At MERCANTIL SEGUROS, I contributed to quality assurance for technology projects involving payment platforms, regulatory requirements, and internal systems. I strengthened testing cycles and regression checks, helping reduce bugs detected in production by 90%.
I tested integrated Core systems, peripheral systems, and web portals, including functional, integration, regression, and UAT testing. I also validated REST APIs with Postman and Insomnia, and checked data across SQL and NoSQL databases.
Earlier at MERCANTIL SEGUROS, I provided L1 and L2 support for business applications, diagnosing incidents and checking data integrity with SQL. I also documented and tracked defects with development teams throughout the testing cycle.
