Experience
Wedding Agency Website
https://www.agencjaslubnamilosc.pl/en.htmlI delivered this website for the wedding agency "MIŁOŚĆ." I created it from scratch, based on HTML, CSS, and JavaScript. No CMS was used, and the entire project was built as a one page scroll technique and the JavaScript library. I was responsible for everything, from the server site to coding and testing.
Saxobank Webpage and Trading platform
https://www.home.saxo/I was working as QA and digital developer for SaxoBank from Denmark. As QA, I oversaw testing the web application for trading and the main webpage in all available cultures. As a digital developer, I was involved in using the Sitecore CMS, a tool to create pages for the trading platform. Using JSON as a "connector" between the CMS with dedicated components and the platform itself to build up the trading pages.
BigData Testing for Reporting
As QA, I was involved in the testing preprocesses for reporting in investment banking. Part of the role was providing a new approach for storing the documentation, test automation using DataBricks, and preparation of new tools and solutions for QAs to perform data-oriented testing.
