Technical responsibility

FreeBSD

Operating system and foundation of the production platform.

Go

Language used for the rebuild from 2014 to 2019.

End to end

Engineering and operation across system and application boundaries. Responsibility for rebuilding the application and running it in production, not just for an individual component.

Period and role

Lead/Sole Engineer from 2014 to 2019. The role, dates and responsibilities are first-person statements; this page is not independent confirmation by the current operator.

Boundary: no Kubernetes

The platform described here used Go on FreeBSD. Kubernetes belongs to other platform and cloud projects, not this rebuild. No publicly verified user, traffic or revenue figures are claimed here.

From this work to your project

Production experience for your platform

Application development and operations still belong together: traceable deployments, clear ownership and recovery plans. Existing platform teams can engage for architecture and implementation work; recurring incidents call for a focused SRE review.
