João Gabriel Borba do Nascimento

Back-End Developer with 4 years in tech, 3 of them focused on software development.

I work daily with C#, .NET, Angular and SQL Server at Intermidia, where I took part in migrating a legacy Xamarin system to a modern Angular web platform.

In personal projects, I build with Java 17, Spring Boot 3, RabbitMQ and generative AI:

→ FortunAI — AI-powered personal finance app with a natural language chatbot, real-time investment portfolio tracking, Markowitz/Monte Carlo portfolio optimization, 464 automated tests and full CI/CD. Built as my thesis project and approved with distinction.

→ NotifyFlow — Async multi-channel notification engine (EMAIL, SMS, PUSH) with Outbox Pattern, Circuit Breaker, Retry and per-tenant Rate Limiter via Resilience4j. Deployed on Railway with GitHub Actions CI/CD.

BSc in Information Systems, Unisinos (2025).
Currently pursuing AWS Cloud Practitioner certification.
Targeting remote/international roles — open to relocation to Australia 🇦🇺
