u/Goldtec_II

Looking to further advance my career. I graduated in 2019 with a math and computer science degree (essentially entry level data analytics focus). Learned basic python but at this point I am well without practice so I cannot say python is one of my skills. I work in the payments industry relative to POS systems and e-commerce. I feel stuck at my role and not many similar companies are hiring for similar roles. I would like to further my education and get a masters but am wondering what would be beneficial in the current climate. I am very open to fully diverging from stem but I do generally enjoy things like math, helping people, problem solving, being active.
Any thoughts or recommendations?

Hello, first time going to Korea in October for 12 days.
Getting scared off by people mentioning not to try visiting 3 cities. Wondering what others think.
We want to spend most of our time in Seoul and 4 or 5 days in Jeju. Is 4 days for Jeju enough?
Do we have time to fit in a 3rd city like Busan? What do people recommend and are there itineraries anyone recommends for a 12-day Seoul/Jeju trip?
