I have started two small businesses in 2020/2021:
- overpassage.com - A one-man consultancy for teaching/workshops (RL, ML, QC), R&D for hire and deep tech blogging for hire. On hold now, not taking any new customers.
- alphalerts.com - SMS/E-Mail/App alerts for financial events (currently focusing on US options), e.g. alerting when option greeks (or special ones such as Equity Put/Call Ratio) reach custom thresholds.
I am also a co-founder and the CTO at Aqarios GmbH, where we're building a quantum computing platform.
