What I'm looking for

Busco integrarme a equipos ágiles donde pueda garantizar calidad en banca/fintech con foco en E2E (web/mobile), API Testing y validaciones de datos. Me motiva liderar casos negativos/edge cases, sostener regresión y colaborar con Dev/PO/UX.

Me especializo en testing funcional E2E (web/mobile) para plataformas financieras, con foco en flujos críticos de banca digital. Validamos APIs e integraciones, reglas de negocio, estados y manejo de errores, asegurando consistencia entre UI y API.

En mi experiencia gestiono defectos en Jira (evidencia, severidad/prioridad, seguimiento y re-test) y doy soporte a UAT y releases. Diseñó y ejecuto casos positivos, negativos y edge cases, incluyendo smoke y regresión para reducir riesgos operativos.

Además, realizo validaciones de datos con SQL y preparo/armo datos de prueba (incluyendo data validation). Trabajo validando REST APIs, status codes, idempotencia e integridad de integraciones, y uso Postman para pruebas de APIs.

Trabajo en entornos ágiles (Scrum/Kanban) con Dev/PO/UX, usando prácticas de testing basadas en riesgos (enfoque ISTQB) y apoyo con Python/pytest para automatizar y fortalecer regresión de APIs.
