We apply a proven QA methodology built on the 70-20-10 testing pyramid: 70% API and backend validation, 20% integration testing, and 10% end-to-end UI verification. From test planning and defect tracking to release gates and client sign-off, we embed quality checks at every stage of the development cycle to prevent costly rework and ensure a confident, on-time launch.

Multi-platform coverage across mobile, web, and API layers
Release-ready artifacts including test plans, defect reports, and sign-off documentation
Example deliverables
- Manual & automated testing across platforms
- API & integration validation
- Release management & sign-off
The 70-20-10 Testing Pyramid
Right-sized approach for maximum coverage with minimum maintenance.
70%
70% API & Backend
The bulk of testing happens here. We validate endpoints directly — it is fast, catches logic errors instantly, and ensures data integrity before it ever reaches the UI.
Faster / CheaperSlower / Costlier
20%
20% Integration
Verifying the handshake between systems. Does the admin panel sync with the frontend? Do API triggers fire correctly when data changes?
Faster / CheaperSlower / Costlier
10%
10% UI & E2E
Focus on Critical User Journeys that drive revenue. We validate the core paths on real devices because UI-level tests catch what users actually see.

The Continuous Quality Cycle
We do not just test at the end. We integrate quality checks at every stage to prevent costly rework.

Quality
Shielding Users
QA finds issues before your users do. We simulate real-world usage — bad networks, old devices, and edge cases beyond the happy path.
Defining Done
We verify features against strict requirements. If it crashes, glitches, or looks wrong, it is not done.
Preventing Regressions
New code should not break old features. We re-test critical flows with every update to ensure stability.
Testing Phases & Gates
A structured 4-step quality assurance process to de-risk the release.
Phase 1
Smoke Test
Rapid sanity check ensuring the build installs, launches, and critical paths are not blocked.
Entry Criteria
- New build deployed
- Environment accessible
Exit Criteria
- Installation successful
- Login works
- Zero blocker crashes
Phase 2
Functional
Deep dive into new features against requirements. Validating logic, UI states, and API responses.
Entry Criteria
- Smoke test passed
- Test data prepared
Exit Criteria
- All P0/P1 bugs logged
- Features meet spec
- API contracts valid
Phase 3
Regression
Ensuring recent changes did not break existing functionality. Focused on side-effects and stability.
Entry Criteria
- Feature complete
- Critical bugs fixed
Exit Criteria
- Core flows stable
- No regressions found
- Release candidate tagged
Phase 4
UAT & Sign-off
Client validation. Verification of business value and readiness for real-world usage.
Entry Criteria
- Internal QA sign-off
- Known issues list
Exit Criteria
- Client approval
- Go / No-Go decision
- Launch ready
