AI Agent Developer | Claude Code & MCP | Private AI Automation

I build custom software that takes the busywork off your plate, in your business and in your busy life. AI agents and automation, built with Claude, Claude Code and MCP around the way you already work. The pattern I see most: hours lost to email, admin, follow-ups, invoices and chasing things across five different apps. I sit down with you, find the work that repeats, and build the tool that does it for you. Sometimes that's an AI assistant on WhatsApp that answers your customers. Sometimes it's a custom web app that pulls your CRM, inbox and documents into one place. Often it's a small team of AI agents that handle the routine and only come to you when a decision is needed. I run my own business this way. AI agents handle my finance, marketing and client admin, and nothing sends, spends or publishes without my approval. What I build for you is what I use every day. On Upwork I've built an AI operations system for a private family office, a custom AI agent setup for document compilation and a persistent browser-automation stack, and I've advised an advertising agency on AI. I also built and run NoraAI and VeoStudio.ai. Top Rated Plus, 100% Job Success, 50+ projects shipped, 18+ years building software. I build every system myself, so we work together directly, from the first call to the last deploy. When I quote you a time, I'm confident I can deliver it in that time. I'd love to jump on a call and talk about your project.
