First we audit it. Then we fix it.
A slow legacy frontend, a framework three majors behind, a codebase nobody wants to touch. We start with a fixed-scope audit — a written report on what's actually wrong and what to fix in what order — then migrate incrementally, while your roadmap keeps moving.
- a written audit that stands on its own
- migration without a roadmap freeze
- green Core Web Vitals, kept green in CI
What you get
Concrete, inspectable output — the list below is what the engagement actually ships, not aspiration.
Codebase & performance audit
A fixed-scope, written report: architecture, dependencies, Core Web Vitals, and what to fix in what order. It stands alone — useful even if we never touch your code.
Incremental migration plan
Strangler pattern: the legacy app keeps serving users while routes move over one by one. No rewrite cliff, no roadmap freeze.
Next.js / framework migration
Off aging SPAs, jQuery-era stacks, or a Next version nobody dares upgrade — onto a current codebase you can hire for.
Dependency & build-tooling upgrades
Deprecated packages, minute-long builds, majors nobody dares bump — cleared out, with the upgrade path documented.
Green Core Web Vitals — kept green
We make the numbers green, then add performance budgets in CI so a regression fails the build instead of reaching your users.
Monitoring, guardrails, and handover
Error tracking and vitals monitoring wired in, plus written docs on everything we changed and why — the knowledge lands with your team.

Asked on most intro calls
Can you audit without taking over?
Yes — that's the point of productizing it. The audit is a standalone, fixed-scope engagement ending in a written report. Plenty of teams take the report and do the work themselves; hiring us for the fixes is optional, not implied.
Do we have to stop shipping during migration?
No. We migrate strangler-pattern: the old app keeps serving users while routes move over one at a time. Your team keeps shipping features throughout — that's a design constraint of the plan, not a stretch goal.
What if the codebase isn't salvageable?
Then the audit says so, in writing, with the numbers behind it — and what a rebuild would take instead. You get an honest answer either way; we don't sell migrations that shouldn't happen.
How long does an audit take?
Typically one to two weeks from repo access to written report, depending on the size of the codebase. You get a concrete date — and a fixed price — before we start.
Got a frontend everyone's afraid of?
Start with the audit. You'll know exactly what's wrong and what fixing it takes — whoever ends up doing the fixing.
