Worked on a complex custom HR solution built with Quasar framework and Ruby
on Rails that is used by large European companies such as Edeka Nord, Omexom, Total Energies, and Bundesdruckerei. Improved my skills in complex problem-solving from scratch, using up-to-date UI/UX approaches for building a complex system, learned Ruby on Rails and practiced it by creating new bits of functionality on the back-end side, covering it with back-end tests and Cypress front-end E2E tests, using the GraphQL for sending the data between front and back-end.
Barcodesinc.com (Magento, Kohana PHP framework, Javascript)
Worked for a big B2B barcode equipment store with some bits of legacy Kohana framework code. Improved my communication and task management skills by being proactive during feature planning and suggesting UI/system improvements. Reduced costs for supporting the main barcodesinc.com store by upgrading the outdated legacy front-end to use the Bootstrap responsive layouts and removing the separate mobile website being supported by a 3rd party team.
