Marcelo Chies

Backend / Fullstack Developer

I build APIs, integrations, and digital products with a focus on clarity.

I am a Computer Science student who builds APIs with Python. I like understanding the problem, writing clear code, and following what happens in production.

Professional experience

Backend Engineering Intern

Autentique · Feb/2026 — Jul/2026

Worked on biometric and identity verification services with Python and FastAPI.

  • Facial recognition, liveness detection, OCR, and document classification.
  • GraphQL integrations and asynchronous processing with Google Cloud services.
  • Testing, log analysis, and production troubleshooting.

Personal projects

AgroRoute

Backend for drawing farm fields and calculating agricultural coverage routes.

APIs, integrations, and interfaces that work together.

My foundation is backend engineering: APIs, integrations, data, and cloud services. When a project calls for it, I also build the interface to deliver a complete solution.

I study Computer Science at URI and had my first professional experience at Autentique, working with Python, FastAPI, PHP, Laravel, GraphQL, asynchronous processing, and production troubleshooting.

Outside work and university, I practice competitive programming and build personal projects to explore new tools and different ways to solve problems.
