Compass

Manually scrolling through LinkedIn job listings, evaluating fit, and applying one by one wastes hours every week. Most job seekers give up before finding the right match.

Built a Chrome extension backed by an AI pipeline. Jobs flow through multi-stage processing: scraping → filtering → AI scoring against resume → salary estimation from 4 independent sources → one-click apply with AI-generated cover letters.

1. LinkedIn's DOM changes constantly, so I built a resilient selector system with fallbacks
2. Rate limiting required session rotation and exponential backoff
3. Salary estimation needed cross-validation across LinkedIn data, Coresignal API, GPT-4o-mini estimation, and an algorithmic fallback
4. Multi-step Easy Apply forms with dynamic field detection and answer caching
