Antifraud in a banking environment
A .NET and RabbitMQ module to analyze transactions in a critical flow and contribute to the identification of more than 200,000 fraudulent transactions.
Backend, microservices and distributed systems with practical depth.
I build and maintain software in domains where reliability, architecture clarity and response time matter: core banking, antifraud, KYC, integrations and applied AI.
About
I am a Software Developer and Computer Science undergraduate at the Federal University of Sergipe. My work combines backend, fullstack, architecture and systems integration, with a special focus on critical products and distributed systems.
I like building software that stands up in the real world: systems shaped by solid architecture decisions, clear code, tests, observability, maintainability and measurable impact.
Enough architecture for the problem, not for display.
Messaging, caching and data storage treated as product decisions.
Interfaces and APIs designed for maintenance after deployment.
Selected case studies

A KYC analysis flow with NestJS, MongoDB, RabbitMQ and Redis, automating customer onboarding from 2 days to up to 4 hours.
A RAG pipeline with VitePress, chunking, PGVector, embeddings and Llama 3.2 to answer user questions.
