I'm the senior technical person a founder brings in when the build is stalling, the automation half-works, or nobody can say whether what's been built will actually hold. Top Rated on Upwork, 475 jobs delivered, $700K+ earned, 100% Job Success, 10,000+ hours. I still write code every week. Most of my engagements start the same way: a paid diagnostic before anyone commits to a build. Current clients hired me to debug and plan a half-finished AI app before implementation, and to run a pilot before a full automation rollout. You find out what the work really takes before you spend the budget on it. Where I'm most useful: AI automation and agents — n8n, self-hosted and used daily. Workflow automation across email, documents and internal tools; AI agents wired into real business processes. Currently running accounting-process and estimating-workflow automations. Fractional CTO — architecture ownership, technical direction, and holding your contractors to a standard. I've led and reviewed engineering teams for years, so I know what a dev shop is doing when they tell you something is hard. Codebase rescue — inherited, half-built or vibe-coded projects. I find what's actually wrong before anyone writes a line of new code. Hands-on build — React, React Native, Next.js, Supabase, Cloudflare Workers and Pages, AWS. Web and mobile, shipped to production and kept up at load. Data at scale — 15,000+ scrapers and 70+ aggregation bots built and maintained, delivering 300K+ data points per minute. I work AI-augmented: Claude Code and Cursor daily, on real client repos. After 475 contracts the value isn't the tools — it's knowing when their output is wrong. How to start: Free 48-hour audit.
