Julien De Freitas

Freelance Cloud architect | Tech lead [DevOps, SecOps, FinOps]


As a technology enthusiast with a diverse background in subjects such as electronics, networking, telecommunications, project management, coding, and business, I have worked my way up from an IT Technician to a highly skilled Technology Consultant. With over a decade of experience in various roles including cloud architect, team leader, recruiter, CTO, and entrepreneur, I have gained the ability to excel in a variety of technical and customer-facing responsibilities. My strong technical knowledge, high-level architecture skills, and ability to craft a vision make me well-equipped to lead teams and engage with c-level stakeholders to bridge the gap between business and technical implementation. I am dedicated to delivering successful projects that meet the needs of startups and large enterprises alike.

Work Experience

Cloud Specialist

Faireach | April 2021 - Present

As a cloud expert with almost a decade of experience, I help customers achieve a successful transition to the cloud by addressing the following key areas: :

  • Strategy: I work with you to plan your cloud adoption or migration, taking into account your business drivers and assessing your current infrastructure. I can help you define new rules, processes, and teams, as well as the skills needed for a smooth transition.
  • Architecture : I can design a cloud infrastructure that meets your specific business requirements, including a landing zone and cloud-ready architecture for existing and new applications. I can also conduct a gap analysis of your current cloud infrastructure against best practices.
  • Security : I can help you secure your environment by defining or auditing your infrastructure against security frameworks such as CIS and CSA, and implementing the necessary tools, policies, and processes.
  • FinOps : I can optimize your cloud usage by analyzing your consumption to identify billing optimization opportunities, setting up compliance checks and tools, and providing dashboards and alerting.
