A bit of everything, please: translation from and to the business, data science, GenAI, SQL magic, engineering, architecture, testing, and QAโ€”whether itโ€™s for streamlining logistics ๐Ÿšš, improving marketing efforts ๐Ÿ“Š, or empowering buying as a frontrunner ๐Ÿ›๏ธ. Super exciting and fun, all while keeping a sharp focus on the business perspective and tangible benefits. ๐Ÿ”Ž

Dear Diary,
while we are working remotely for the most part, I enjoy office days starting off early in the canteen having a coffee and breakfast at times, meeting colleagues, checking emails, and preparing the day; the industrial yet modern flair is awesome. I specifically value our on-site sprint changes kick-starting next adventures, or exchanging with the amazing team here at ALDI DX’s International Data & Analytics. We are changing retail.
