Build · Google Web Toolkit Development

The system too critical to switch off.

A legacy GWT app still settles real money. Migrating it the wrong way breaks both.


Overview

Many institutions still run critical applications on Google Web Toolkit. We maintain those systems for the organisations that depend on them and plan migrations for teams ready to move on. We know what business continuity means in finance: transitions designed to lower risk, not to satisfy a roadmap.

What it includes

The work, named plainly.

01

Kept running, not abandoned

We maintain and extend existing GWT applications, fixing, adding and keeping them reliable. We know GWT internals and the Java it sits on.

02

A plan, not a rewrite

We assess the codebase and set an incremental path to React or SvelteKit. Continuity first: there is no big-bang rewrite.

03

Replaced piece by piece

The strangler-fig pattern: modern components take over one at a time while the existing system keeps serving users. No downtime.

How we work

Engineered once. Maintained indefinitely.

  1. 01 Audit the version, dependencies and technical debt
  2. 02 Weigh the migration options against business risk
  3. 03 Set an incremental roadmap with measurable milestones
  4. 04 Run legacy and modern components side by side
  5. 05 Hand knowledge to your team as you go

Migrate it without breaking it.

We reply within one working day, from an engineer, not a pipeline.
