01 · FEATURED PROJECT

Job Tracker

A Chrome extension I built for my own UK job search. It saves every application, scores how well each ad fits my skills, and keeps the whole pipeline in one dashboard, synced two ways with my own Google Sheet.

UK job boards captured automatically

TRY IT · THE FIT SCORE, LIVE

Would you apply to this one?

A sample ad, Junior IT Support Analyst. Set your level for each tool it mentions and watch the score move. Same rules as the extension: tools under Requirements weigh 1.5×, desirable ones 0.5×.

How it works

Everything runs locally in plain JavaScript: a dictionary of ~100 tools with regular expressions, an ad parser and a points-based score. No model, no network calls for scoring.

12 statuses from Applied to Offer accepted, a weekly chart, response rate per board, and follow-ups due.

DRAFTS FOLLOW-UPS

Email, a LinkedIn note under 200 characters, or a phone script, tailored to agency or direct ads.

A BUG A TEST CAUGHT

Sync first compared timestamps; a unit test showed two writes in one millisecond looked already synced. It now uses revision numbers.
