What you're seeing
Your monolith is slowing the team down — deploys are scary, scaling is wasteful, and team boundaries don't match the code.
Our approach
We carve services along the right seams, introduce an API gateway + event bus, and migrate incrementally with no production outage.
Symptoms teams come to us with
- A legacy stack where every change is risky and slow
- Poor SEO and slow first paint from a client-only SPA
- Hiring is hard because nobody wants the old framework
- A big-bang rewrite has stalled or scares everyone
How we de-risk it
- Route-by-route strangler-fig migration, no big-bang launch
- SEO and data parity verified at every step
- Feature flags so old and new run side by side
- A clean decommissioning checklist for the old system
Concrete deliverables, no fluff
Every engagement ends with measurable, documented outcomes — no black-box agency reports.
- Migration plan with route-by-route mapping
- Incremental cut-over, no big-bang launch
- Data + SEO parity verified at every step
- Decommissioning checklist for the old system
From brief to shipped fix
A transparent, low-risk process — a senior engineer reads your brief personally, and nothing starts until you approve a written plan and price.
01
Diagnose
A senior engineer reviews your brief, reproduces the issue, and pinpoints the real root cause — not the symptom — before any code is touched.
02
Scoped plan & quote
You get a written plan to migrate Monolith to Microservices, a firm timeline, and a fixed quote. Nothing starts until you approve it — no surprise invoices.
03
Ship the fix
We implement on a branch and open a pull request you review, working to your code-review standards on your repo — never a black box.
04
Verify & hand off
We verify on staging and production, share before/after evidence where it applies, and leave you a short hand-off note so the fix sticks.
Why teams hand this task to Krapton
Senior engineers only
Your brief is read and handled by a senior engineer — no junior hand-off, no sales-rep filter in between.
Root cause, not a patch
We reproduce and fix the underlying cause, then add a guard so the same class of issue does not quietly return.
Your repo, your standards
Every change lands as a pull request you review, on your repository, following your existing review process.
NDA on day one
Confidentiality and IP are covered before we look at a single line of code. All work stays in your accounts.
Fixed quote up front
You approve a written plan and price before work starts. If scope changes, we re-quote in writing — no surprise invoices.
Proof, where it applies
Performance, SEO and reliability work ships with before/after evidence so the result is measurable, not anecdotal.
Three ways to engage
No retainer required. Pick the model that matches the work — pricing for this task starts from $3,500, with a fixed quote before anything starts.

A focused 1–2 week sprint when the work is bigger than one fix but smaller than a full project.
