Hi! I'm a senior systems and infrastructure engineer with 18+ years of experience designing and operating complex Linux and network-based platforms in highly regulated, mission-critical, and hyperscale environments. I recently joined Red Hat as a Senior Consultant, where I help organizations design, deploy, and operate enterprise open source solutions at scale. In parallel, I'm pursuing an M.Sc. in Systems Engineering and Computer Science (PESC) at COPPE/UFRJ, focusing on Computer Architecture and Operating Systems. Previously, at Amazon Web Services (Ireland), I designed and built a custom, large-scale network discovery system under extreme constraints, providing the first visibility into a legacy Layer-2 console network that had become a structural bottleneck to AWS datacenter growth. The system mapped hundreds of thousands of heterogeneous network devices across AWS datacenters, enabling the migration to scalable Layer-3 architectures. I also contributed to hardware enablement by working on a Linux Buildroot–based embedded operating system and developing user-space CLI tooling for custom terminal-server hardware. My current focus is deepening expertise in computer architecture, operating systems, and low-level software. I'm open to academic collaboration, research discussions, and technically challenging conversations around Linux internals, RISC-V, and systems design. My journey with computers began in childhood with a 286 IBM PC, where I built menu-driven interfaces so my father could launch his programs without typing commands in DOS — an early sign of my curiosity for how things work under the hood, which later led me to Slackware and Gentoo Linux in the early 2000s. Obsessed with squeezing the best performance from my old machines, I ran Gentoo for a while just to compile everything from scratch with CPU-specific optimization flags. During that time, I also contributed to open source as a maintainer of some Slackware Linux Slackpkg packages, writing the build scripts used to generate installation packages.

• Joined the newly formed private company as the first technology hire, establishing the technology function from zero and initially owning hands-on infrastructure and systems operations while recruiting and structuring the team. • Delivered a centralized data lake and warehouse supporting multiple analytics, including geospatial insights that enabled marketing to decide the location of a new physical store within minutes and enabled CRM implementation. • Delivered a same-day custom GUI application integrating retail point-of-sale with the club’s fan membership platform, unblocking the on-time launch of the first physical store and enabling correct discount application by membership tier. • Redesigned the match-day video analysis workflow by implementing a low-latency RTSP streaming pipeline using GStreamer, reducing end-to-end delay from 10s to 5s while improving analyst productivity and preserving privacy. • Owned technical coordination for a multi-vendor fan mobile platform, integrating ticketing, membership, and e-commerce systems to deliver in-app ticket purchases, loyalty features, and AR experiences, and piloted facial-recognition stadium access before halting deployment due to hardware constraints incompatible with production conditions. • Led the technical due diligence of a stadium-scale Wi-Fi program targeting simultaneous connectivity for 30,000 fans, benchmarking international venues, evaluating vendors and hardware ecosystems, and co-designing AP placement to support high-density social media traffic; project was fully specified before being paused due to board-level reprioritization.
• Designed, built, and operated a bespoke network discovery system for all AWS datacenters, delivering the first visibility into a console-only (RS-232), legacy Layer-2 network that had become a scalability bottleneck for datacenter growth. Engineered a production-only, multithreaded discovery platform — without SNMP or SSH — capable of identifying hundreds of thousands of heterogeneous devices by dynamically parsing vendor-specific console outputs and leveraging multiple neighbor-discovery protocols (e.g., CDP, LLDP, ISDP), enabling accurate topology mapping and unblocking migration to scalable Layer-3 architectures. • Developed automation tools in Python to rotate credentials and orchestrate network-migration tasks, reducing manual errors and cutting region-wide credential rotation from days to hours, and individual DC fabric migrations from 5 to 2 days. • Participated in building a Linux Buildroot-based operating system for a new terminal-server hardware, and developed its CLI.
• Designed and delivered the organization’s first Internet-facing application platform, deploying hardened JBoss and Apache servers on RHEL with Ansible and CIS benchmarks, enforcing mutual authentication and end-to-end encryption across all tiers, and integrating F5 Web Application Firewall to meet Central Bank–level security requirements. • Reduced site role-exchange time during disaster recovery exercises from 4 hours to 16 minutes by defining and implementing the DR automation strategy. Authored standardized shell scripting guidelines and reusable function libraries, automated DNS (BIND) role switching, and orchestrated end-to-end execution through Jenkins Pipelines.
• Significantly reduced application downtime by redesigning the architecture of 40 JBoss EAP instances, eliminating cascading failures where a single application outage previously impacted an average of 10 additional instances. • Introduced GitLab for infrastructure teams and led Git/GitLab onboarding and training, while supporting development teams with JBoss EAP 6 and CI/CD pipelines using Jenkins, Sonar, and Selenium.
