I've been writing production code for 7 years — Rails, React, Stripe, data pipelines — before AI tools existed. That foundation is what makes me effective with them now. I know where agents go wrong because I've debugged those problems by hand. Two things I do: 1. Build AI agents for businesses. Workflow automation, LLM-powered pipelines, document processing, internal tools that replace manual work. I use the Anthropic and OpenAI APIs, connect them to your existing systems, and ship working agents — not demos. 2. Ship SaaS faster with agentic development. I run Claude Code and Codex on real Rails apps daily. Agents handle the boilerplate; I own the architecture, Stripe billing, auth flows, and the parts where AI output can't be trusted blindly. Recent work: AQVC (fintech platform + data pipelines), Groundwork (SaaS onboarding + admin), MarbleFlows (academy platform + embeds). Looking for companies serious about AI — either building AI-powered products or transforming internal operations with agents.
