brazil (remote, U.S. client) · Consulting for U.S. client RepairQ / Service Central (mobile device repair industry).

    • Designed a new integration model for the core repair flow, enabling direct partnerships with Apple, Google, and Samsung through global systems such as Apple GSX.
    • Streamlined OEM integrations so authorized partners synced automatically with manufacturer systems.
    • Implemented Docker and CI/CD pipelines.
    • PHP (Laravel)
    • MySQL
