I used Claude Code to find scientific seminars hosted by colleges and universities across the US and collate them into a single, searchable list. Researchers can use it to find talks that match their interests near them. The site, seminarsearch.org, runs mostly on free-tier SaaS services, costs me $5 per month to operate, and currently supports a few thousand users. The same pattern could be adapted to collate all 5K runs in the US, tennis matches, craft shows, quilting bees, or any other type of event that interests you. I started by explaining to Claude what I wanted to build. We then spent a few hours exploring where and how to identify seminar calendars at universities across the US, which was arguably the hardest part. We developed a pluggable framework with scraping plugins for the common CMSs used by universities, along with iCal parsers, HTML parsers, and JavaScript interpreters to handle the complexity of normalizing content from hundreds of departmental websites. Once we had the seminar-scraping infrastructure, we built a database schema in Supabase and simple APIs to create, read, update, and delete records. The APIs are written in Python and hosted on Railway for $5 per month. We used Vercel to deploy a simple React-based frontend for presenting the data. Now I can ask Claude to implement a feature or add a new university to the list of sources. It figures out where the data is hosted, creates entries for the university and its departments, finds their seminar feeds, collects the seminar data, puts it into the database, and runs GitHub Actions to send alerts to registered users. The scraping job runs once a week to collect new data, and it also runs through GitHub Actions. I wrote zero code during this process and have never even looked at the code. I only had to paste a few error messages from Railway into Claude so it could debug them, and there were only a few errors. Since building seminarsearch.org, I have cloned the infrastructure and codebase and modified it to build a site that collects road bike rides and group mountain bike rides across the country. The system is highly extensible to new areas of interest and is useful when traveling or living in a large metropolitan area where it is difficult to keep track of all the opportunities available for your interests. Step-by-step: 1. I explained to Claude Code that I wanted to build a searchable directory of scientific seminars hosted by colleges and universities across the US. 2. We explored where and how to identify university seminar calendars, focusing on the challenge of finding sources across many institutions. 3. We built a pluggable scraping framework with plugins for common university CMSs, plus iCal parsers, HTML parsers, and JavaScript interpreters. 4. We created a Supabase database schema and simple Python APIs for creating, reading, updating, and deleting seminar records. 5. We hosted the APIs on Railway for $5 per month and deployed a React-based frontend on Vercel. 6. We configured Claude to add universities and implement features by finding source locations, creating university and department records, locating seminar feeds, collecting seminar data, and adding it to the database. 7. We used GitHub Actions to run the weekly scraping job and send alerts to registered users. 8. When Railway returned errors, I pasted a few error messages into Claude so it could debug them. 9. I cloned and modified the infrastructure and codebase to create additional sites for road bike rides and group mountain bike rides across the country.
