Junior DevOps Engineer, Infrastructure. Braga. Feb 2025 - Present

Infrastructure team member on an AWS stack with Cloudflare-fronted reverse proxy and traffic routing, and Datadog covering log, metric, APM, and DBM ingestion.
Onboarded untracked infrastructure into Terraform and extended Ansible playbooks for the Datadog Agent, Fluent Bit, SSH/SFTP, systemd-managed services, and log rotation, improving fleet management.
Migrated Java projects to Maven and CodeArtifact with CD scripts for the existing JBoss 7 app servers, giving teams a trackable CI/CD pipeline that improved delivery quality.
Planned and executed production cutovers for a MySQL to PostgreSQL migration, and rolled out Datadog APM and DBM for improved service and database visibility.
Tuned JVM settings with G1GC and asynchronous JBoss 7 state transfer, improving restart times and reducing OOM incidents.
On-call for the Infrastructure squad, contributing monitors, alerts, and SOPs, and driving incident response and postmortems.

System Developer Analyst, Backend. Braga. Mar 2023 - Feb 2025

Main maintainer of an internal fork of a 10+ year old JBoss-based tolling project (image review and toll processing), migrating the platform from JDK 8 to JDK 21 for better performance and security.
DevOps squad member, streamlining Maven/Docker artifact repositories, CI/CD pipelines, in-house Azure development, and Terraform-provisioned sandbox environments.
Restructured the build into a multi-module Maven project with a shared BOM and improved dependency caching, enabling multi-threaded builds nearly 6x faster and cutting build times by over 80%.
Contributed to the system design of a pay-per-mile tolling PoC, building CI/CD pipelines on GCP with Cloud Build, Cloud Run, and Cloud SQL, using Flyway for schema migrations and Pub/Sub for background processing.
Supported the GCP DevOps onboarding team, giving managers feedback for new joiners’ project placements.

Research Grant, HASLab. Braga. Jan 2022 - Jun 2022

Provisioned a 4-node Slurm cluster with Ansible, enabling repeatable setup for previewing HPC environments.
Piped performance and power metrics from RAPL into Prometheus and Grafana via a Docker Compose stack, making compute-vs-energy trade-offs visible for analysis.
Explored CPU frequency scaling configurations that reduced energy use and CO2 emissions with limited performance impact, informing the design of a green scheduler.
