Publish-Subscribe System using Broker Architecture                                                                          January 2023 to March 2023

Santa Clara, CA               

• Designed and implemented a scalable distributed publish-subscribe system with publishers, brokers, and subscribers. Brokers are built on a peer-to-peer Chord architecture, ensuring efficient data distribution and network scalability. Subscribers are integrated with spanning trees, enhancing system scalability and minimizing communication overhead.
• Fault tolerance is enhanced by implementing a gossip protocol to detect and report system failures, and a bully algorithm is used to achieve leader election, significantly improving system robustness.
• The project is developed using Java RMI and deployed with Docker, enabling scalable and containerized deployment.

Simulation of Customized Virtual Memory and File System                                                                 January 2023 to March 2023

Santa Clara, CA

• Developed a virtual memory system that mimics a one-level Page Table and Translate Lookaside Buffer (TLB), providing an accurate representation of how an OS manages memory.
• Simulated an indexed-allocation file system, incorporating principles from linked allocation and utilizing i-nodes, replicating common command-line operations similar to those found in modern file systems like Linux.
• The project, completed using C, effectively demonstrates how an OS provides essential abstractions to processes and users, enhancing understanding of fundamental operating system concepts.
