QA Architect · Napptilus Tech Labs

INDITEX · May 2025 – Dec 2025

Android Mobile QA Architect responsible for quality strategies at INDITEX.
Defined from scratch the analytics testing strategy on Android (Espresso + Kotlin) aligned with iOS, implementing a POM architecture able to verify analytics events fired during execution and validate each of their attributes.

Lead QA Engineer · Napptilus Tech Labs

ZARA (Inditex) · Aug 2023 – Apr 2025

Created and led ZARA's Android automation framework from scratch with Espresso (Kotlin), reaching a suite of over 350 tests run as a weekly regression, with an initial team of 3-4 people.
Designed the framework architecture following the Robot Pattern, using TAGs as locators instead of identifiers for better decoupling and maintainability.
Integrated TrackingPlan into the framework to verify analytics events; given the limitations of the third-party software, I later designed my own analytics architecture from scratch.
Integrated Applitools for visual validation of components and their structure within each view, solving UI testing coverage without manual assertion logic.
Use of ADB from the terminal.
Analysis and interception of requests with Charles and Postman.
