Founder, Sell Bio

Writes here as Doni

LinkedIn

I'm a frontend engineer. Seven years building production web products across healthtech, telecom and SaaS — and I build Sell Bio on the side. Everything published on this blog is mine.

Where this comes from

At Hubtype I led the development of a visual editor for conversational flows used by enterprise clients — the same shape of problem Sell Bio solves, one category over. Before that I was CTO at a digital agency, leading a team of six across more than fifteen projects. Today I'm a frontend engineer at Claap. Sell Bio is part of the Lanzadera accelerator cohort.

Why I write this

There are 189 articles on this site across seven languages, and teaching is not new either: for six years I ran Doni Spot, publishing more than ninety web development tutorials. What's different here is that I also build the tool the guides describe. When one says a pattern works, it is because it was built, shipped and watched — not because it reads well.
