Emmisary

Hi there!

I'm Amit Grinson, currently working as a Data Scientist at Meta.

I'm a Sociology MA graduate and a self-taught coder who loves to explore new data sets, uncover hidden insights and communicate them in an accessible way for others to take action or enjoy the read. I also have my own website where I infrequently blog about data analysis & visualization, peak my statistical curiosity or dive into random challenges I faced at work:

www.amitgrinson.com

Additionally, I have a pet project (in Hebrew!) where I share SQL challenges I encountered at work. I anonymize the data and challenge and provide the opportunity for you to try it yourself. Great for people wanting to upscale their SQL skills. There's also recorded solutions and the ability to signup for an infrequent newsletter; Give it a try (and let me know!) here:

sql.amitgrinson.com

Though you're reading this on LinkedIn you can also find me on Twitter (@Amit_Levinson) sharing miscellaneous tweets about data, SQL, R, Python or participating in various data visualization projects.

Bonus:
My MA thesis focused on issues of trust and privacy in the Israeli online cannabis market. In it I discuss users' negotiation of privacy and more on the relationship between disclosing personal information and trusting someone in an unregulated illegal market (Survey analysis with R).

Let's connect!
