Jonathan Collett

A technical engineer experienced in application support, deployments, and environment management across cloud-based systems, working with web applications and microservices in staging and production environments. Skilled in troubleshooting and automation using PowerShell, SQL, and Azure-based tooling. I leverage PowerShell and SQL, sometimes using AI-assisted scripting, along with Azure-hosted infrastructure, Datadog, Azure DevOps, and Git, to troubleshoot issues, streamline workflows, and support CI/CD processes.

I enjoy solving problems methodically, collaborating with teams, and staying calm under pressure. Outside work, I pursue technical hobbies like building custom PCs and keyboards, reflecting my curiosity and problem-solving mindset.
