Luca is an eccentric programmer who discovered the art of writing code during his mechanical engineering PhD. For this reason he ended up not doing any of the experiments he was assigned and published mostly applied math papers. After a short adventure doing data science for a sport modeling company he now works as an Investment Engineer at Bridgewater Associates. He developed and maintains three shared libraries that are the core domain and DSL of the firm’s portfolio generation logic. He is known to his colleagues for having to take a walk in the park outside the office every time there is a “divergent implicit expansion”.
