About Jam

Too many critical bugs in production or a lack of visibility on quality?

I help product teams better manage their risks, secure their releases, and gain confidence before each release.

QA with +5 years of experience, I have completed +35 projects on Malt with consistently excellent customer feedback.
I support SaaS, e-commerce, and digital product teams, including those on critical environments (payment, booking), across the entire testing chain:

✔ QA Strategy & Test Organization
✔ Implementation of Automated Tests (Cypress, E2E, API)
✔ Functional & Non-Regression Testing
✔ Quality Monitoring, Reporting, and KPIs

🚀 I also work on improving quality processes:

• Creation of internal tools (Slack, Notion, API) to structure incident management
• Centralization of bugs and incidents with real-time monitoring
• Implementation of quality KPIs and incident mapping
• Improvement of communication between support, product, and technical teams

🎯Results: reduction of critical bugs, smoother releases, and increased confidence in product quality before each deployment

🧠 Autonomous, rigorous, and product-oriented, I easily integrate into your teams with a collaborative and constructive approach.
