Summary

Full-stack developer since 2022. I build complete web systems for companies: React interfaces, Node.js and Python APIs, PostgreSQL, ERP integrations, mobile apps and automations. Computer Science student.

Experience

• Build and maintain web systems for clients across industries with TypeScript, Node.js, React, Next.js, PHP and React Native.
• Business systems for HR, finance, billing, workshops, technical support, logistics and transport, from the database to the interface.
• A mobile app for barcode-based order picking and checking, with its rules covered by automated tests.
• Integrations with ERPs and partner APIs such as Omie, TecnoSpeed, Vuupt and D4Sign, plus PDF and Excel report automation.
• Python RPA robots and a platform to schedule and follow them on Windows workstations.

Case studies

• AuthSales, one foundation for several systems

  My personal project: a commercial SaaS platform that also serves as the foundation for systems in other domains, such as sales, healthcare and ERP.

• Picking and checking orders on the warehouse floor without losing track

  A phone app for pickers and collectors to scan products, split orders into parts and resume work where it stopped.

• The life of every device, from receiving to warranty

  A management system where every payment terminal is tracked by serial number through purchases, sales, repairs and warranty.

• Robots that drive systems with no API, and a panel to command them

  A platform to schedule and follow robots on Windows workstations across many clients, and robots that read tax documents without missing a cent.
