Hey, Mark here. I design QA systems and automation frameworks that shift quality left and keep pipelines stable at scale.
I build automation that actually works
And I lead teams to stop treating QA like an afterthought. 9+ years turning flaky tests into reliable systems, manual testers into automation engineers, and building quality-first cultures through guild leadership.

Demo Theater
Don't just take my word for it—watch me work. Here's a collection of automation demos, strategy breakdowns, and technical deep dives.
The Proof
Numbers don't lie. Here's the measurable impact I've delivered.
60%
Test Flakiness Eliminated
Rebuilt Cypress framework with smart waits, proper selectors, and retry logic. Went from unreliable tests to rock-solid automation.
14x
Regression Speed Increase
Parallelized test execution across Docker containers in Jenkins. What took 2 hours now runs in 8 minutes.
3 Teams via Shadow-Ops
Cross-trained every QA with quarterly Shadow-Ops rotations so any team’s automation can be covered.
100%
Release Validation Accuracy
Zero production rollbacks in 3+ years. Every release validated against acceptance criteria before deployment.
5 Years
Shift-Left Guild Leadership
Taught devs and PMs to embed QA in design phase. Built a self-sufficient quality culture that doesn't rely on QA gatekeeping.
3 Teams
Cross-Trained via QA-SHADOW-OPS
Eliminated knowledge silos with quarterly cross-training program. Every QA can now cover any team's automation.
AI-Driven
BuildGhost R&D Lab
Pioneering next-gen testing tools with AI-powered DOM crawlers and test suite generators to eliminate manual bottlenecks.
AI-Assisted QA:The Future of Testing
I don't just use AI — I build testing workflows around it. AI is the strongest multiplier QA has had in decades, and I treat it like part of the toolchain.
AI-Powered DOM Crawling
Automated selector recommendations, structural analysis, and instant remediation for brittle tests.
Prompt-Driven Test Generation
Cypress, API, and mobile test scaffolds generated through controlled LLM prompts.
LLM-Assisted Visual Diffing
AI-driven comparison and detection of UI drift with reduced false positives.
Intelligent Flake Detection
Self-healing heuristics and automated flake categorization to stabilize pipelines.
AI Risk-Analysis for Sprints
Estimates risk hotspots across PRs and tickets before development even starts.
Auto-Summaries for Failures
AI-generated debugging summaries handed directly to developers for faster triage.
Test Case Grooming Automation
Automatic refinement, deduplication, and rewriting of test cases at scale.
CI/CD Pipeline Codegen
AI-assisted creation of workflows, configs, and validation logic.
TestGhost R&D Lab
My ongoing research project exploring intelligent QA tooling and automated test creation.

Complete Skills Breakdown
Test Automation
Skills:
Cypress (Expert-level)
Playwright
Selenium WebDriver
API Testing (REST/GraphQL)
Visual Regression Testing
E2E Test Architecture
How I Used These:
Built expert-level Cypress automation from scratch at FloSports. Reduced test flakiness by 60% through smart waits, proper selectors, and retry logic. Architected E2E test suites that caught critical bugs before production. Also worked with Playwright and Selenium WebDriver for cross-browser testing. Implemented visual regression testing to catch UI bugs automatically.
CI/CD & DevOps
Skills:
Jenkins Pipeline Optimization
Docker Containerization
GitHub Actions
Linux/Command Line
Test Parallelization
AWS Infrastructure
How I Used These:
Achieved 14x faster regression testing by parallelizing test execution across Docker containers in Jenkins. What took 2 hours now runs in 8 minutes. Managed automation scripts in Linux-based CI/CD environments with command-line debugging. Built GitHub Actions workflows and AWS infrastructure for scalable test execution.
Programming
Skills:
JavaScript/TypeScript
Node.js
Python
SQL
Git Version Control
Code Review & Refactoring
How I Used These:
Expert in JavaScript/TypeScript for test automation. Built Node.js test frameworks and Python scripts for data validation. Wrote SQL queries for database testing. Proficient in Git version control and code review processes. Refactored legacy test code to improve maintainability and reduce technical debt.
QA Strategy & Leadership
Skills:
Shift-Left Testing
Test Strategy Design
Risk-Based Testing
Team Mentorship & Training
Guild Leadership
Process Documentation
How I Used These:
Founded and led Shift-Left Guild for 5 years, teaching devs and PMs to embed QA in early-stage design. Built a self-sufficient quality culture that doesn't rely on QA gatekeeping. Designed "QA-SHADOW-OPS" quarterly cross-training program to eliminate knowledge silos across 3 teams. Created modular Cypress upskilling curriculum with video modules and capstone projects.
Tools & Platforms
Skills:
Jira / Linear
Segment Analytics Validation
Stripe Payment Testing
Datadog Monitoring
Postman / Insomnia
BrowserStack / Sauce Labs
How I Used These:
Led analytics integrity testing with Segment, validating event data accuracy across user flows. Oversaw critical payment funnel testing with Stripe validation. Used Jira/Linear for test planning, Datadog for monitoring, and Postman/Insomnia for API testing. Leveraged BrowserStack and Sauce Labs for cross-platform testing.
Emerging Tech & R&D
Skills:
AI-Assisted Testing
LLM Integration
