Currently working mainly in two projects of Santander Deutschland (Santander Banking and SantanderSign) performing maintenance and evolution of both applications. Occasionally I collaborate on other projects that require additional assistance, like Renfe Ticket. Regarding the applications of Santander Deutschland:
- I improved the stability of the application by increasing the percentage of error-free sessions from 82% to 99.4% in two months.
- I increased the code coverage from 37% to 81% by doing instrumental and unit tests.
- Code refactoring: increase readability and improve the structure of the code; technical and functional documentation; improvements in smoothness and speed.
- I make sure that the mobile banking application is always up to date in terms of library versions in order to take advantage of the new functionalities that are included.
- I improved the security and integrity of the application by performing actions such as: encrypting sensitive user information, avoiding the use of modified devices and code obfuscation.
- I created two data mocks, one static and one dynamic. I made them because of the limitations to connect to pre-production environments. Both are written in Golang.
