QA Engineer with a designer's eye

I build testing systems that catch bugs others miss, because I understand both code and user experience. 10+ years engineering quality into digital products.

What can I do for you?

Let's get straight to the point.

I test functionality AND user experience, catching issues where technical execution meets user flow
I design QA strategies from scratch, establishing processes that help teams ship faster without breaking things
I read code to detect issues early. Understanding architecture helps me find problems before they reach production
I work with modern tools (Selenium, Cypress, JIRA, Git) but my value is the hybrid perspective: design + tech + QA

Where technical quality meets user experience

My curiosity about how systems work led me to Quality Assurance engineering. That transition became my edge.

Most QA professionals test if features work. I engineer systems to ensure they work AND make sense. I design test architectures, build automation frameworks, and establish quality processes, but my differentiator is catching issues where technical execution meets user flow.

I've spent 10+ years engineering quality strategies for complex digital products: e-commerce platforms handling millions of transactions, fintech apps, media applications. I architect test frameworks using Selenium and Cypress, integrate CI/CD pipelines, and establish quality gates, but the real value is my hybrid perspective.

A feature can pass every functional test and still create a terrible user experience. I'm the engineer who catches that disconnect.

If you need QA engineering that goes beyond "does it work?" to "does it make sense?"
let's talk.
