Modernize existing software without starting over
We improve, migrate and rebuild websites and applications that have become slow, fragile or hard to change, in stages, keeping what works and protecting your search rankings.
Software modernization is improving an existing website or application by speeding it up, migrating it, restructuring it or rebuilding parts of it, while keeping what already works and what search engines already know about it.
Most modernization projects do not need a rewrite. They need a diagnosis: what is actually slow, fragile or limiting, and what can stay. A full rebuild is sometimes the right answer, but it should be a conclusion, not a starting assumption.
The work covers three common cases: a slow production application, a WordPress site that has become the constraint and a dated frontend that is hard to extend. Each one is measured before and after, and migrations treat search preservation as a deliverable rather than a hope. The one measured figure on this site is a 30% Core Web Vitals improvement on Sunhub, a production React marketplace; its project page documents what changed.
What this service is actually solving
Nobody recorded where the application started
If there is no baseline, nobody can say whether the work helped, and the improvement becomes a matter of opinion. Measurement first is not process theatre. It is the only thing that makes the result checkable.
The redirect map is treated as a checkbox
Every indexed URL on the old site needs an explicit, tested destination, not a wildcard that happens to catch most of them. The pages that fall through are the ones nobody thought to check.
The bottleneck is not where the team assumed
Most "React is slow" reports turn out to be network and asset problems rather than render problems. Reaching for memoisation before opening the network panel is how a week disappears into changes nobody can feel.
A rebuild is proposed when a staged fix would do
A rewrite blocks feature work for a quarter. Restructuring a working application in shippable slices usually delivers the same result with less risk.
Who this is for, and who it is not
Naming the wrong fit saves both of us a call. If your situation is in the right-hand card, say so and we will point you somewhere better.
- A production React or Next.js application that has become measurably slow
- A WordPress site with real organic rankings that has become slow, fragile or expensive to maintain
- A dated frontend that is hard to extend or no longer works well on mobile
- A legacy interface that needs improving in stages without stopping feature work
- A team that needs the improvement attributable, not just asserted
- A site that is working fine, with no performance or maintenance problem
- A migration wanted only because the new framework is newer
- Slowness that comes from the backend or infrastructure rather than the frontend
What you get
Concrete outputs, not activities. Everything here is something that exists at the end of the engagement.
A measured baseline and a ranked diagnosis
Lab data, and field data where traffic allows, captured before any change, and the causes ordered by impact in writing.
Performance and Core Web Vitals fixes
Bundle and dependency work, rendering strategy, asset and font delivery and a third-party script audit, in isolated changes.
WordPress to Next.js migration
Content, media and structured data moved across, with WordPress kept as a headless CMS where the content team needs it.
Redirect map and search preservation
A URL-by-URL redirect map, canonicals, sitemap and robots rules reconfigured so the rankings the site earned survive the move.
Staged frontend modernization
Refactors delivered in shippable slices, with a rebuild only where the diagnosis justifies one.
A staged, monitored release
Cutover checked at each stage, then Search Console watched after launch with a defined response if anything needs a recrawl.
A second measurement
The same instrumentation run again, with the change attributable to specific work rather than to the engagement as a whole.
How it runs
Audit
Measure the baseline and crawl the current site: URLs, content, structured data, redirects already in place and indexation status.
Plan
A written plan: what to improve in place, what to migrate, what to replace, and the redirect map and release sequence.
Change in stages
Changes land one at a time where practical, built alongside the live site so its uptime and rankings are unaffected.
Release carefully
A staged cutover with status codes, canonicals and rendered content verified at each step rather than assumed.
Measure and monitor
The same tests run again, with the before and after recorded, and indexation watched in the weeks after launch.
How it is built, and why that matters to you
Diagnosis-led and framework-honest. Most of the work is removal rather than addition, because the cheapest asset is the one that is not shipped. Next.js on Vercel is the usual migration target, with WordPress staying as a headless CMS when editors need it.

Where the scope starts and stops
Stated up front so it is a shared understanding rather than a negotiation halfway through.
- Baseline measurement and a written, ranked diagnosis
- Frontend fixes across bundle, rendering, assets and third-party scripts
- URL inventory, redirect map, content and structured-data migration
- A second measurement attributing the change
- Post-launch indexation monitoring for an agreed period
- Backend, database or infrastructure performance beyond its frontend impact
- Guaranteed Lighthouse scores or guaranteed ranking positions
- Content strategy or copywriting beyond migrating what already exists
- Ongoing WordPress plugin or theme maintenance, unless agreed separately

Common questions
Yes, if the migration treats search preservation as a deliverable rather than a hope. Every indexed URL gets an explicit redirect, canonicals and structured data are rebuilt to match what the old templates emitted, and indexation is monitored after launch. Rankings are lost by migrations that skip these steps, not by the framework change itself.
Every URL from the old site is inventoried, from the sitemap, from Search Console and from a crawl, and mapped to its exact destination with a 301. Pattern rules are used only where they genuinely apply.
Yes, if that matters. Keeping WordPress as a headless CMS behind the new frontend is a legitimate option, decided at the audit stage rather than assumed.
A rebuild makes sense when the structure itself is the constraint: the offer is unclear, mobile is weak, or adding a page needs a developer every time. If it simply looks a few years old, or is slow for fixable reasons, a staged fix is usually the better use of the budget.
No, and any such guarantee deserves suspicion. A score varies with the device, the network and the test conditions. What we commit to is a measured baseline, a ranked diagnosis and a second measurement, so the change is attributable whatever the number ends up being.
An aggregate improvement measured before the optimization work began and again after it shipped, on a production React marketplace. It is not a claim about one specific Core Web Vital, and per-metric numbers are not published because the workings for them are not. The project page lists what changed.
Is your current system holding you back?
Send the current site or application. We will reply with what we think is slow, fragile or limiting, what can stay and what we would change first.
- You send the project contextThe current site, a Figma file, a repository, API notes, or a few lines describing the problem. It does not need to be a finished brief: whatever exists is enough to start from.
- We review the problem, constraints and likely scopeA real read of what is actually in the way, what it would take to fix, and whether it is smaller than you were expecting. No call needed to get this far.
- We reply with the recommended next stepWhat we would tackle first, and what we would need in order to estimate it properly. If we are the wrong fit, we will say so and point you somewhere more useful.
