Systems that scale. Code that doesn’t break.
Pragmatic, predictable, and measurable engineering.

🧩 Engineering Principles

  • Predictability over improvisation: architecture is planning, not reaction.
  • Sustainable performance: optimization is not about speed — it’s about consistency.
  • Functional simplicity: fewer abstractions, more clarity.
  • Complexity cost: every if costs, every cache lies.
  • Real scalability: systems shouldn’t rely on luck, but on design.

🏢 Professional Experience

🔹 Serasa (via Verx) — Judicial Systems and Anti-Fraud AI Engineering

Senior consultant leading the architectural and technical evolution of the judicial order processing system, focused on performance, scalability, and operational intelligence.

Key contributions:

  • Complete redesign of the judicial annotation processing pipeline, integrating with a mainframe and automating large-scale file reading;

  • Full digitalization of physical archives, unifying multiple data sources and metadata standards.
  • Authenticated WebSocket implementation (no SockJS) for real-time communication between system modules.
  • Resource optimization and autoscaling: memory usage dropped from 2 GB to 300–400 MB; pods reduced from 12 to 2 while keeping heap under 1 GB.
  • Database tuning with dynamic indexing via Mongock, executed in background without blocking pod startup.
  • Direct upload integration via signed URLs, offloading the API layer.
  • AI proof-of-concept to interpret judicial orders, linking CPF and decisions while detecting potential fraud attempts.

Key contributions:

  • Detailed REST logging via Spring interceptors, tracing service-to-service calls for error, latency, and behavior tracking.
    • Greatly improved diagnostic capability and incident visibility.
  • Enhanced monitoring and reliability of distributed services:
    • Log audits, incident analysis, and small-scale corrective improvements;
    • Dashboard and alert refinements for clearer operational insights.
  • Deployment execution via Jenkins and Terraform:
    • Ran and validated 70+ microservices;
    • Post-deployment checks ensuring REST communication integrity.

Stack: Java · Spring Boot · Jenkins · Terraform (execution) · Microservices · ELK Stack · Observability

Impact:
Expanded operational visibility and traceability in a distributed environment.
Targeted, high-precision contributions — practical and stable engineering under constraint.

🔹 Viasoft — Technical Leadership and Java Engineering Consolidation

Joined as a mid-level developer (Delphi) and advanced to technical and product lead.
Period of transition into Java engineering, taking ownership of architecture, team, and product direction.

Key contributions:

  • Full refactor of a REST system initially built on singletons, migrating to a scalable, stateless design.
  • Technical and product leadership: code review standards, delivery prioritization, and Scrum Master role.
  • Sales Platform (Java + Angular + Android) — primary product under my direct leadership:
    • Web admin module and Android field app;
    • Stability and performance improvements across the stack;
    • Continuous iteration based on reseller feedback.
  • Supported additional corporate systems: ERP, logistics router, marketplace hub, and reporting tools.
  • Team training and process standardization, ensuring stable builds and shared discipline.
