WORK EXPERIENCE
QA Engineer — PortalTop (Real Estate, Spain) May 2024 – May 2026
• Performed functional, GUI, and usability testing of a real-estate web platform across web and mobile.
• Designed and maintained detailed test cases and checklists in TestRail/Zephyr, applying test design techniques —
equivalence partitioning, boundary value analysis, decision table testing, state transition testing, and exploratory testing
— to cover property search, filtering, and booking flows.
• Reported and tracked 700+ bugs in Redmine and Jira, including 65 critical and 180 major defects caught before reaching
production.
• Validated REST API endpoints in Postman against Swagger specifications (HTTP methods, status codes, response
structure) and ran basic SQL queries to verify data consistency, identifying backend issues before the UI testing stage.
• Identified and isolated a critical frontend state-rendering defect in the interactive map search (a persistent visual artifact
after drawing custom zones, closing results, and reloading); diagnosed it via Chrome DevTools and Postman and provided
reproduction steps that enabled the dev team to fix the map UI state synchronization issue, improving search reliability.
• Automated frontend regression scenarios in Cypress (JavaScript), including an E2E test covering the map search flow,
reducing manual regression testing time by approximately 30%.
QA Engineer — Center-Auto Jan 2023 – Aug 2023
• Performed manual testing of web and mobile platforms, executing test cases and reporting defects in Jira.
• Carried out basic verification of REST API endpoints in Postman, checking core HTTP methods and response codes.
• Gained initial hands-on exposure to test automation concepts, laying the groundwork for later work with Cypress.
