Asif J.
B2B Lead Generation & List Building | Web Research | Python Developer
Top Rated Plus on Upwork with 18,000+ hours, 365+ completed jobs, and a 4.9-star rating across 287 reviews — I build accurate, sales-ready B2B prospect lists so your outreach starts with the right people, not guesswork. I help sales teams, agencies, and founders build and enrich prospect databases matched to their exact ICP: industry, company size, location, seniority, tech stack, revenue, or funding stage. Every list is manually verified, not just scraped — so your team isn't wasting time on bounced emails or wrong titles. Core services: ✓ B2B lead generation & targeted prospect lists ✓ LinkedIn Sales Navigator & Apollo research ✓ Decision-maker identification & contact verification ✓ Data enrichment, CRM cleanup & database building ✓ Python-based web data extraction for large-scale. ✓ Market & company research I work in Apollo, Sales Navigator, ZoomInfo, and Hunter for sourcing and verification, and use Python when a job needs custom scraping or automation beyond what off-the-shelf tools can do. Recent work has included building lists from 100 to 10,000+ verified contacts for industry/niche you work in most, delivered as clean, CRM-ready spreadsheets with 100% accuracy on email verification. Tell me your target industry, titles, and location, and I'll scope a sample list so you can see the quality before committing to the full project.
