Why Hire Us for Legacy Modernization

Incremental Migration

We modernize piece by piece using the strangler fig pattern. No big-bang rewrites — your app keeps running while we upgrade it.

Risk Assessment First

Every project starts with a thorough codebase assessment. We identify risks, create a prioritized roadmap, and estimate costs before any code changes.

Performance Gains

Database optimization, caching, background jobs — we typically achieve 5-10x performance improvements.

Security Focus

Outdated dependencies are a security risk. We patch vulnerabilities, upgrade gems, and implement modern security practices.

Frequently Asked Questions

How long does a Rails upgrade take?

A minor version upgrade (e.g., 6.1 to 7.0) typically takes 2-4 weeks. Major upgrades spanning multiple versions (e.g., 4.2 to 7.1) can take 2-3 months depending on the app's complexity and test coverage.

Can you modernize without rewriting everything?

Yes, that's our approach. We use the strangler fig pattern — replacing old components incrementally while the app continues to run in production.

Do you add tests to legacy apps?

Yes. We add test coverage as part of the modernization process, focusing on critical business logic first. This makes future changes safer and faster.
