I am an active contributor to open-source projects, dedicating my free time to enhance collaboration and innovation. Here are some of my contributions:

• Created Arduino libraries:
  • DHT11 Arduino Library: A simple and efficient library for reading temperature and humidity data from the DHT11 sensor without dependencies.
  • SimpleUltrasonic Arduino Library: A simple and efficient library for calculating distance data from the HC-SR04 sensor without dependencies.

• Created tutorials:
  • How to install graphics.h in Ubuntu
  • Setting up WSL2 for C/C++/OpenGL Development - Step-by-step instructions

As a passionate gamer, I have gained valuable experience in server administration and automation. I have set up Minecraft and Rust servers to enjoy gaming sessions with my friends. Through these endeavors, I have acquired knowledge of automation using shell and batch scripts, as well as managing virtual machines and networks on platforms such as AWS, Google Cloud, and Azure. Here are the highlights:

• Developed an automated script for running a Java-based Minecraft server on Linux.
• Created a texture pack to prevent X-ray exploits and enhance anti-cheating measures.
• Operated a Minecraft server for my friends from 2019 to 2021, where I learned about Minecraft texture pack design and utilized Nvidia AI upscaling with CUDA.

• Founded and managed Rusty India, a Rust server community.
• Created a custom map of India using Rust Edit and World Creator.
• Gained expertise in network security, implementing Fail2Ban, Snort, Geo-IP based IP Filtering using IP Tables.
• Utilized bastion host for secure server connections.
• Acquired knowledge of TCP/UDP packet routing, ports, and game world development within game engines.
• Ran the server on Google Cloud.

To foster engagement and knowledge sharing, I established the VBDCSS IoT Club during my second year of university in 2022. This club aims to teach and inspire students about IoT and DIY projects. Additionally, I manage and created our department's GitHub organization, taking the lead in utilizing advanced GitHub features and fostering collaboration among students.
