I review software and workflows built with AI, identify the highest-priority risks before customers depend on them, and lead or do the fix, priced separately. 20 years shipping, ex Head of Engineering for a 1M-user app, top 1% on Upwork. I do 2 kinds of work. 🛠 Production readiness for AI-built software. You built something with AI and it works. Before paying customers depend on it, someone needs to check the backups, what happens when 30 people hit it at once, how you ship a change without breaking it, and who you hire next. I review the architecture and hand back an ordered plan with effort estimates against each item, plus a hiring spec if you need one. 🤖 AI automation and AI agents. Custom agents for a specific business process, built on the Claude API, OpenAI, or open source models. Report pipelines, data extraction, content generation, competitive research, all running on a schedule with nobody watching them. I also set up and integrate Claude Code, Codex, OpenClaw and Hermes for teams adopting those tools. RECENT WORK 🎥 A contractor walkthrough video goes in, a priced estimate comes out 30 minutes later, unattended. 📊 A report pipeline that pulls from OneDrive, runs the analysis, and delivers the formatted result on a schedule. 🔎 Multi-source research agents that scrape, score and draft, then push the output to Telegram. 📱 Private Notes went from idea to the App Store in 21 days and runs its AI 100% on device. STACK Claude API, OpenAI API, Python, AWS Lambda, OpenClaw, Hermes, Cloudflare Workers, REST and webhook integrations. On the review side I work across Next.js, TypeScript, PostgreSQL, Supabase, Neon, Vercel and Stripe, covering backups and disaster recovery, concurrency and connection pooling, secrets, staging and CI. BACKGROUND I ran client engineering for an app with over 1M active users. We rewrote 2M+ lines from React Native to fully native and held a 99.9% crash-free rate through it. The company was acquired in 2025. As Chair of the AI Committee at a 60 person company, I took weekly time saved per person from 1 to 2 hours a week to more than 6, within 2 months. I put my first app on the App Store the week it opened in 2008 and have shipped 50+ since, including one that was #1 Top Grossing in 5 countries. Expert-Vetted by Upwork, the top 1%. 100% Job Success across 29 contracts and 1,295 hours. Tell me what you're building and I'll tell you what it needs.
