Jobtoss is a Chrome extension I built solo on the Claude Agent SDK. It reads a job posting, parses my resume, writes the cover letter, fills the application, and submits — autonomously. The code is private. The product is live on the Chrome Web Store.
The problem
A serious applicant spends two to four hours on a single job application. Most of that work — tailoring, formatting, filling identical fields — is exactly what an LLM with browser access should absorb. Nothing on the market actually closed the loop.
Process
- 01
Mapped the application flow across the major ATS platforms — Greenhouse, Lever, Workday, Ashby — to find shared primitives
- 02
Designed the agent loop on the Claude Agent SDK: read posting, parse resume, decide fit, draft cover letter, fill, submit
- 03
Built the extension on Manifest V3 with a service worker, content scripts, and a popup configured to stream Claude responses
- 04
Wrote the resume parser to extract structured experience and the cover letter writer to mirror the candidate's voice
- 05
Shipped to the Chrome Web Store, started tracking sign-ups, and kept iterating on the agent loop

Solution
A production Chrome extension with a popup configurator, a background agent loop, and streaming output from Claude. Users set it up once, hit go on any job listing, and the agent handles the rest. The architecture is honest about what's automated and what isn't.
Results
Live on the Chrome Web Store. Early users report cutting application time from two hours to under ten minutes. Open to collaborators and investment conversations.
