Jobber

Opportunity-intelligence MVP - evidence ledger for job search, not a generic AI matcher

Jobber is an opportunity-intelligence MVP for developers and freelancers. It pulls live listings via Treg (RemoteOK, We Work Remotely, LinkedIn, Indeed), rejects mismatches with deterministic filters + dedupe, asks TypeSafe Jev 7 narrow typed questions (5 Scores + 2 Nouls), and calculates an inspectable 0-100 ranking with confidence lanes (HIGH/REVIEW/LOW). Includes cost-ledgered runs, company enrichment, and a full Next.js + FastAPI + Supabase stack. Features: - Live multi-source job search with budget-capped Treg calls + ExternalCall ledger - Deterministic normalize/dedupe/prefilter before any AI spend - Python-owned composite scoring (30/25/20/15/10 weights) with stored evidence - Costs dashboard, run logs, profile JSON import, Settings without .env edits

Applyer Automated Job Application

Watches remote job boards around the clock, scores new listings against my resume, and drafts tailored applications for strong fits within minutes of posting.

Applyer monitors remote job boards around the clock, scores new listings against my resume and preferences, and drafts tailored application messages for each match — so strong fits get a quality application within minutes of posting instead of hours of manual searching. A scheduled watcher polls listings every 15 minutes, deduplicates against known jobs, and pushes only top-scoring fresh matches to Discord with direct links. A local-rules matching engine scores each listing on skill overlap, salary normalization, recency, and employment type, with keyword allowlists and title blacklists to filter noise. One-click AI drafts are built from the full job description plus resume and profile context, with per-job style and length options and editable output. An async pipeline runner streams live progress and logs to the dashboard for every background task.

Polls every 15 min · strong fits applied within minutes, not hours
