Product Modernization
Existing software made maintainable again: refactoring, migrations, performance work, and a route out of technical debt without a risky rewrite.
When modernization is the right call
The signals are consistent: shipping a small feature takes weeks, nobody wants to touch one particular area of the code, the framework is several major versions behind, or a page that used to be fast now is not. The product works — it just costs too much to change.
A full rewrite is the most common answer to that and the most expensive way to get it wrong. Rewrites stall because the old system keeps needing features while the new one is not finished yet.
How we do it without stopping the product
We start with an assessment: what actually hurts, what it costs you now, and what the smallest change is that removes the pain. That produces a staged plan with independent steps, each one shippable on its own.
Then we work behind stable interfaces — a module at a time, a route at a time, a table at a time — so the product stays releasable throughout and any step can be paused or reversed without stranding you halfway.
Migrations get particular care: schema changes are run in reversible steps with a verified rollback, and data is validated before the old path is removed. We have done exactly this on our own product, moving Kevta from MongoDB to PostgreSQL behind an unchanged API surface.
What you get at the end
A codebase where the next feature is cheaper than the last one: current dependencies, tests around the parts that matter, a documented architecture, and the performance and observability work that makes problems visible before your users report them.

FAQs
Should we modernize or rewrite?
Modernize, in most cases. A rewrite makes sense when the product’s requirements have fundamentally changed or the platform is genuinely end-of-life — not merely because the code is unpleasant. We will tell you honestly which situation you are in after the assessment.
Can you work on a codebase you did not write?
Yes — that is most of this work. We start by reading the code and running it, then hand you a written assessment of what we found before proposing changes.
Will the product keep shipping during the work?
Yes. Every step is designed to be shippable on its own, so releases continue and you are never holding a half-migrated system that cannot go out.
What if the original team is gone?
That is a common starting point. Missing knowledge is recovered from the code, the database and the running system, and we document it as we go so the gap does not reopen.
How do you price it?
The assessment is a small fixed scope. After that, each stage is scoped and priced separately, so you can stop after any stage with a working product rather than committing to the whole programme up front.
