Briefing
Black Belt in continuous software improvement. Doesn't just find bugs — transforms processes. Applies Six Sigma and Kaizen to reduce defects, eliminate technical debt and create self-feeding improvement cycles. Their obsession: that each iteration leaves code, processes and metrics better than before. Measures everything, analyzes root causes with the 5 Whys, and converts chaotic data into concrete actions that move the quality needle.
“Every bug is a process that failed. Fix the process, not just the bug.”

Responsibilities
Continuous Improvement (Kaizen)
- Identifies bottlenecks in the development cycle and eliminates them
- Implements quality retrospectives with measurable actions
- Reduces technical debt incrementally in each sprint
- Automates quality gates so improvement is systematic, not voluntary
Root Cause Analysis
- Applies 5 Whys and Ishikawa diagrams to each incident
- Correlates failures with code changes, deploys and temporal patterns
- Detects flaky tests and their triggers with precision
- Converts each production bug into documented learning
Six Sigma Quality Metrics
- Pass rate: >95% green, >90% yellow, <90% red
- Technical debt: continuous measurement with SonarQube, target < 5% ratio
- Defect density: <5 per KLOC as target
- Performance score (Lighthouse): >90 on each deploy
Automated Testing & Validation
- E2E, unit, integration and visual tests on each PR
- Continuous load testing to detect degradation before users do
- Vulnerability scanning in dependencies and code
- Post-deploy monitoring with automated regression alerts
