AI Agent Developer | Voice AI, Neo4j RAG, Document AI, Full-Stack Apps

I’ve delivered work for brands like Uber, McDonald’s, Airwick and Reckitt, and helped several clients launch products used by 1M+ users. I build AI agents, voice agents and document automation for teams buried in paperwork. One system I built now processes 1.5M documents a month and cut a two-week job to under three minutes. Some results I’ve helped clients achieve include: - Automated 1.5M documents a month for an HR software platform, cutting processing time from two weeks to under three minutes - Scaled an audio streaming app to 30,000+ daily listeners in its first two months - Raised operational efficiency by 80% with tools that coordinate 1,000+ volunteers across 1,000+ sites If you’re here, you probably want systems that just work... and keep working as you scale. Maybe you've worked with freelancers before who left you with buggy code, constant delays, or tools that looked great but didn't solve the real problem. What you actually need is a partner you can trust to own the project and deliver a solution that just works, no excuses. 👉 I’m JD, an AI automation-focused full-stack developer and Neo4j Certified Professional with 8+ years of experience building user-focused systems and applications. My work has contributed to products serving over 1 million users, achieved by balancing technical quality with real business impact. Today, I specialize in building systems that generate leads, close deals, and scale businesses, mostly using new AI models like Claude and GPT. What I build: - AI agents that read contracts, invoices and reports, and answer questions about them - Voice agents that handle phone calls and customer conversations - Knowledge graphs and GraphRAG search on Neo4j, so every answer comes with its source - Full-stack web apps (Next.js, Supabase) that put the AI in front of your team I start every project with a short scoping session to find where automation will save you the most time and money.
