Senior Back-End Engineer

1/2015 – 12/2020

I worked as a freelancer in the blockchain, finance, health and telecommunication domains and had the opportunity to contribute to the success of some startups in their early days.

I helped to develop and architect the back-end tier for an up-and-coming risk management company and was later working as lead back-end at a robo advisor firm until its acquisition by a Fortune 500 company.

I also had a brief stint on the blockchain world where I devised an application to distribute utility tokens to the contributors in the ICO and also to investors.

Besides startups, I was also collaborating with more established companies working as a back-end developer in their teams.
