At Hallopay, I led the deployment of cloud-based solutions that increased system efficiency by 30%, and spearheaded a legacy-system upgrade that improved processing speed by 60%. I also implemented automated testing protocols that reduced bugs before product releases.

I built a distributed data ingestion and analysis system for football betting data, with RabbitMQ message queues, background workers, and a React frontend. I also maintain Shoptric Ecommerce and assist with dashboards for SMS-based services at Ampletech DeveloperSupport.
