The challenge.

A B2B sales team had 70K target leads in their CRM with only names and company names — no job titles, emails, or context for personalized outreach. LinkedIn's aggressive anti-scraping measures and login walls made bulk extraction extremely difficult without account bans.

The approach.

01

Residential Proxy Rotation

Deployed a pool of 500+ residential proxies with per-request rotation and geo-targeting to distribute requests across IPs. Implemented automatic proxy health checks and ban detection with instant failover.

02

Session & Fingerprint Management

Created persistent browser sessions with unique fingerprints (viewport, timezone, language, WebGL hash) to avoid detection patterns. Rate-limited to 80-120 profiles per session before cycling.

03

Structured Data Extraction

Parsed profile pages for current title, company, employment history, education, skills endorsements, and mutual connections. Handled edge cases like private profiles, abbreviated names, and non-English layouts.

04

CRM Integration & Dedup

Built a direct API integration with the client's HubSpot instance. Matched extracted profiles to existing CRM contacts, enriched records in-place, and flagged duplicates for manual review.

Sample output.
