Sergii Nesterenko
A little about me
Hi, I’m Sergii.
My background spans web development, design, admin and sales, including work with customers and suppliers. I work with businesses and small teams, often on tasks that bring these areas together.
I like getting to know how people work, making sense of the details and finding a useful way to help. We can start with something small and see how it goes.
Outside work, I enjoy photography, motorcycles, 3D modelling and printing. I like making things and learning as I go.
