Foodhub
Senior Cloud and DevOps Architect · April 2020 to December 2021
Joined during COVID demand surge when ordering volumes spiked and platform reliability was under pressure. Scaled the food ordering platform to handle over 200,000 orders per day. Removed a testing bottleneck blocking 120 developers by designing Kubernetes-based per-pull-request environments with full-stack ephemeral test stacks.
