A specialized engineering firm built on a single conviction: code migration should be automated, not manual.
Caldorin was born from a simple observation: companies spend millions of engineering hours on code migrations that could be automated. We partnered with Codemod — the leading code transformation platform — and built a firm dedicated exclusively to solving this problem.
We do only one thing: code migration and maintenance. No web design, no product development, no staff augmentation. This singular focus means every engineer, every process, and every tool we build is optimized for one outcome — transforming codebases at scale with zero downtime.
We build AST-based codemods — deterministic, testable, reusable transformation scripts that modify code at the syntax tree level. Unlike find-and-replace or AI-generated patches, our codemods understand code structure, preserve behavior, and scale to millions of lines.
As an official Codemod Certified Partner, we have deep integration with the Codemod platform and direct collaboration with their engineering team. This gives us early access to new capabilities and ensures our clients get the most advanced transformation tooling available.
We'd rather take an extra day to build a deterministic codemod than ship a fast, fragile migration. Accuracy compounds.
If a transformation can be automated, it should be. Manual code changes don't scale and introduce risk.
Every migration gets documented, every codemod is testable, every change is reviewable. No black boxes.
We don't just transform your code — we leave behind reusable codemods that your team can run again on future migrations.
