Sander Spies
Independent
Sander Spies
Independent,
As a developer always focusing on the reader of the code. Fell in love with React in 2013 because of the simplification it brought to state management. Regrets asking for Flux. Big fan of CSS-in-JS and currently lost in OCaml. Strongly believes in the importance of moving developers to Reason as it removes a lot of the burdens that JavaScript developers face daily. Can be blamed for several things in Reason like JSX. Reason fan since day one.
