Experience

Visibility Control Automation Dashboard

I wrote the application's back end in Go and some part in Python Flask using RPC (remote procedure call). The application provides control to various other machines and provides the visualization about the various metric of the system such as health, network, automation performance, and so on.

As a back-end developer, I was responsible for database design, exposing the RPC endpoints, writing Envoy and Nginx, and the System D configuration for the service.

Mixed Lyrics Search Engine

https://github.com/saurabhjn76/mixed-lyrics-search

I built a search engine that searches for a user song, robust against the small differences that occur, in the phonetic translation of non-English words in the Roman script of the song. I also created a RESTful API that can be used by Android applications to get data from the service.

Race the Car | Game

https://github.com/saurabhjn76/Race-the-car

I developed a strategic double-player board game in Python much like a shorter version of chess, where one needs to stay focused, anticipate the other player's moves, and cover all the tracks.

I used various mathematical concepts of coordinate geometry and graph theory and implemented the graphical interface using Pygame. The project was selected for NJACK Winter of Code hosted by IIT Patana.
