What I do
2023 to presentI lead engineering and operations for a multi-tenant compliance platform. The product is PHP and Laravel. The services and tooling around it are Go.
Most of the work is performance and reliability under load. A missing index was making every API write scan a full audit table, pulling far more data through the buffer pool than it could hold. Adding it took client API writes from 300 seconds, where they were hitting the web server timeout, to consistently sub-second.
I also run the estate it sits on: VMware ESXi hosts and Linux virtual machines, patched, backed up and restored. The monitoring and alerting stack was built in-house from nothing, with the database exporter scoped so it cannot read customer data.
