Projects

C/C++

Mithril is a distributed search engine built from scratch by a team of 7, with fault-tolerant crawling, PageRank-style ranking, and web-scale indexing over a 100M-document corpus.
Led indexing, cloud infra, and perf: block-based indexing, tiered merges, VByte compression, mmap dictionaries, selective positional indexes, 75K docs/min ingest, and sub-500ms queries. [link], [paper, wip], ['25]

Aslam is a high-performance LSM store with lock-free memtables, parallel compaction, MVCC transactions and optimized block caching. Consistently hits 1K+ QPS on mixed workloads. [gh], [wip]

Pulsar is a cross-platform, modular 2D game engine with multi-threaded physics sim, fast parallel ECS, Lua middleware, data-oriented design and a Unity-esque interface. [gh], ['24]

DrawBot is a drawing robot that brings touch-drawn paths to life. Built the full stack - from display UI to differential-drive control, path planning and wireless comms. Runs on two STM32s with sensor fusion, PID control and a neat pen servo setup. [gh], ['24]

Quadcopter Autopilot is a ROS2/C++ flight stack for autonomous navigation and landing. Built with aero/mech/CE teammates; I owned the controls path: SE(3) EKF over IMU, camera, AprilTag, and ToF, plus the landing state machine. ['24]

foobar is a modern vim-like editor built from scratch with a gap buffer for O(1) insertions and custom terminal renderer. Implements raw mode handling, ANSI escape sequences and efficient screen updates with modern C++. [gh], ['24]

rtc implements path tracing with BVH acceleration, textures, volumetrics and instanced transforms. Building full pipeline from ray-object intersections to material sampling and multi-threaded rendering. Based on Shirley's RTiOW+RTiNW. [gh], ['24]

mallot is a thread-safe memory allocator with segregated free lists, mmap-based pools, block coalescing. Implements full malloc/free/realloc interface with proper alignment + frag handling. [gh], ['24]

mOSy is an xv6-like operating system with user-space thread library featuring FIFO scheduler and context switching for 50+ concurrent threads. Implemented demand paging, copy-on-write fork, file-backed mappings with unified buffer cache and LRU eviction policies. ['23]

Systems projects including RISC-V assembler/simulator/linker, pipeline and cache simulators, SQL-like relational database, real-time trading exchange, and other performance-critical applications in modern C++. ['22, '23]

Go

kvstore is a linearizable distributed KV database with sharded replicas, Paxos consensus, and dynamic reconfiguration. Implements fault-tolerant replica groups with cross-shard transactions, seamless data migration, and a robust config service for automatic shard rebalancing. Maintains 99% availability under network partitions and node failures. ['24]

mClasses is a distributed search engine with lock-free concurrent indexing, custom vector DB, and an optimized query compiler for course relationship graphs. Consistently hits sub-2ms p99 latency across 80K+ nodes. [link], ['24]

gorbis is a spatial data engine with R-tree indexing, KNN search and clustering support. Features fast bulk loading, bbox queries and a MapLibre viz frontend. Inspired by Uber's H3 libs. [wip], ['24]

vasco is the UMich campus locations, buildings database and API. Feeder to an ongoing project with maps and scheduling. [gh], ['22]

Python

mdrone-vision is the AprilTag vision component of the quadcopter project: camera pipeline, tag detection, pose estimation, and UART comms to the flight controller. [gh], ['24]

xmarks-to-notion is a fast bookmarks migration tool with browser automation + Notion sync. Has local caching, retries, rate limiting and clean exports. Weekend hack to save my X bookmarks. [gh], ['24]

Robot-learning projects around planning and control under uncertainty: Bayesian optimization for robust MPC policy search, VAE latent dynamics from raw images, GP models for uncertain dynamics, and policy-gradient RL implementations. ['23]

A fully-homomorphic encryption scheme based on the hardness of the RLWE problem with support for ciphertext addition and multiplication through relinearization and modulus switching. Crypto class final project. ['23]

An occupancy based risk-aware path planner for delivery drones built in six hours for a stealth startup's virtual onsite interview. Used RRT* with a custom cost function and a 3D occupancy grid. ['23]

BruhBot ecosystem included tooling for our online classes during Covid built with discord.py, a memeAPI, media backup workers, smart class note taking, reminder tracking, yearbook/zoom automation etc. ['21]

Phoenix is a real-time aerial wildfire tracking and forecast system. Wrote PCA, random forest, CNNs and sequence models from scratch. Selected as a National Winner for NASA SpaceApps ['20]

college-app-cli is an interactive terminal app for school counselors to track student college applications and manage application materials. Developed as my final grade 12 CS project. [gh], ['20]

matrix-processor is a Python lib for matrix ops written from scratch when learning linear algebra. Made math classes less painful. ['20], [gh]

MOCP discord rich presence lib for Unix music players. [gh], ['20]

cool math, art and code including a maze generator and solver, mitosis simulator, 3D terrain generators, Menger sponge, fractals, space invaders, hunt the wumpus, hangman, minesweeper etc. [gh], ['19, '20]

Math

Experimental math notes/papers from Math 389, written while learning how mathematical questions become models, computations, conjectures, and proofs. One explored discrete dynamical systems; another was a random matrix theory primer backed by numerical experiments. ['25]

Discrete differential geometry project through Math DRP, studying fast geodesic distance computation on triangle meshes via the heat method and discrete exterior calculus. ['25]
