An Insider's view of Wish

How has your career grown since starting at the company?

My goal coming out of university was to learn how to scale the infrastructure of a growing company. Larger tech companies have mostly solved these scalability problems and Wish gave me the opportunity to solve tough problems hands on. Wish is now handling 100x the traffic since I joined and I'm still learning new things everyday.
