Your Product. Our Backend.
Senior software engineers who design, build, and operate production
backend systems — with a named architect accountable from whiteboard
to production.
CoreBackend LLC is a remote-first backend engineering firm based in Sacramento, California, serving clients across the United States.
What We Do
- System integration — connecting services, APIs and data across systems that were never designed to talk to each other.
- Performance & scale — finding and removing the bottlenecks that cap throughput and latency.
- Legacy modernization — migrating aging systems without stopping the business.
- Cloud & cost engineering — cutting infrastructure spend while improving reliability.
- Reliability & operations — building systems that hold under load and stay observable in production.
Systems We’ve Shipped
How We Work
- Architecture Review — a written report on your system: bottlenecks, risks, and a recommended plan. Free, and yours either way.
- Design & Plan — fixed scope and milestone billing, agreed before any code is written.
- Build & Ship — the engineer who designs your system builds and operates it. No juniors, no mid-project handoff.

material we train our own engineers with, including
