Quality engineering for teams that need proof, not confidence theater. I design Playwright, mobile, API, a11y, and performance checks that turn release risk into visible signals.

ABOUT ME
About Me
I'm a Quality Engineering Lead with 8+ years of experience building automation solutions that prevent bugs, reduce costs, and accelerate delivery. When I'm not crafting test frameworks, you'll find me gaming, watching anime, or spending time with my family.
I'm passionate about solving complex quality challenges and helping teams ship reliable software faster. Whether you need to scale automation, modernize legacy test suites, or build QA processes from scratch—let's connect.
01
What drives me
I believe quality engineering is about empowering teams, not just finding defects. I've reduced test costs by 80%, mentored QA engineers into senior roles, and built automation frameworks that achieve 99% stability across mobile and web platforms.
02
My approach
Strategic automation backed by solid documentation. I've led cross-platform projects (iOS, Android, Web) using Playwright, Espresso, XCUITest, and WebDriverIO—always prioritizing maintainability and business impact over flashy metrics.
What I bring
01Cost efficiency: Reduced implementation costs by 50% while increasing coverage to 80%+
02Leadership: Built career development programs and mentored teams to level up their skills
03Versatility: Fluent in E2E, API, accessibility (WCAG 2.2), and performance testing
04Innovation: Exploring AI-powered testing workflows to accelerate QA delivery
01 / Certified
ISTQB CTFL 4.0 (2023)
02 / Education

03 / Languages
English (C1 - Highly Proficient), Spanish (Native)
WHAT I DO
QA operating system for release risk
Each module is built to answer one question: what can break, how fast can we detect it, and who needs the signal?
e2eregression mapped
Automation Architecture
Design Playwright, WebDriverIO, Cypress, Espresso, and XCUITest suites around stable flows, clear fixtures, and release gates teams can maintain.
perflimits visible
Performance Testing
Use JMeter, k6, and focused profiling to expose slow paths, load limits, and user-facing degradation before traffic finds them.
a11ybarriers removed
Accessibility Audits
Audit WCAG behavior with clear acceptance criteria, keyboard coverage, semantic markup checks, and practical remediation notes.
apiside effects checked
API Testing
Cover the backend seams behind the UI with contract, integration, and payment-flow checks that fail before the browser does.
riskowners aligned
QA Strategy
Turn scattered QA activity into risk models, test plans, reporting, and ownership that product and engineering can act on.
teamteam unlocked
Mentorship
Help QA teams write better cases, debug automation, review pull requests, and explain quality risk without hiding behind dashboards.
FREE QA STARTER LIBRARY
Downloadable automation repos for teams starting from zero.
I packaged the automation patterns I use with teams into public starter repos. Pick a framework, download the zip, run the smoke suite, and start from a structure that already includes CI, reports, docs, and a local demo target.
Short, practical breakdowns from the same work I use in release reviews: CI/CD gates, Playwright workflows, and the habits that make automation useful.
Let's discuss how I can help your team deliver exceptional software experiences. Whether you need test automation, performance optimization, or QA strategy consulting.
