You will get a production-ready web app from your AI prototype

Project details
I help founders turn fragile AI-generated prototypes into stable, production-ready web apps.
If your app was built with tools like Lovable, Bolt, v0, Replit or an AI coding assistant and now has broken flows, unstable auth, database issues, API errors, payment bugs, deployment failures or messy code, I can help you clean it up and make it launch-ready.
Depending on the package, I can audit your codebase, identify production risks, fix critical blockers, stabilize your main user flow, clean up integrations, improve deployment setup and prepare your app for real users.
I am a senior full-stack developer with 15+ years of experience, Fiverr Pro-vetted, Envato Elite Author, and creator of commercial WordPress products used by 30,000+ customers.
This project is ideal if your prototype looks promising but is not reliable enough for clients, investors, paid traffic or public launch.

About Charly
Senior Full-Stack Engineer | React, Node, PHP, WordPress, WooCommerce
Tarnos, France - 5:16 am local time
I help founders, agencies, and product teams turn unstable, slow, half-finished, or over-complicated web systems into reliable production software.
My background combines deep frontend, backend, WordPress/WooCommerce, SaaS, API integrations, payment systems, automation, AI-powered features, performance optimization, and production debugging.
I am trusted by 30,000+ users through my premium WordPress and WooCommerce plugins sold on CodeCanyon, where I became an Envato Elite Author. I have also completed 270+ freelance projects on Fiverr with a 4.9★ rating and Fiverr Pro-vetted status.
I am new to Upwork, not new to delivery.
WHAT I CAN HELP YOU WITH
• Full-stack web application development
• SaaS MVP development and production fixes
• React / JavaScript / TypeScript frontend development
• PHP, WordPress, WooCommerce and custom plugin development
• API integrations, automation workflows and payment systems
• WooCommerce performance, checkout and tracking issues
• Core Web Vitals optimization: LCP, CLS, INP
• Backend debugging, technical audits and architecture reviews
• AI-powered features, internal tools and business dashboards
• Migration from no-code/prototype tools to production-ready platforms
WHO I WORK WITH
• Founders who need a serious technical partner, not just someone who “knows a bit of code”
• Agencies needing a senior white-label developer they can trust
• WooCommerce store owners losing money because of technical issues
• SaaS and app owners who need to stabilize, finish or scale their product
• Businesses with messy existing systems that need clean, safe, production-grade fixes
HOW I WORK
1. I first understand the business problem, not just the technical symptom.
2. I identify risks, hidden complexity and the fastest safe path forward.
3. I give you a clear scope, fixed quote or structured roadmap.
4. I work staging-first when needed, with backups and rollback planning.
5. I document what was changed, why it mattered, and what to watch next.
WHAT MAKES ME DIFFERENT
I am not a junior developer learning on your budget.
I have spent 15+ years shipping real products, maintaining complex client systems, building commercial plugins used by tens of thousands of users, fixing production issues, and dealing with the kind of edge cases that only appear once real money, real users and real deadlines are involved.
That matters.
Because building software is easy when everything goes right. The value of a senior engineer appears when things are unclear, broken, slow, fragile, undocumented, or halfway built by someone who has mysteriously “become unavailable”.
WHAT I DON'T DO
I do not take vague “make it better” jobs with no clear goal.
I do not do cheap cosmetic page-builder edits.
I do not recommend full rebuilds when a targeted fix is enough.
I do not create technical debt just to deliver something that looks finished for two weeks.
If you need a senior full-stack engineer who can understand the product, fix the real problem, and deliver clean production-ready work, I can help.

Revisions may occur after the delivery date.
Requirements review
I review your app link, codebase access, tech stack, reported issues, priority user flow and success criteria.
Technical diagnosis
I inspect the code, architecture, deployment setup, integrations and main blockers to confirm the project scope.
