About
Great Expectations Group is a small, senior-only team based in San Francisco, California. We work directly with founders and product leads. No project managers between you and the people writing the code.
If you have a time-sensitive build, a system that needs reliability work, or an integration that keeps breaking, we can get it under control quickly.
Operating style
- Small surface area
- Shipping-oriented
- Documented decisions
- Clean ownership handoff
