PROFILE
Geyslan Gregório
Guilherme Gonçalves contributed to aquasecurity/tracee by delivering robust backend and DevOps improvements focused on reliability, maintainability, and security. Over five months, he modernized the build system, enhanced CI/CD pipelines, and implemented containerized performance testing workflows using Go, Bash, and Docker. His work included hardening process lifecycle management, aligning event models between protocol buffers and core logic, and upgrading dependencies to address security vulnerabilities. By introducing health check enhancements and automating integration tests on host-based AMIs, Guilherme reduced test flakiness and improved operational clarity. His engineering demonstrated depth in system programming, dependency management, and scalable test automation for production environments.

Dec 1, 2025December 2025: Delivered a consolidated set of Tracee improvements spanning performance testing, process lifecycle robustness, event model consistency, dependency modernization, and CI stability. Key outcomes include enabling performance stress testing via a new EVT stress workflow, hardened process lifecycle with robust shutdown and zombie-process handling, alignment and cleanup of event definitions across proto and core, Go toolchain and dependencies upgrades for security and maintainability, and CI reliability improvements by centralizing PR formatting and temporarily disabling flaky proctree tests. Impact highlights: - Business value: provides a scalable, repeatable performance validation path; reduces risk of runtime leaks and zombie processes; improves maintainability and security posture; stabilizes CI for faster feedback loops. - Technical achievements: containerized stress testing architecture; daemonization and signal handling improvements; event ID/name normalization and proto-core alignment; dependency upgrades and tooling improvements; test-suite stabilization. Technologies/skills demonstrated: - Go toolchain upgrades (Go 1.24.11), dependency management (tracee/types) - Shell scripting and process control (setsid, zombie checks, graceful shutdown) - Containerization and privileged containers for performance tests - Proto/core event model alignment and maintainability - CI/PR tooling modernization and formatting automation
