Build an AI-Powered B2B Lead Intelligence & Automation Platform

Hi, I'm looking for an experienced AI/full-stack developer to help design and build an internal lead generation automation platform for my company. Today, our process involves manually sourcing contacts from LinkedIn, Sales Navigator, Apollo, and ZoomInfo, verifying them through phone calls, identifying email patterns, performing QA checks, and delivering qualified leads to our Customer Success team. The objective is to automate as much of this workflow as possible using AI while maintaining high data quality. The platform should be able to: Source contacts based on campaign criteria Identify and enrich decision makers Discover and validate business email addresses Run automated QA against campaign parameters Flag exceptions for human review Generate delivery files and reports Integrate with APIs such as Apollo, ZoomInfo, LinkedIn (where applicable), and CRM platforms I'm looking for someone who has experience building AI-driven workflow automation, agentic AI systems, LLM applications, data enrichment platforms, and scalable SaaS products. Please share: Similar projects you've built Your recommended tech stack Your approach to solving this problem Your availability and estimated timeline If you've built products in sales intelligence, lead generation, CRM automation, or AI agents before, I'd love to hear from you. Thanks, Puneet
