Fintech Loan API

A loan platform for a Brazilian agribusiness fund: APIs, a Flutter app for applicants, and crawlers ingesting public government data.

Private project

Source code is private — happy to walk a recruiter or hiring panel through it on a call.

What I did

Backend architecture in microservices, Flutter app for borrowers, ETL of public data (SIGEF, RFB) into MongoDB, code review and mentoring of a junior developer.

Key features

  • Microservices designed for fintech-grade scalability and security
  • Flutter app for loan applications and customer onboarding
  • Crawlers and ETL pipelines that normalize public government data
  • Public-facing portal built with Ghost CMS and Handlebars

A loan platform for a Brazilian agribusiness fund. We built the backend that powers the application flow, the Flutter app the borrower uses, and the data pipelines that pull and normalize information from a handful of public government APIs.
