Md Masta Hasenur R.

GTM Engineer and Outbound Growth Specialist. I build low-cost, AI-powered outbound systems that generate qualified meetings through Claude code, Cold Email, LinkedIn, SMS, AI calling system and CRM automation. Over the past 8+ years, I’ve helped 300+ businesses generate leads, book qualified appointments, optimize sales processes, and grow revenue. I’ve gone from manually running outbound campaigns to building the complete GTM infrastructure behind them, and I can handle both strategy and hands-on execution depending on what you need. A big part of my work today is GTM engineering with Clay. I build enrichment, waterfall data, lead-scoring, ICP segmentation, buying-signal, and AI personalization workflows that turn raw prospect data into prioritized lists your sales team can actually use. I connect Clay with Apollo, Smartlead, Instantly, HeyReach, HubSpot, Airtable, Sales Navigator, Zapier, Make, n8n, and APIs, while using Claygent, Claude, and ChatGPT for scalable 1-to-1 personalization. My approach is increasingly signal and intent-driven. Hiring activity, job changes, funding, website visitors, technology usage, competitor engagement, LinkedIn activity, firmographic fit, and reply behavior can all indicate when there’s a real reason to reach out. I use those signals to trigger personalized LinkedIn, cold email, WhatsApp/SMS, AI calling, and CRM workflows. What I deliver: • Clay enrichment, waterfall data, lead scoring, and AI workflows • Signal and intent-based prospecting aligned with your ICP • Cold email infrastructure: domains, mailboxes, SPF/DKIM/DMARC, warmup, and deliverability • Smartlead, Instantly, Lemlist, and ReachInbox campaign setup • LinkedIn outbound with Sales Navigator, HeyReach, Expandi, Dripify, and LGM • High-volume LinkedIn prospecting, InMail, and 1st-degree outreach • Competitor-follower and engagement-based targeting • 1-to-1 AI personalization with Claygent, Claude, and ChatGPT • CRM automation, lead nurturing, pipeline management, and RevOps • Zapier, Make, n8n, Unipile, webhook, and API integrations • WhatsApp/SMS automation, AI outbound calling, and reply agents • Lead generation, appointment setting, reply management, and CRM hygiene • Reporting on replies, qualified meetings, pipeline, and campaign performance Who I work with: I’ve supported 300+ businesses across B2B SaaS, AI, recruitment and staffing, healthcare, FinTech, agencies, IT services, consultants, professional services, e-commerce, and other B2B markets that need predictable conversations with the right decision-makers.
