Do I have to stop the application during modernization?

No. We modernize incrementally: the old system keeps running in parallel with the new one, with no big-bang and no visible downtime.

Do you rewrite from scratch or refactor what I already have?

It depends on the audit. We usually keep and refactor what's worth it and rewrite only what's necessary. If you want a brand-new system, from scratch, that's web development; if you only want to move your infrastructure to the cloud, that's cloud services.

How long does a modernization take?

It depends on the size and state of the system. After the audit you get a prioritized plan, with steps and an estimate, so we modernize what matters most first.

Do you keep the existing data and features?

Yes. The incremental migration runs old and new in parallel, with data validation, so you lose nothing along the way.

What do I do if nobody understands the old code anymore?

That's exactly why we start with a code and architecture audit: we document the system, assess the technical debt and clean up the legacy code, so your team can maintain it again.

App Modernization

Old code is slowing you down. We modernize it.

We bring legacy applications to a modern architecture without stopping your business: faster, easier to maintain and with no data loss.

Why it matters

The old system is holding you back. We bring it up to date, without taking it offline.

Legacy applications and systems modernized to modern architectures, with strong performance and easy maintenance, through an incremental migration, with no big-bang.

Fast and stable again: no blockages and no errors at every step
Much easier maintenance: and cheaper in the long run
Integrates with what you use today: ready to connect with modern tools
Scalable: ready to grow, with no rewrites
No big-bang: you keep working while we modernize
You own the code: you escape vendor lock-in

Quick Clean

From Wix to Next.js, without losing Google rankings

At launch, measured with Google PageSpeed Insights: performance 100 on desktop and 96 on mobile, with 100 for accessibility, best practices and SEO on both. CLS 0. Image footprint cut from 83 MB to about 7.4 MB, a clean architecture with around 22 indexable pages. SEO parity preserved: 1:1 URLs and metadata, 21 verified redirects, validated JSON-LD. Clean cutover: uninterrupted email, HTTPS, zero downtime, with rollback available. Post-migration traffic is in its first observation window (4 weeks against the GSC baseline), with a defined alert threshold; at publication it is too early for traffic figures, and the methodology is built precisely to protect them. The old Wix subscription is closed only after stabilisation is confirmed.
