About Sofiane

AWS certified DevOps, I can advise you on the architecture and services to use to create/migrate or consolidate your applications on the cloud.

I can develop your project alone or in collaboration. Front-end, back-end, or both.

My foundations:

• Client relationship: I am very available. I make sure to provide you with answers quickly, especially when you need them most, which is in case of bugs! Moreover, I always give you visibility on the progress of the development. Github, email, slack..., I adapt to your communication methods.

• Tests: I make sure to unit and integration test each component of the product I develop for you. No surprises upon deployment.

• Deployment: Deployment to production doesn't have to be complicated. Thanks to a panel of tools (Docker, CloudFormation, CodeDeploy, Git...), best practices (CICD, Mult-Stage...) and advanced deployment concepts (Canary, Immutable...), I can guarantee you that everything will go well.

• DevOps culture: I consider automation and sharing in a project as essential. Git, JIRA, Asana, Slack... These are part of the DevOps and Agile principles that I like to promote.

See you soon on Malt!
