My background allows me to work across the entire technology stack - from databases, servers and networks to cloud infrastructure, CI/CD, containers, monitoring and applications. I am comfortable taking ownership of production environments, troubleshooting critical incidents, working independently, and collaborating with development, QA, infrastructure and business teams.
I am particularly interested in remote opportunities such as Cloud Engineer, AWS Engineer, DevOps Engineer, Senior Systems Administrator, Database Administrator, Cloud DBA, Infrastructure Engineer, Platform Engineer, Solutions Engineer, Technical Operations Engineer, IT Manager, Engineering Manager, and related senior technical roles.
