I make PHP and Laravel applications faster and cheaper to run.

At my current job

• Since 2016I run the infrastructure of one platform: about 20 AWS instances and more than 100,000 users. I moved it from dedicated servers to AWS, fully managed with Infrastructure as Code.
• 99.992% uptimeFor the website over the last 12 months, with 7 of the 12 months at 100%. Measured by Oh Dear.
• 20% cheaper app serversI moved the whole fleet to ARM (AWS Graviton). On the application servers, the instances cost about 20% less.
• 3.5 TB → 800 GBAbout $270 a month less for backup storage, and the backups now survive the loss of the AWS account.

Outside my job
