"After my long career at Deloitte, I made the decision to join a dynamic company with an ambitious technology product. It has been one of the best decisions at a professional level. I joined Seedtag as Finance Controller, since then, I have not only worked a lot with a team where I feel totally comfortable to make decisions in the most agile way, but also in 1 year and a half I have faced challenges, in which Seedtag has trusted me to manage it and this has not only contributed to my knowledge but also to my professional development."
