Android Developer
Babel Sistemas de InformaciĂłn

Currently working mainly in two projects of Santander Deutschland performing maintenance and evolution of both applications. Occasionally in projects of other customers. 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 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.
