PintOS Operating System

A fully functional single-coreoperating system in C for the x86 architecture. It supports multithreading, loading and running user programs, dynamic stack alloction, buffer cache and an inode-based FFS file system.

Secure File Sharing System

Fully secure end-to-end encrypted system for creating and sharing files through an insecure database

Build Your Own World

2D Random World Generating Game in Java

RookieDBMS

A lightweight, Java-based DBMS built throughout UC Berkeley’s CS 186 curriculum, implementing core systems concepts across projects 2–5—from B+ tree indexing and joins to concurrency control and ARIES-style crash recovery. It supports efficient query processing, ACID-compliant multi-transaction execution, and fast restart after failures.

Reliable TCP Socket

A Python‑based transport-layer socket built atop the POX network simulator to implement a TCP-like protocol (3‑way handshake, byte-stream transfer, FIN teardown, retransmission strategy with RTT/RTO estimation, and flow-control)

Pacman AI Agents

Developed and trained a suite of intelligent agents for playing Pac-Man, making use of search algorithms, probabilistic reasoning, adversarial planning, and reinforcement learning

Scheme Interpreter

A Python-based interpreter for a Scheme functional language, implementing a full read‑eval‑print loop and core language features (special forms, user-defined procedures, tokenization, and parsing).

RISC-V Classifier

A RISC‑V assembly-based MNIST classifier that ingests image and weight files, executes a fully-connected neural net (matrix multiply → ReLU → matrix multiply → argmax), and outputs digit predictions

Pipelined CPU in Logisim (Circuits)

Pipelined version of logic circuit of a 1 clock cycle CPU

Snek in C

Modified Snake Game written in C with optimized memory
