Releases took weeks
Every change needed a manual test cycle, so small fixes waited for big release windows.
Shipwise case study

Shipwise ran its core product on a platform their team could no longer move fast on.
Shipwise partnered with TechXntra to design, build and launch a product that scales with their growth. Every release was risky, costs kept rising, and the people who understood the original code had moved on. Standing still was no longer an option.
Cloud costs kept rising
Over-provisioned servers ran around the clock whether customers were active or not.
Fragile legacy code
Tightly coupled modules meant one change could break three unrelated features.
Knowledge in few heads
Only two engineers understood the core flows, and documentation was years out of date.
What TechXntra did
A senior TechXntra squad rebuilt the platform in small, safe releases.
Discovery sprint
Two weeks of interviews, analytics review and a prioritised roadmap.
Architecture review
Every module mapped with its dependencies and risk score.
Design system
A shared component library for web and mobile.
API layer
Clean, versioned APIs in front of the legacy core.
Data migration
Records moved in batches with automatic reconciliation checks.
CI/CD pipeline
Automated builds, tests and zero-downtime deploys.
QA automation
End-to-end tests on every critical customer journey.
Launch and handover
Runbooks, training and a calm, staged go-live.
Discovery often uncovers more than the brief. Here the team found that what looked like one product was really three services sharing one database, and split them cleanly.
Every phase has a senior TechXntra engineer in the loop. They set the scope, review what the tools find, decide what needs a human answer, and turn it into a plan the client's team can trust.
What we delivered
Each release shipped behind a feature flag, was tested end to end, and could be rolled back in one click.
Example release note
Deploy 214 / checkout service / zero downtime / rollback ready / 0 errors
Small, reversible releases are why the client's team now ships every week without late-night incidents.
Rewrites fail when a forgotten rule shows up in production. We find those rules first, confirm them with the client, and only then build. Launch comes faster, with less risk.

Critical incidents at launch
Older codebases are easier targets every year. Fixing the basics early costs a fraction of fixing them after an incident.
Launch guarantee
Two checks take every release from tested to trusted.
Check 1
Automated test suite
Before release
- Unit and integration tests run on every commit
- End-to-end tests cover key journeys
- Performance budgets checked automatically
- Security scan on every build
Journeys covered95%
Check 2
Side-by-side comparison
During launch
- Old and new systems receive the same input
- Outputs are compared automatically
- Any difference becomes a test failure
Parity confirmed100%
Before automation, these checks depended on long manual test cycles. A structured, automated approach is faster and catches more than a manual team usually does.
