About Work Projects

Hi there! I'm Jainil.
I at
UC Berkeley.

Hey! waving_hand

My name is Jainil, and I'm a senior at UC Berkeley majoring in computer science.

As a child, I would often find myself solving riddles and fiddling with the classic Windows 7 sliding puzzle. Although I parted ways with my antiquated PC in 2013, my love for puzzles remained intact. I sought programming as an outlet for myself, relishing the challenge of solving "algorithmic" puzzles (except with real impact now!).

On this website, I've attempted to catalogue some of the puzzles I've tinkered with and experience I've accrued.

This past summer, I helped rethink AWS IAM at Plaid. Presently, I'm exploring problems in robot grasping and manipulation at BAIR.

In my free time, I enjoy playing cricket, hitting the climbing gym with my friends, and geeking out over sports.

Secure File Sharing System

Go
close

I developed an end-to-end encrypted file management system in Go. The app featured secure support for user authentication, file storage and retrieval, and file sharing and revocation. My implementation ranked 1st in a class of 650 students.

Version Control System

Java, Git

Built an end-to-end secure application that allows users to store and share files (ranked 1st out of 650 students).

Version Control System

Java, Git
close

I built a miniaturized version control system in Java. The system leveraged file persistence and cryptographic hashing. I added support for remote functionality alongside core version control features (e.g. commit, checkout, merge).
