🚀 Engenheiro Full Stack (16 anos)
💳 Construindo sistemas financeiros de alta escala
⚡ Focado em performance, escalabilidade & sistemas distribuídos
+ Processando milhões de transações diariamente
+ Forte foco em arquiteturas distribuídas
+ Mentalidade de engenharia orientada a performanceComecei a programar com Java na empresa da minha família em Campo Grande/MS e evoluí para construir sistemas de alta performance e missão crítica para um dos maiores bancos da América Latina.
Hoje, projeto arquiteturas escaláveis e orientadas a eventos que operam sob carga extrema e restrições rígidas de confiabilidade.

💳 Building high-scale financial systems
⚡ Focused on performance, scalability & distributed systems
+ Processing millions of transactions daily
+ Strong focus on distributed architectures
+ Performance-driven engineering mindsetI started programming with Java in a family business in Campo Grande/MS and evolved into building high-performance, mission-critical systems for one of the largest banks in Latin America.
Today, I design scalable, event-driven architectures that operate under extreme load and strict reliability constraints.
