Freelancer profile translated to English.
Back to original languageAbout Julien
I offer my expertise primarily in Cloud and Big Data technologies.
With over 20 years of experience in digital development, including more than 10 years as an entrepreneur partner, my goal is to enhance your business value with your clients, investors, and users while optimizing your operating costs.
Self-taught, it is my passion that has allowed me to carry out numerous ambitious projects with their successes and failures.
The multiplicity of my experiences allows you to benefit from a versatile and agile profile for a rapid analysis of your needs and systems.
The main objectives of my recent roles consisted of migrating high-volume physical infrastructures to the Cloud. These experiences provide you with expertise in modern Big Data tools and virtualised infrastructures.
My international background and the diversity of my missions have given me a different perspective; I do not rely solely on the tools and methods I master, but propose the appropriate technologies, methodologies, and environments for each need.
Scope of my skills:
- System Administration (Linux, Cisco, Windows)
- Code Development (various projects in about twenty languages)
- Network and Telecommunications (10 years as a mobile operator)
- Cloud and Virtualization (3 high-volume system migrations)
- Methodologies and Agile Approach (Scrum, Kanban, KISS)
- AdTech (5 years in technology development, 10 years in media buying)
- Management (project management and team management)
- ITIL Processes and Awareness (MRC Accreditation)
- Web Development (around a hundred sites developed)
Despite over 10 years of managing teams and projects, I prioritize technical execution over project ownership, remaining directly involved in the architecture, design, integration, and maintenance of solutions.
