Background
Software, with a background in finance
I've worked at FactSet, and I've been a long-term investor for more than ten years.
Today I work independently, across several projects, in English and Bulgarian. I'm based in Sofia, Bulgaria, inside the EU.
Working together
How I work with founders
I join early-stage founders as their technical partner, for an hourly rate plus a small share of the company. I also take on business clients when the project is a good fit.
