QA-as-a-service for teams that ship weekly
We started ZeroBugLab after watching engineering teams burn cycles firefighting production escapes and flaky CI pipelines. Quality was an afterthought, bolted on after code freeze—never embedded in the sprint.
We built a different model: QA engineers who embed with your team, instrument your CI/CD, and hold the line on delivery quality—so you ship fast without breaking trust.

Founder & CEO — Hussain Mohammed
ZeroBugLab was founded in Australia by Hussain Mohammed, a delivery and quality leader with over 15 years of experience owning release outcomes for high-change engineering teams across APAC.
Before building ZeroBugLab, Hussain operated at the intersection of engineering, delivery, and quality in environments where failure was visible and speed was non-negotiable. His experience spans airlines, proptech, fintech, and large consumer platforms, including leadership roles at AirAsia, Instahome, REA Group Asia, iCar Asia, and PETRONAS ICT.
Across these organisations, Hussain consistently saw the same problem: teams invested heavily in QA tools and automation, yet still struggled to ship reliably. Quality was measured, reported, and discussed—but rarely owned as a system. Releases remained unpredictable, regressions grew, and accountability diffused across teams.
ZeroBugLab was created to fix that.
The company embeds quality directly into delivery—instrumenting CI/CD pipelines, enforcing outcome-based release standards, and placing experienced engineers alongside product teams. Rather than acting as a gatekeeper, ZeroBugLab operates as a delivery partner, accountable for real metrics such as regression time, flake rate, change-fail rate, and release readiness.
Hussain continues to lead ZeroBugLab with a clear mandate: turn quality from a downstream cost into a strategic advantage, enabling teams to ship weekly with confidence—without slowing velocity or relying on heroics.
"Quality shouldn't be a cost center. It's a competitive advantage. When QA is embedded in your sprints—not bolted on at the end—everything changes: faster releases, fewer escapes, and teams that actually trust their deployments."
— Hussain Mohammed, Founder
The CQ Operating Model™
We've codified our approach into a repeatable framework: the Continuous Quality Operating Model. It combines:
- →Shift-left gates: Contract tests, unit tests, and integration tests catch defects in PR review—before they reach staging.
- →Parallel execution: Full regression suite runs in <30 minutes, unblocking daily releases.
- →SLO-based gates: Flake rate <2%, coverage >80% on critical paths, change-fail rate <2%.
- →Embedded QA: Our engineers join your standups and PR reviews—they're part of your team, not external gatekeepers.
- →Live telemetry: Real-time dashboards show escapes per release, coverage delta, and flake trends.
The result: teams ship weekly with confidence. No heroics. No production fires. Just predictable, quality-assured releases.

Operating principles
Shift-left, not shift-blame
We catch defects in PR review and staging—not production. Contract tests, chaos drills, and SLO gates are our guardrails.
Speed is a quality metric
Regression in <30 minutes. Flake rate <2%. We optimize for velocity without cutting corners on coverage.
Observability over blind faith
Every release comes with telemetry: escapes per deploy, coverage delta, flake trends, and change-fail rate.
