Project Name Image Description
Cognateful Image from my language learning app Interactive language-learning app that teaches you French using stories written in French, with translation exercises that are scored using large language model judgements.
NeRFs from Scratch A gif of a spinning lego Designed and implemented a NeRF (Neural Radiance Field) model in PyTorch based on the original NeRF paper. Successfully reconstructed a 3D scene of a rotating LEGO truck from a set of 2D views.
GSO: Software Optimization Tasks for Evaluating SWE-Agents An image of the GSO task generation pipeline Paper Accepted at NeurIPS 2025 (Datasets & Benchmarks Track): Coauthored Global Software Optimization (GSO), an LLM code optimization benchmark spanning 102 optimization problems and five programming languages.
PintOS (Operating Systems Class Project) An image of the PintOS operating system Built a transaction-safe Unix-like file system with hierarchical inode structure, resizable files, and rollback recovery. Developed an in-memory buffer cache with fine-grained locking for concurrent disk I/O. Implemented a POSIX-style threading subsystem with kernel-level synchronization primitives and priority scheduling to enable true parallel execution.
RISC-V CPU RISC-V CPU Datapath Built a full CPU in Logism that runs instructions in assembly language. Implemented two-stage pipelining to increase throughput. Prevent control hazards via pipeline flushing.
FactGrid Cuneiform Project FactGrid Cuneiform Project Develop machine learning model to segment and transcribe dataset of 1,068 annotated Cuneiform tablets using the YOLOv8 architecture.
The David Deutsch Dictionary The David Deutsch Lexicon Online database of quotes from science author and quantum physicist David Deutsch. Utilizes Google Sheets as a backend database to allow for seamless and near-real-time updates. Scraped quotes off the internet using Python3 and NLTK (Natural Language Tool Kit). Designed UI using Flask and HTML.

Bio

My name is Vijay Kethana, and I’m a computer science student at UC Berkeley. I’m working towards specializing in AI and machine learning. Outside of school, I enjoy cooking, hiking, and learning languages.
