You will get your AI-generated web app fixed and stabilized
Project details
Did you build a web app with Replit, Lovable, Bolt, Cursor, ChatGPT, or another AI/vibe-coding tool, but now it has broken flows, auth issues, failed API calls, database problems, deployment errors, or unstable code?
I help founders and small teams review, fix, and stabilize AI-generated web apps so they can become usable MVPs.
Depending on the package, I can audit the codebase, identify what is broken, fix agreed priority flows, improve backend/API/database integration, resolve auth or deployment issues, test the main user journey, and provide clear handoff notes.
This service is best for early-stage apps where the prototype exists, but the product needs a real developer to make it work reliably.
Important: this is not unlimited development or a full rebuild by default. If the generated code is too unstable, I will explain the risks and recommend whether it should be fixed, refactored, or rebuilt.

About Stefan
AI Integration & SaaS MVP Developer | Web & Mobile Apps
Skopje, North Macedonia - 4:02 am local time
My main strength is combining product thinking with clean implementation. I can help you clarify scope, break the work into practical milestones, build the first usable version, and prepare it for real users without overengineering the MVP.
I also help teams add useful AI features into existing products: AI chatbots, SaaS assistants, document summarization, AI-powered search, workflow automation, and OpenAI/Claude API integrations.
My working style is clear, structured, and outcome-focused: I clarify requirements, align expectations early, and take ownership of moving the project toward a usable MVP.
What I can help with:
• SaaS/web apps: React dashboards, admin panels, customer portals, and landing pages
• AI integrations: OpenAI/Claude API, AI chatbots, SaaS assistants, document summarization, and AI workflow features
• Backend: APIs, authentication, databases, integrations, Supabase/PostgreSQL, and deployment-ready architecture
• Mobile apps: iOS/SwiftUI and React Native
• MVP delivery: feature planning, technical architecture, implementation, QA, and release support
• Design-to-development: I can work from existing Figma designs or collaborate with a trusted UI/UX designer when the project needs both design and development
Best fit:
• You need a first MVP, prototype, or v1 product
• You want to add AI into a SaaS/web app without overcomplicating the product
• You have an AI-generated/vibe-coded prototype that needs to become stable and functional
• You prefer clear milestones, practical scope, and fast delivery
• You need web + backend + AI coordination without managing several separate developers
I focus on practical AI integrations inside real products, not custom machine learning model training from scratch.
