Software Developer • Backend Engineering • High-Availability Systems

• I’m a Software Developer at Claro (iMusica), working on backend services and platform integrations.
• Previously, I worked at Nelogica, developing high-performance systems used by over 300,000 traders.
• I hold a B.Sc. in Computer Science from UFRRJ (cum laude).
• I have strong experience building high-availability backend systems, focusing on WebSockets, raw TCP, proxies/gateways, metrics, and event-driven architectures.
• Passionate about clean architecture, concurrency, observability, and designing reliable systems.

Languages: Java, Go, PHP, Delphi, Python, C, C++
Backend & Architecture: REST APIs, WebSockets, TCP servers, service-oriented design
Concurrency: thread pools, futures/promises, queues, async processing

Messaging & Async Systems: Kafka, RabbitMQ, event-driven architectures, distributed queues
Observability: Micrometer, Prometheus, Grafana, structured logging
Infrastructure & Tools: Docker, GitHub/GitLab, CI/CD, AWS, PostgreSQL, MongoDB

Some of the projects I maintain or contribute to:

• Curupira — Annotation-based Java framework for Discord bots, inspired by Spring Boot.
• Capivara — Discord bot with dynamic voice channels, role automation, embed correction, and metrics.
• Cuca — Domain-based email authentication bot using SMTP + token generation.
• ADDAOU-PAPI — Sorting algorithm performance analysis using PAPI (C/C++/Python).

• Reliability first: systems must be predictable, observable, and fail gracefully.
• Elegant simplicity: APIs and abstractions should be powerful and easy to understand.
• Maintainability: clean design, modular code, and thoughtful testing.
• Community-driven: I believe in contributing back to open-source whenever possible.
