You built something real with AI tools. We finish the hard last stretch: security, payments, deployment, legal and launch. That way you keep your momentum and ship something you can stand behind.
Book an inspectionFrom inspection to a clear, prioritised launch plan.
AI tools are brilliant at getting you to a working demo. Getting to something you can charge for, trust with customer data and leave running overnight is a different job. That's the job we do.
"It works on my laptop, but I'm scared to put real users on it."
Security & hosting"Every fix the AI makes breaks something else."
Code health"I need payments, a privacy policy and a real domain by next month."
Launch basics"My hosting bill just tripled and I don't know why."
Costs & performanceFixed scopes and fixed prices, so you always know what you're getting. We build on what you've made rather than starting over, and you own everything.
See packagesWe review your code, hosting and setup, then give you a prioritised punch list in plain English.
We fix what matters and add the missing pieces: auth, payments, legal and monitoring.
We take it live on your domain, with handover docs and a recorded walkthrough.
An optional monthly retainer for new features, fixes and health checks.
Most clients start with an Inspection. If you continue to Final Coat within 30 days, the Inspection fee is credited. Final quotes are always confirmed in writing before work begins.

Founders and operators who built something themselves and needed help over the line.
“We built our core MVP using Cursor and v0 in under two weeks. It looked great, but under the hood, the security was non-existent and the API calls were an unmaintainable disaster. The team at finalcoat.dev came in, refactored our backend, secured our endpoints, and polished our responsive UI. They turned our vibe-coded prototype into a rock-solid, production-ready product that passed our first enterprise security audit.”
They solved the ‘last mile’ problem we couldn’t figure out.
“Getting to 80% with AI tools was shockingly fast, but that final 20%—fixing weird UI glitches, optimizing database queries, and setting up proper CI/CD—nearly stalled our launch completely. finalcoat.dev took our codebase, cleaned up the AI bloat, and added the exact engineering polish we needed to actually go to market with confidence.”
It’s like having a team of senior staff engineers on retainer for your AI build.
“As a non-technical founder, vibe-coding got my product off the ground, but I knew I couldn’t launch to paying customers with AI-generated spaghetti code. finalcoat.dev didn’t just fix the bugs; they gave us a modular, clean codebase that our newly hired developers could actually understand and build on.”
We kept seeing smart people build genuinely useful software with AI tools, then stall just short of launch. finalcoat.dev is founder-led and based in Sydney, NSW. James works with a small network of trusted independent specialists, bringing in the right people for each project. We all build with the same tools you do. We meet you where you are, explain things plainly, and leave you more capable than we found you.
James is an engineering veteran who makes sure AI-generated products don't crumple under real-world pressure. After years as a backend architect, he founded finalcoat.dev to bridge the gap between “it works on my machine” and “it works for 100,000 active users.”
The final 20%The architecture auditor. He swaps brittle, AI-scaffolded API loops for high-performance, containerised, scale-ready infrastructure.
Elena protects businesses from the invisible traps of AI-written code. Grounded in cybersecurity and DevOps, she specialises in finding the vulnerabilities AI tools leave behind, like unvalidated inputs and exposed endpoints.
The final 20%She hardens the app with proper auth, rate limiting, CI/CD pipelines and data encryption, so products are safe to launch and compliant with industry standards.
Chloe brings the finish to the user experience. AI-built interfaces can look functional but often fail the delight-and-logic test. Chloe combines design-system expertise with behavioural intuition to turn generic AI-generated UI into a premium, bespoke journey.
The final 20%She inspects the final UX: fixing inconsistent spacing, messy button states and broken responsive views, and adding the micro-interactions that make a product feel premium.
Daniel gets a kick out of untangling digital spaghetti. With extensive frontend and backend experience, he specialises in finding redundant, non-semantic or AI-bloated code and making the codebase genuinely maintainable.
The final 20%He prunes hidden technical debt, fixes performance bottlenecks, writes robust unit tests, and refactors AI output into clean, modular components your team can build on.
Elena, Chloe and Daniel are independent specialists who partner with finalcoat.dev on client projects.
Can't find what you're looking for? We usually reply within one business day.
Ask us anythingAlmost never. We build on what you have. If the Inspection finds something that genuinely can't be saved, we'll tell you plainly and explain the options before you spend anything more.
Most apps built with tools like Cursor, Claude Code, Lovable, Bolt, Replit and v0, and the stacks they produce: React, Next.js, Node, Python, Supabase, Firebase, Postgres, Vercel, Cloudflare and more. If you're unsure, send us a link.
No. If you got your app working, you're technical enough. We explain everything in plain English and record walkthroughs so you can keep building afterwards.
You do. Everything we build for you is yours once the invoice is paid. See our Terms for the details.
For Final Coat you pay a 30% deposit to start, then we agree a fixed scope and price in writing. If we can't agree a scope, we refund the deposit less any work already delivered.
Yes. Confidentiality is built into our Terms, and we're happy to sign yours too.
Tell us what you've built and where you're stuck. We'll reply within one business day with honest next steps, even if that's "you don't need us yet".
Send us a link to your app or repo and a few lines about what you need.
Book an Inspection and within a week you'll know exactly what stands between you and launch.
