Written by an actual human. Ironic, since building with AI is my whole job, but every word here is mine, and so is every message you'll get. If a reply ever reads like ChatGPT wrote it, fire me. Most people who find me are holding an app that looks finished and isn't. Built in Lovable or Bolt over a weekend, demoed well, and now it's supposed to take real money from real users, and nobody knows whether it will hold. Or a contractor went quiet in week three and took the repo knowledge with them. That's the job. I read code I didn't write, work out what's solid and what only appeared to work, and get it to production properly. WHAT USUALLY TURNS UP API keys in the client bundle. Auth where any logged-in user can read another tenant's data. Stripe webhooks with no idempotency, so a retry double-charges. RLS policies that read correctly and don't actually isolate anything. No tested backup. Demo screens propped up by an empty backend. None of it shows up in a demo. All of it shows up in production. START WITH AN AUDIT. $400, 2 days. You give me repo access. You get a written report: every finding with file and line reference, severity, reproduction steps, and what it costs to fix. Auth and tenant isolation, exposed secrets, payment flow integrity, RLS correctness, behaviour under load. The report is yours whether or not you hire me for the fixes. You can hand it to any developer. Already have a developer and want a second opinion before launch? I do the review-and-verify side on its own. The person doing the work shouldn't be the person saying it passed. THEN, IF YOU WANT IT FIXED I keep what works, rebuild what doesn't, and hand the system back properly. Repo in your GitHub org, secrets rotated, staging and production separated, deploys you can roll back, and documentation good enough that the next developer doesn't need me. RECENT WORK Trimi. Lovable to Claude Code migration in two hours. Organic traffic 250k to 500k monthly after the migration and SEO push. Founders now ship updates without me. That was the point. Milpath. AI SaaS built with Claude Code and Codex, $5k MRR in 90 days. claudemarket.ai. My own AI directory, 60,000+ monthly visitors from technical SEO. Helpie AI. 1,000+ monthly active users. O-ts. 2x conversion rate after rebuild. ALSO MVP builds from scratch, idea to live product taking payments. AI apps and agents: Claude API, OpenAI API, RAG, chatbots. Migrations off Lovable, Bolt.new, Replit, Base44 and v0. Supabase auth, RLS, edge functions, Postgres schema design. Stripe checkout, webhooks, subscriptions. Claude Code and CLAUDE.md setup so your team can build AI-native without me. Blocked on a security review or an enterprise questionnaire? I do production hardening with a written control summary you can hand to whoever is asking. Stack: Lovable, Claude Code, OpenAI Codex, Base44, Replit, Bolt.new, Supabase, React, Next.js, TypeScript, Vercel, Stripe, n8n, OpenClaw. THE GUARANTEE Free scoping call before you spend anything. We map features, flows, milestones and price. Not a fit, you keep the plan. Working prototype in 3 weeks, real functionality on a live database, no mockups. Unlimited revisions within scope. WAYS TO WORK Audit, $400 fixed. Review and sign-off only, if you have a developer already. Fixed-price build or rescue, typically $2,500 to $15,000. Fractional developer, 10 to 30 hrs/week. Retainer from $650/month. You own the code either way. WHY THE SPEED IS REAL I was a software engineer at brainpool.ai, a London AI consultancy, building production LLM systems with LangChain, RAG pipelines and the Claude and OpenAI APIs before going freelance. That's the part that matters here. I can read the code, not just prompt it. When something breaks I debug it, rather than re-prompting until the error goes away and three new ones appear underneath. Claude Code, Lovable, Codex and Supabase are my daily tools, and after 50+ shipped projects I know where they fall over. Which generated auth patterns leak data, which edge functions time out under load, which screens are propped up by nothing. Knowing the failure points is what makes moving fast safe. WHAT CLIENTS SAY "Every technical finding, missing security headers, robots.txt, llms.txt, structured data, was specific, accurate and independently verified." SaaS founder, product audit. "Gets the job done without all the problems of working with the discount freelancers we all know about." Figma to Lovable build. Both from my verified reviews below. ABOUT ME I'm Zac. One developer in London, no account managers, no handoffs. I teach this stack to 3,000+ developers on YouTube and in a paid community. I keep the project load small, so if I'm at capacity I'll say so. No Shopify stores, and if you want pixel-perfect Figma work I'm the wrong hire Daily overlap with US Eastern. Hit Invite to Job and tell me what's broken. Fixed-price proposal within 24 hours
