Test Automation Projects
Real frameworks. Real code. Real results.
AWS Landing Zone + Guardrails
Flagship cloud/platform project: AWS Organizations landing zone implemented with Terraform, CI plan/apply gates, cost guardrails, and ops-focused documentation.
Problem
Most personal AWS projects show services, but not governance. Architect roles require multi-account strategy, guardrails, auditability, and controlled change.
Solution
Built an AWS Organizations landing zone with Terraform modules, SCP guardrails, centralized audit logging, and a gated CI workflow.
Key Results
- Gated Terraform CI (plan on PR, apply via approvals)
- Audit trail foundation (org CloudTrail + centralized logging)
Quality Telemetry Dashboard
This portfolio’s flagship demo system: a quality dashboard fed by CI artifacts with an optional AWS-backed ingestion path (safe fallbacks + receipts).
Problem
CI signals are often hard to consume. Teams need a fast, reliable view of test health + trends with proof links.
Solution
Built a telemetry dashboard with snapshot/live/cloud modes, safe fallbacks, and evidence exports (AWS receipts) to prove the system is real.
Key Results
- Live-style health table across repos with safe fallbacks
- Artifact-backed metrics ingestion (GitHub Actions)
Selenium Python Framework
Built comprehensive Selenium + Python framework using Page Object Model, pytest fixtures, and Allure reporting for The Home Depot.
Problem
Manual regression testing took 4+ hours per release across POS, inventory, and e-commerce systems. Tests were fragile and hard to maintain.
Solution
Built comprehensive Selenium + Python framework using Page Object Model, pytest fixtures, and Allure reporting. Implemented smart waits, reusable components, and parallel execution.
Key Results
- 70% reduction in regression testing time (4 hours → 75 minutes)
- 300+ automated test cases covering critical user flows
API Test Automation Framework
Built layered architecture with smart retry on 429/5xx errors, Pydantic validation, and session pooling for 3x speed improvement.
Problem
Flaky API tests failing randomly in CI due to network issues and rate limits. No schema validation meant API changes broke silently.
Solution
Built layered architecture with smart retry on 429/5xx errors, exponential backoff, Pydantic models for type-safe validation, and session pooling for 3x speed improvement.
Key Results
- Flaky test rate: 10% → 0.8% (92% reduction)
- 125+ API tests with 90% endpoint coverage
CI/CD Testing Pipeline
Built containerized testing infrastructure on Kubernetes with parallel execution, reducing CI/CD pipeline time by 82% while processing 500+ tests per build.
Problem
45-minute CI/CD pipeline bottleneck blocking 30 developers. Sequential test execution, manual scaling, and unreliable Jenkins infrastructure causing daily frustration.
Solution
Built Kubernetes-native testing infrastructure with Docker containerization, matrix parallelization across 10 job groups, and auto-scaling HPA. Implemented smart test grouping and comprehensive monitoring.
Key Results
- Pipeline time: 45 min → 8 min (82% reduction)
- Builds per day: 50 → 200 (4x increase)
Performance Testing Suite
Built comprehensive performance testing infrastructure using JMeter and Locust, identifying 3 critical bottlenecks and improving API response times by 40%.
Problem
No performance testing meant slow APIs (2.5s response), frequent timeouts (5%), and fear of traffic spikes. System could only handle 500 concurrent users.
Solution
Built comprehensive performance testing suite using JMeter and Locust. Implemented distributed load testing simulating 10,000 users, identified 3 critical bottlenecks, and optimized database queries.
Key Results
- API response time: 2.5s → 1.5s (40% faster)
- Max concurrent users: 500 → 10,000 (20x capacity)
Mobile Testing Framework
Built comprehensive Appium + Python framework supporting 15+ device configurations, reducing regression testing from 2 days to 2 hours with parallel execution.
Problem
Manual mobile testing took 2 days per release across 15+ device combinations. Device-specific bugs escaping to production. App rating dropped to 3.2 stars.
Solution
Built cross-platform Appium + Python framework with Page Object Model. Integrated BrowserStack for real device testing. Implemented parallel execution and visual regression testing.
Key Results
- Regression time: 2 days → 2 hours (96% faster)
- Device coverage: 5 → 15 devices (3x more)
BDD Cucumber Framework
Built Cucumber BDD framework with Gherkin scenarios enabling product owners to read and contribute to test cases, improving collaboration and test coverage by 40%.
Problem
Communication breakdown between technical and non-technical stakeholders. $500K in rework from requirements misunderstandings. Compliance audit failures.
Solution
Built BDD framework with Cucumber/Gherkin enabling stakeholders to write executable specifications. Implemented 'Three Amigos' sessions for collaborative scenario writing.
Key Results
- Requirements clarity: 50% → 95% (+45 points)
- Rework cost: $500K → $50K (90% reduction)
Visual Regression Testing Suite
Built automated visual regression testing framework using Percy.io and Selenium, reducing manual visual QA from 8 hours to 45 minutes while maintaining 99.2% test stability.
Problem
Manual visual QA took 8 hours per release across 144 test combinations (3 viewports × 4 browsers × 12 flows). Visual bugs slipping to production, costing $50K per incident.
Solution
Built automated visual regression testing framework using Percy.io and Selenium. Implemented intelligent screenshot comparison with dynamic element hiding, cross-browser support, and CI/CD integration.
Key Results
- Manual visual QA: 8 hours → 45 minutes (94% reduction)
- 47 visual bugs caught pre-production in 6 months
Security Testing Suite
Production-grade security testing framework implementing OWASP Top 10, API security validation, and secrets detection. Discovered 23 critical vulnerabilities before reaching production in a fintech platform processing $50M+ daily.
Problem
Fintech company processing $50M+ daily had no automated security testing. Manual security audits took 40 hours and found issues too late. 23 critical vulnerabilities reached production in 6 months.
Solution
Built comprehensive security testing framework with OWASP Top 10 automated testing, API security validation (JWT, rate limiting, CORS), secrets detection, and CI/CD integration. Implemented intelligent retry logic and type-safe validation.
Key Results
- 23 critical vulnerabilities caught pre-production
- Security audit time: 40 hours → 2 hours (95% faster)
