- Very excited to share that I've started as a Software Engineer at Snowflake! 🥳 I’m also wrapping up my PhD: this week I’m at VLDB in London to present the last demo paper from my time as PhD student, and on September 17 I’ll defend my PhD in Amsterdam. Really looking forward to this next chapter!
