Products and studies, from back-end to interface.

About

I am a full stack developer focused on financial products and Web3. I work across the TypeScript ecosystem, with Node.js, NestJS, React and Expo, from the back-end and database to mobile apps.

I started in mechanical engineering, which gave me a strong foundation for analyzing and solving complex problems. Today I work exclusively in software, a field I specialized in through FIAP's Pós Tech program.

My focus is understanding the business rules in depth, especially in the crypto asset market, and turning them into clean code, stable systems and applications that are safe for the people who use them.

Services

Four ways to work together.

  • 01 / 04

    Full web application

    From database to screen. You describe the business, I deliver the product running.

    • React front-end with Next.js
    • Node.js and NestJS back-end
    • PostgreSQL modeling with Prisma
  • 02 / 04

    Mobile application

    One codebase, Android and iOS. React Native with Expo, shipped to both stores.

    • React Native with Expo
    • Integration with your product API
    • Push notifications and offline state
  • 03 / 04

    Custom API and back-end

    When the server is the bottleneck: APIs that hold load, queues that do not drop work, and data that does not corrupt.

    • REST APIs in NestJS and TypeScript
    • Async processing with BullMQ and Redis
    • Real-time over WebSockets
  • 04 / 04

    Integrations and payments

    The part nobody wants to do: connecting your system to external providers without double-charging or losing events.

    • Webhooks with HMAC validation and idempotency
    • Payment gateways and card issuers
    • Multi-blockchain crypto integration (EVM, Solana, Tron)
