About

I’ve been coding since I was 14, starting with Minecraft mods in Java, which eventually led me down the rabbit hole of low-level programming with C and tinkering with simple NCurses apps.

Studying computer engineering at UTFPR deepened my love for programming, and now I’m comfortable with C, C++, Python, Go, Java, and JavaScript, along with tools like LaTeX, PostgreSQL, Redis, OpenCV, NumPy, and Docker.

Experience

Throughout my journey in software development and research, I’ve had the opportunity to work on diverse projects, from academic research to professional SaaS development. Below is a timeline of my professional and research experiences, highlighting contributions in distributed systems, applied cryptography, and backend engineering.

  • Scientific Research Scholarship - RNP
    November 2024 - November 2025 | Toledo, Brazil

    Integrated post-quantum cryptography into blockchain, analyzing efficiency and optimizing signature sizes for long-term security. Implemented Go bindings and adapted the Go runtime for Hyperledger Fabric integration.

  • Scientific Research Scholarship - PIBITI
    September 2024 - November 2024 | Toledo, Brazil

    Researched post-quantum cryptography applied to lattice-based systems, studying KEMTLS and post-quantum TLS protocols, and implementing cryptographic primitives focusing on security and efficiency.

  • Junior Software Developer - NeticShard
    April 2024 - March 2025 | Remote, LATAM

    Developed backend for a SaaS IT incident response platform in Go. Implemented unit, integration, and E2E tests, structured CI/CD pipelines, applied Domain-Driven Design principles, and built modular architecture.

  • Undergraduate Research Assistant - UTFPR
    2023 - 2024 | Toledo, Brazil

    Researched lattice-based post-quantum cryptography, implemented the Goldreich–Goldwasser–Halevi (GGH) cryptosystem, and performed experimental analysis of computational properties.
