Summary

GNU/Linux system administrator.
More than 15 years of experience.

On previous assignments, I administered up to about sixty servers, hosting a variety of services (web servers, databases, monitoring and alerting systems, name servers, data stores, e-mail hosting infrastructure, load balancers, …). Sometimes under automated orchestration contexts, often using virtualized servers, always with high availability in mind.

I also held server-side development and integration roles on web applications; my last experiences mainly involved content management systems. I master the technical web science, from network layer to client layer.

I aim to pursue system administration work, in a diversified responsibilities context, on projects both stimulating and serious.
