DevOps & Platform Engineering

Hi, I'm Herbert

I'm a DevOps engineer focused on automation and observability who enjoys solving complex automation challenges. I focus on reducing operational overhead and eliminating monitoring blind spots by building reliable pipelines, infrastructure-as-code, and scalable container platforms to accelerate delivery and improve system resilience.

As Director of Infrastructure at Uaná, I lead the strategy and operation of the company's platform — designing reliable, automated and observable systems that scale with the product. My work centers on infrastructure-as-code, resilient container platforms and strong observability, cutting operational overhead so the engineering teams ship faster and with confidence.

It's my largest and most complex personal project, which I have maintained for five years. Currently it's a cluster running multiple services. My goal was to create a system that I can build, destroy, and rebuild from scratch to test infrastructure patterns, automation approaches, and high-availability architectures. I have learned many valuable lessons from this project.
Network device backup

Network device backups

Fully automated backup and versioning of network device configurations

This project involved creating a fully automated system for backing up and versioning a large inventory of network devices. The goal was to ensure that all configurations were regularly backed up and could be easily restored in case of failure or misconfiguration. The system also included versioning capabilities, allowing for easy rollback to previous configurations if needed.
