Software Developer at Hulu

Jest is my go-to tool for building application tests. I've now moved two large teams off of other tools like Mocha and Proxyquire into Jest, and have created test suites for hundreds of components.

Maurizio Carboni, Jest dev and freelancerHire Now
Freelance Jest developer in Covent Garden, United Kingdom

Full-Stack JavaScript Developer

I am an experienced Full Stack Developer, during the decade of my career, I saw the technology change at incredible speed, making me learn a new stack every year. I started working during the time when iframe and tables were "cool", and PHP was "the language of the future".

During that time, not only my choice of database transitioned from MySQL (major choice in PHP) to MongoDB and finally to Postgres, redis and Mongo (choosing the right one for the right project), but I also learned that a successful website doesn't use simple queries, but also need that the database needs to execute some code on its side (triggers, functions, ...). I als...
