> Now Building Under My Own Name
Hi , from MADAGASCAR, I'm Andrinirna (Kors) RAKOTOARISOA, graduated in Software Engineering with a specialization in UI/UX Design — which means I've never seen code and design as separate disciplines. I build both, and I think in both.
For 5+ years I worked behind the scenes — shipping full products for agencies and developers who brought the clients. Themes, backends, mobile apps, design systems, trading bots. Real work, real stakes. My name was never on it. That was the deal, and I made the most of it.
Now I'm stepping out from behind the curtain. The Product Builder identity isn't a rebrand — it's finally being accurate about what I've always done: take an idea from concept to something real and live, across every layer of the stack.
