My role at ezyVet is primarily focused on improving performance and response time across the full stack from PHP, MySQL and ElasticSearch improvements to optimizing AWS usage and cost.

- Pushing for latest versions of services to keep frameworks up to date and utilize any performance improvements (PHP, MySQL, Elasticsearch, Redis upgrades)
- Building automation pipelines through GitLab CI
- Experience building a cross-platform Go application utilizing Websockets with AWS API Gateway and SQS/SNS/DynamoDB/Lambda/Terraform
- Creating a full docker development environment for engineers to improve development workflows
- Reducing RDS load and improving SQL query response time via query restructuring to make better use of compound indexes and foreign keys
- Rebuilding Elasticsearch clusters to improve redundancy and response time with optimised indexes
- Writing custom service monitoring tools in Go that interface directly with Docker, ElasticSearch and PHP-FPM
- Optimising MySQL parameter groups to get the most out of each instance
