Gerardo Puerta
Senior systems, SRE and platform engineer
I build and operate reliable systems across Linux, cloud infrastructure, Kubernetes, embedded devices and distributed platforms. My work lives where production reliability, debugging, automation and real-world operational pressure meet.
Over the last two decades I have worked on fleet-scale Linux environments, cloud-native backends, infrastructure automation, edge-to-cloud platforms and operationally messy systems that had to keep working.
What I work on
- Linux systems engineering and production troubleshooting
- Site reliability, incident response and observability
- Kubernetes, cloud platforms and infrastructure automation
- Embedded Linux, edge systems and awkward real-world integrations
- Platform thinking that reduces toil and helps teams move faster
Selected projects
- Platform, reliability and operational tooling Cloud-native infrastructure, deployment workflows, diagnosis and supportability tooling.
- Embedded Linux and Bluetooth device platforms BLE scanning, service integration, OTA-adjacent work and device-side Linux engineering.
- Backend systems, APIs and product infrastructure Service glue, internal tools, chart generation, messaging and end-to-end systems ownership.
Selected writing
- opkg, multi-cluster thinking and Istio Recent infrastructure/platform writing
- T430 EC and stock BIOS notes Hardware, firmware and practical low-level debugging
- Tuning MariaDB on Raspberry Pi for Pi-hole Small systems, performance tradeoffs and pragmatic operations
- Netatalk with Winbind auth Real integration work across Linux, auth and operational edge cases
