Building Longlist: a job application tracker

I was tracking job applications in a spreadsheet and kept losing the thread. Which of these did I already apply to? What closes this week? Did that company come back to me, or am I thinking of a different one?

This was my first attempt as using agenting engineering (claude code + claude design) to build an application.

I built Longlist. Every role goes in once and moves through six stages: interested, applied, online assessment, interview, offer, rejected. The dashboard shows a donut chart of where everything sits, plus a table you can search, filter and sort.
