About Jonathan

Linux system administrator specializing in the management of servers hosting websites and e-commerce stores. I can intervene to resolve a specific issue (slowdowns, errors...), perform diagnostics, conduct audits, carry out new installations, or offer long-term support in managing your servers.

Regardless of the technology used by your sites or applications (PHP/MySQL, WordPress, WooCommerce, PrestaShop, Symfony, Laravel, Python, Django, Flask, CakePHP...), I can provide you with turnkey solutions to ensure they are always responsive and your hosting is up-to-date, secure, and backed up. You remain the owner of your servers and domain names.

My scope of activity is not limited to web hosting; I am accustomed to working with the following technologies:
- Databases: MariaDB, MySQL, PostgreSQL
- NoSQL: Redis, Memcached, Elasticsearch
- Web servers: Nginx, Apache, Caddy
- Virtualization and containerization: KVM, Xen, Chroots, systemd-nspawn / systemd-machined
- Infrastructure as code: Salt (SaltStack), OctoDNS, Terraform
- Emails, contacts, and calendars: Postfix (SMTP), Dovecot (POP, IMAP, LMTP, Sieve), CalDAV, CardDAV, SPF, DKIM, DMARC
- Network: PowerDNS, BIND, OpenVPN
- Scripting: Bash, Python

Do not hesitate to contact me to discuss your projects!
