Alec Holmes


I'm a software engineer with a wide-ranging background. Currently at Chronosphere, I'm building customer-facing alerting infrastructure, working on both the product and backend to support the observability needs of other sophisticated tech enterprises.

Prior to my current role, I worked as a senior staff engineer at Square's Cash App to help ship a Kubernetes-based platform running in AWS for product engineers at Cash App, including deploying a service mesh using Istio, scaling an internal pub/sub system using Kafka, and helping managing compute resources.

In the earlier days of Square, I was tech lead for the accounting and settlements systems as well as the reboot of the company's public developer platform.

Side projects

Cycling Weather

For cyclists in the microclimate-rich Bay Area, outings can traverse a variety of weather during even short trips. An information-dense weather mini-app helps plan at a glance, in a mobile-friendly format.


CSVQL helps with lightweight data analysis of CSV. Users paste in their CSV data and can run SQL queries over it. Querying is supported with SQLite cross-compiled to Javascript, so data is not transmitted to any server.
