Freelancer profile translated to English.
Back to original languageAbout Johan
Having been responsible for more than 15 years for critical IT infrastructures (hospital, bank, public service), I have acquired solid experience in multiple areas: databases (Oracle, MS SQL Server, MySQL, PostgreSQL), virtualization (VMWare), Operating Systems (Linux and Windows), storage (Dell/EMC, NetApp), backup (Dell/EMC, Veeam), monitoring (Nagios, Zabbix).
This diversity of experience has allowed me to hold project management and IT service management positions in large companies.
In parallel, I launched my own web development company (PHP Laravel) and launched a platform with over 25,000 users. I employ four developers who are now autonomous and work using the Scrum method, which I learned on that occasion.
I consider one of my greatest assets to be my ability to learn new technologies and adapt to very varied situations, and I therefore offer to put my experience at the service of your projects!
