If your app is broken, behind schedule, or stuck with bugs you can't diagnose, I can help. I specialize in taking AI-built and half-finished apps the last mile: fixing, hardening, auditing, and shipping them to production. I've been building production software for 35+ years, including a decade as CTO and then Chief Product Officer at a fintech platform, where transaction correctness, data isolation, and security were non-negotiable. I still sit in that seat today as a fractional CTO for founders, guiding teams from idea through MVP launch. I've led architecture, run engineering teams, and shipped systems that had to hold up under real operational stakes. I build with AI tooling every day, including Claude and the Anthropic API, and I run my own business operations on an automated AI-agent pipeline I built. That's why my delivery timelines run ahead of standard estimates, and why I know exactly where AI-generated codebases skip guardrails and where they hold up. My recent production work centers on React, Next.js, TypeScript, Supabase (Postgres, Auth, RLS), Node.js, and Stripe. Recent engagements include pre-launch SaaS architecture audits, Supabase RLS and API security reviews, rescuing AI-generated MVPs (Lovable, v0, and similar) into production, and LLM feature integrations. Common engagements: - Pre-launch architecture and security audits, with a written findings and remediation report (Supabase RLS is a specialty) - Stabilizing and finishing AI-built or half-built MVPs - API integrations that fail, timeout, or return incorrect data - Auth, webhooks, and data sync issues - React rendering, state, and performance problems - Node.js / Express backend errors and crashes - LLM features: chat, scoring, extraction, and agent workflows I also work with Web3 systems when a project calls for it, including Ethereum and Solana smart contracts, token integrations, and wallet-based workflows. I'm available for short-term fixes, audits, and ongoing support. If you're not sure what you need yet, start with an audit: you'll get a written findings and remediation report you can act on with or without me.
