About this website
This website was originally created to experiment with (at the time) new web technologies to me like Next.js and TailwindCSS. Since then, it has become a personal portfolio site and host for various miscellaneous web tinkering.
The structure and function of this website was largely inspired by sheeptester.github.io. View the source code for this website on GitHub, or a directory of all pages here.
Jumpseat
2024
Jumpseat is a travel engine for college students that pairs flights with airport shuttles to find the optimal travel itinerary to and from Purdue, UIUC, and more.
Originally a student startup, a lightweight fork of Jumpseat is now hosted and maintained by me at jumpseat.kevin.fish.
Jumpseat is built using TypeScript, Tailwind CSS, and Next.js, and stores user preferences / breaks via Prisma + Postgres.
Photo host
2025
image-utils is a custom photo host built to address usability / cost issues with Microsoft OneDrive and other photo sites.
Along with a Next.js frontend, the repository contains several scripts to manage image conversion (HEIC -> WEBP with minimal color loss), optimization, and S3 uploading. The project supports grouping photos into albums, linking / embedding images, and more.
Scrape bot (Tom Scott)
2024-2025
scrape-bot, affectionately called Tom Scott, is the central system coordinating the attack/dev CI pipeline for the Purdue team @ MITRE eCTF 2025.
Tom consists of a Discord / Slack bot that
- tracks and summarizes the eCTF scoreboard into daily reports,
- integrates with the build CI to maintain the current build status and alert on build failures,
- listens on the Slack
#targetschannel to detect teams entering attack phase, - unzips and pushes new targets to the targets GitHub repository,
- distributes new targets to the build server / attack queueing system to run automated attacks (incl. dispatching the special "pesky neighbor" attack via Slack userbot),
- logs attack script output in Discord,
- and automatically submits any flags found to the CTFd backend.
See Tom Scott at the eCTF awards ceremony here!
CTFs
I participate in Capture the Flag (CTF) competitions as part of Purdue's CTF team b01lers! I typically solve web and misc challenges, and we generally rank ~7th in the US on CTFTime.
