I'm an AI engineer who builds LLM-powered pipelines for sales, customer intelligence, and RevOps turning unstructured data like sales calls and conversations into structured, actionable business intelligence. I designed and built an AI-powered sales intelligence platform for a Tokyo-based ad-tech company, replacing a third-party call analysis tool that cost ¥400K+/month . The system processes sales call recordings through speech-to-text and a multi-stage Claude/AWS Bedrock pipeline to automatically produce: Rep coaching scores and specific, actionable feedback Objection detection and categorization Action item extraction with closed-loop tracking Call summaries and competitor intelligence Custom reporting tailored per team The system is now used daily across multiple departments, was onboarded by one team in under a week (a competing enterprise tool licensed elsewhere in the same company still hadn't launched after 3+ months), and has become an internal reference point for what a well-built AI pipeline looks like. What I bring: 20 years of engineering experience (Android, backend, full-stack) plus hands-on production LLM pipeline work not just prompt experimentation Real experience with the hard parts: speech-to-text accuracy, speaker diarization, multi-language handling (including Japanese), hallucination control, and cost optimization at scale Comfortable across the full stack: Next.js, Postgres, AWS (ECS, RDS, Bedrock, S3) If you have call recordings, conversations, or any unstructured data sitting unused and want it turned into something your sales or RevOps team can actually act on let's talk about what that pipeline would look like for your data and stack. Before the AI work, I spent several years building high-converting marketing funnels and CRM automation (GoHighLevel, webinar/VSL funnels, lead nurture systems) for info-product and coaching businesses the reviews and work history below reflect that chapter. That background is part of why I build AI systems with a clear eye on what actually drives business outcomes, not just what's technically possible.
