At Ejara SAS, I designed and operated production infrastructure across AWS and GCP, and led the migration of the production platform from GCP to AWS. I also standardised and operated infrastructure across approximately 18 blockchain networks.

As an independent consultant with Versified Technology Ltd., I improved a Moodle platform serving approximately 100,000 learners across 23 countries; Locust testing validated an approximately elevenfold increase in supported concurrent load. At Omni Strategies Ltd., I reviewed AWS architecture and costs, reducing monthly cloud expenditure by 49%.
