Hello There!

I am Ben Paul Varghese, a final year CSE student at International Institute of Information Technology, Hyderabad.

About Me

I developed an interest in Computer Science in middle school, and since then, have taken multiple courses (either from school or online) to learn more about the subject. These are some of the languages, APIs, and libraries I have experience in, and have used for all the projects and similar work I have done.

  • C
  • C++
  • HTML, CSS, JavaScript
  • MERN stack
  • OpenGL, WebGL
  • ThreeJS
  • Python
  • Bash Scripting
  • SQL

Projects

Shell

Created a Linux shell from scratch using C as part of the Operating Systems & Networks course at IIIT-H. Implemented most common commands like cd, ls, pwd, echo, etc., while also handling support for foreground and background processes, including signals and interrupts.

xv6 OS

Tweaked the xv6 Operating System as part of the Operating Systems & Networks course at IIIT-H. Added two new system calls - strace and set_priority.
  • strace traces the system calls made by a command.
  • set_priority changes the priority level of a process to the value entered by the user.
Also implemented two new schedulers (FCFS and PBS), in addition to the default round-robin scheduler.
  • FCFS (First Come First Served) - The process which comes first is run first.
  • PBS (Priority Based Scheduler) - The process with the highest priority is run first.

Nautica

Created a 3D game using WebGL and ThreeJS as part of the Computer Graphics course at IIIT-H. Game involves moving across the ocean as a ship, while collecting treasure and destroying enemy ships. Destroying enemy ships causes a greater number of enemies to spawn. The game lasts as long as the user has health remaining.

Canteen Portal Website

Made a canteen portal website as part of the Design and Analysis of Software Systems course at IIIT-H. The website has the following features -
  • Create/Edit profile for both buyer and vendor
  • Login/Registration
  • Vendors can add food items to their dashboard
  • Buyers can see food items available from every vendor
  • Buyers can search (fuzzy search) and filter according to their wish
  • Buyers can update their wallet balance
Also packaged and deployed the website using Docker.

Bitcoin Simulator

Designed a bitcoin simulator as part of the Data Structures & Algorithms course at IIIT-H (group project of 5 people). The simulator has support for a large number of users and transactions. Each transaction is stored in a block structure and the entire program will have multiple such blocks - forming a blockchain. Each block also has a hash value for verification and security purposes. The simulator has several functions, some of which are -
  • Adding users
  • Conducting a transaction
  • Hash function, to generate a hash value for each block
I was heavily involved in writing the code for the simulator, and also completely handled the design of test cases.

Algorithms Website

Created a website as a guide for beginners to algorithms as part of the Algorithms Analysis & Design course at IIIT-H. The website had a simple UI, along with easy to understand explanations of several famous algorithms under Divide & Conquer, Greedy, and Dynamic Programming.

Parliament Database

Implemented a database based on the Indian Parliament System using MySQL and Python as part of the Data and Applications course at IIIT-H (group project of 3 people). The database stored some of the members of the lower and upper houses of the country, as well as the states councils. Also designed a Python program to query the database for selection and updation. I was mainly involved with the MySQL part of the project, which involved designing the database itself and adding the data.

Card Game

Simulated a card game called 99 using C++ as a personal project during my free time. In this game, the user plays against the computer, and the one who loses their cards the fastest is the winner. I created the code such that the computer always makes the best possible choice at every step.
