Your Product. Our Backend.
Founder-led backend engineering: we design, build and support
production systems, and the engineer you talk to leads and builds the work.
CoreBackend LLC is a Los Angeles-based backend engineering firm, working remote-first. Founder-led; senior engineers engaged per workstream.
What We Do
- Integration — your systems connected through their APIs, including Salesforce, Dynamics, SharePoint or Esri/GIS, and reporting databases filled automatically from them (we build the data and backend behind your dashboards); every transfer reconciled, retries de-duplicated.
- Data migration — profiling, scripted conversion, two rehearsal runs, record-by-record reconciliation.
- Legacy modernization — old interfaces and nightly jobs documented with tested recovery runbooks; a secure, documented API in front of an older system.
- Reliability & performance — backups proven to restore, alerts that matter, outage causes fixed; slow screens, reports or processes measured and fixed.
- Cloud infrastructure — AWS or Azure environments set up, automated and kept affordable: infrastructure as code (Terraform), deployments, monitoring, and a line-by-line cost review with safe savings changes.
- Support retainer — a fixed monthly fee for alerts watched, fixes and small changes after go-live; acknowledged the same business day, engineering response the next.
- Custom application development (quoted per project) — larger builds such as case management, licensing or permitting: server, database, workflow rules and reports, in two-week increments.
- Also available on request: single sign-on, AI document search, and compliance-ready backends (audit logs, encryption, role-based access and retention; evidence for your review; we do not certify).
- Backend first. When a project needs front-end or design work, we work alongside your team or bring in a trusted specialist.
