Business × Data × AI

Building a career worth having, in the age of AI.

Hi, I’m Diem — a Business Analyst based in Finland, working at the intersection of business, data and technology.

I’ve spent the past decade moving between banking, data, analytics and entrepreneurship. Now I’m exploring how AI is changing the way we work — and what a good career looks like when the rules are changing.

Still learning, still building, writing as I go.

01 — About

My story, so far

I spent years building a career in corporate — until I took a leap and opened a small retail shop.

A few months in, I realised it wasn’t the life I wanted. Selling the business was unexpected, but it changed the way I think about work, freedom, and what a successful career actually means.

Now I’m building my next chapter — staying curious about AI, experimenting with new ways of working, and figuring things out as I go.

Let’s talk

I’m always interested in conversations around career transitions, AI and the future of knowledge work, building things from scratch, or simply figuring out what comes next.

If something here resonates, say hi.
