## What I'm looking for

```text
I'm looking for a QA or Business Analyst role bridging business needs and quality software. At Globant, I designed and executed 150+ test cases for the LA Clippers + Intuit Dome app and refined user stories and acceptance criteria in Scrum. In my latest project, CatApp, I took a SaaS product from requirements to production with automated Playwright testing.
```

## About

```text
I designed and developed CatApp end to end as a mobile-first, multi-tenant SaaS PWA for nail salon businesses. Its core modules include appointment scheduling, client management, finance, and inventory.

For CatApp, I implemented tenant isolation, a backend using Server Actions and the repository pattern, and integrations with Google People and Calendar APIs. I also designed a testing pyramid that includes unit, integration, and Playwright end-to-end tests.

I developed DictaMed, a mobile-first healthcare PWA for triage and emergency care, with a FastAPI backend and a React frontend. I integrated voice recognition for clinical dictation and the Anthropic Claude API to generate triage notes and clinical records.

At Globant, I designed and executed more than 150 test cases for the LA Clippers + Intuit Dome mobile application. I performed functional, regression, smoke, and accessibility testing, and validated API integrations using Postman and Bruno API.
