Projects by Aditya Karad

Costco Index (2026)

I built Costco Index to compare everyday item prices across U.S. Costco warehouses. Costco sells a lot of essentials at low margins, so I want to see whether its prices can tell us anything about changes in household costs. The site has a map, price history, and a watchlist. About the project.

Instinct Relay (2026)

A local MCP tool that lets coding agents use Instinct's generous daily token budget for small coding tasks over WhatsApp. It returns diffs for review. GitHub.

/autoroute in Codex (2026)

I forked OpenAI's Codex CLI and integrated Jev to build /autoroute, an LLM router that picks a model and reasoning effort for each task from a model catalog. It aims to cut model costs and also suggests skills. I ran evals for both; the skill selector found the expected skill in 76 of 84 prompts. I put my fork on GitHub and wrote up how it works and what I tested.

EarlyApply (2025 + 2026)

EarlyApply uses browser automation and computer-use agents to make job hunting easier. It turns official company career pages into searchable job records, then puts them alongside hiring trends, metrics, bookmarks, notes, and application history.

I reached the Notion Hackathon finals with this project, which used Notion as its database and Notion Workers.

I planned to productize it, but onboarding each user cost too much in compute and tokens without a way to monetize it.

BusTub (2024)

For database systems coursework, Aditya implemented core components of CMU's disk-based BusTub database in C++17: a buffer pool manager, disk scheduler, extendible hash table, query execution engine, and concurrency control mechanisms.

ReadySetMenu (2024)

A fault-tolerant, scalable restaurant order-management system using RabbitMQ, MongoDB, and dynamic AWS EC2 provisioning to scale during demand surges. Source code.

Texera and Kubernetes (2024)

Work with Professor Chen Li on a control plane that deploys isolated Apache Texera instances with hardware limits in under five seconds using AWS EC2, EFS, and EBS. The project also ran Texera in an on-premises Kubernetes cluster for more than 150 concurrent users. Demo.
