Worked on scaling Tebak Gambar's architecture. Tebak Gambar is one of Indonesian Most Downloaded and Played games. It has more than 10 millions of downloads both on Apple App Store and Google Play Store. As Tebak Gambar started to introduce some features that requires server to handle requests from players, Tebak Gambar's server soon suffered from request overloads.I managed to scale Tebak Gambar's server and increases its efficiency. The server cost went down from more than hundreds of dollar each month to less than a hundred-dollar each month, while the server now can processes more than millions of request everyday compare to only thousands of requests before the scaling effort.
