Specializing in containerized CI/CD ecosystems and contract testing. I help enterprise teams move from "fragile & slow" to "robust & continuous."
Most test automation captures bugs. Mine captures lost time. Here is the quantifiable impact of my architecture on delivery velocity.
Compressed regression cycles via containerized CI/CD and shift-left contract testing.
Managed <2% flake rate on a national-scale ERP system serving 40k+ facilities.
Improved p95 scores on critical inventory flows through targeted JMeter profiling.
I built XPathy to solve the "Fragile Locator" problem in enterprise Selenium/Appium suites. It replaces brittle, magic strings with a fluent, type-safe DSL that compiles into optimized XPath.
//div[translate(@id, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz')='main-container' and contains(text(), 'Hello World')]
A curated selection of tools and paradigms I use to build resilient quality infrastructure. I choose the right tool for the architecture, not just the trend.

METHODOLOGIES
A timeline of high-impact roles where I’ve consistently improved engineering velocity and quality standards.
Project: Sysco Warehouse Management System (SWMS), the world’s largest foodservice supply chain.
Focusing on API & UI automation: scripting test cases for new features while stabilizing and maintaining existing suites.
Implemented custom Excel Rebate Validator to automate complex rebate regression checks, eliminating manual data validation.
Worked on Vesta, a national-scale healthcare ERP deployed across the Philippines and Nepal.
Increased test coverage to 85% in 12 months, effectively catching regressions before UAT.
Reduced manual regression effort by ~70% through strategic automation of critical patient workflows.
Project: Ride-sharing mobile application (Android/iOS).
Automated critical API and UI workflows, reducing manual testing effort by ~40%.
Executed baseline performance tests for 1,000 concurrent users, resolving key API bottlenecks pre-launch.
Tools I build to solve recurring friction points in the QA lifecycle.
An open-source AI shopping assistant powered by Gemini. Features universal website integration via a simple script tag, secure API handling with Cloudflare Workers, and full customization via JSON.
Context-aware triage tool using NLP embeddings. Scans TFS/Jira history to surface semantically similar past bugs, accelerating Root Cause Analysis (RCA) by ~70%.
Democratizing quality patterns through writing and public speaking.
