Throughout my career, I have gained extensive experience in building resilient cloud architecture and delivering SLA and SLI with critical systems in production, often in the financial sector. My ability to run apps as a platform for internal developers has also provided them with added value and speed to their services.
I also manage to ensure the continuous uptime of critical systems in production 24/7, both in critical situations or writing runbooks and documentating important details about the system.
