Project details

Did you build your React or Next.js app with AI, but now the code is messy, unstable, buggy, or hard to launch?

I will help you clean up AI-generated code, fix broken logic, repair React/Next.js issues, resolve TypeScript errors, improve structure, and prepare your app for real users.

This project is perfect if you used ChatGPT, Cursor, Lovable, Bolt, v0, Windsurf, or another AI tool and now your app looks close to finished but has bugs, broken API calls, bad architecture, duplicated code, or deployment problems.

I can help with React components, Next.js App Router issues, TypeScript errors, state management, API integrations, authentication, Stripe, Tailwind CSS layout bugs, environment variables, Vercel deployment, VPS setup, PM2, Nginx, and production-readiness cleanup.

Before starting, I will review your project and confirm what can be fixed within the selected package. If the issue is bigger than the package, I will clearly explain the best next step.

Coding Front-End SaaS I had the pleasure of working with Vasyl P. on a frontend project, and I couldn’t be more satisfied with the results. He delivered high-quality, well-structured, and responsive code, ensuring a seamless user experience.

Communication was excellent throughout the project—Vasyl P. was always responsive, proactive, and open to feedback. He not only met all the requirements but also suggested valuable improvements that enhanced the final product.

If you’re looking for a skilled, reliable, and detail-oriented frontend developer, I highly recommend Vasyl. I would definitely work with him again in the future!

Full-Stack SaaS Developer | Next.js, NestJS, React

Chernivtsi, Ukraine - 12:38 pm local time
I help startups, agencies, and business owners build, fix, and launch production-ready web apps using Next.js, React, NestJS, TypeScript, and modern full-stack architecture.

If your project is half-built, buggy, slow, AI-generated, or stuck before launch - I can step in, clean it up, fix the architecture, and turn it into a stable product.

I have 10+ years of development experience and 50+ projects delivered outside Upwork, including SaaS platforms, e-commerce websites, admin dashboards, mobile apps, payment integrations, APIs, CMS integrations, and deployment to production.

What I can help you with:

✅ Full-stack SaaS/MVP development
✅ Next.js apps with React, TypeScript, Tailwind CSS
✅ NestJS backend, REST APIs, Prisma, PostgreSQL/MongoDB
✅ Stripe payments, subscriptions, checkout flows
✅ Admin dashboards, CRM panels, internal tools
✅ Bug fixing, refactoring, performance optimization
✅ AI/vibe-coded project cleanup and stabilization
✅ Strapi CMS, Firebase, authentication, RBAC
✅ Deployment: VPS, PM2, Nginx, Vercel, DigitalOcean, AWS
✅ React Native mobile apps for iOS and Android

My working style is simple: I don’t just “write code”. I look at the product, business goal, user flow, architecture, performance, and long-term maintainability.

You can hire me when:

• your app works, but has bugs and bad code
• your previous developer disappeared
• your AI-generated code is messy and unstable
• you need a clean Next.js frontend
• you need a reliable NestJS backend
• you need Stripe, CMS, auth, API, or deployment done properly
• you want someone who can own both frontend and backend

Tech stack:
Next.js, React, TypeScript, JavaScript, NestJS, Node.js, Prisma, PostgreSQL, MongoDB, Strapi, Firebase, Stripe, Tailwind CSS, Zustand, React Query, React Native, AWS, DigitalOcean, Vercel, PM2, Nginx.

If you need a developer who can take responsibility for the whole product - frontend, backend, integrations, deployment, and fixing messy code - send me a message and I’ll suggest the best next step.
