Verity
User-reported bugs often lack reproducible evidence for engineering teams. Verity runs Playwright in AWS Lambda to capture screenshots, JS errors, and API failures, then deduplicates and scores issues before GitHub triage.
Dec 2025 - May 2026
Overview
Serverless QA layer bridging feedback and verified bugs at Wamo. Playwright headless in Lambda collects visual and error evidence. AI generates tests from URLs with rule-based fallback when generation fails. Issues dedupe and score before landing in a triage hub. An embeddable widget captures in-context reports with screenshots. Step Functions manage test runs and retests with S3 artifacts.
Role
Full-stack engineer on test runner infrastructure and triage frontend from Playwright Lambda execution through embeddable widget delivery.
Scope
Headless Playwright in Lambda with Chromium layers, AI test generation with rule-based fallback, issue deduplication and confidence scoring, GitHub App integration, and embeddable in-app feedback widget.

Key Learnings
- Running Playwright headless browsers in AWS Lambda with Chromium layers
- Step Functions orchestration for multi-stage test and retest workflows
- Issue deduplication and confidence scoring from visual and error evidence
- Embeddable widget design for in-app bug reporting with screenshot capture
Challenges & Solutions
- Running Playwright reliably within Lambda memory and timeout constraints
- Designing deduplication that groups similar issues without merging distinct bugs
- Orchestrating retest workflows that validate fixes without false positives
Business Impact
- Time from user-reported issue to verified, reproducible bug report dropped significantly.
- Visual evidence capture eliminates manual screenshot requests from QA teams.
- Validated issues push into GitHub workflows through App integration.
Outcome
- Serverless QA platform with Playwright automation at Lambda scale.
- Confidence scoring prioritizes high-signal issues for triage teams.
- Embeddable widget deployable across client applications for in-context reporting.
