Over deze dienst
Stop fighting AI bugs and start scaling your vision.
Replit AI and Base44 are great for prototypes, but they often leave you with "spaghetti code," unstable APIs, and deployment errors. AI can generate code, but it doesn't build production-ready products. Thats where I come in.
I specialize in taking "vibe-coded" apps and turning them into high-performance SaaS platforms. Whether you're a startup founder or an agency, I bridge the gap between a messy script and a scalable application.
What I Solve for You:
- Architectural Cleanup: Refactoring AI code into clean, modular structures.
- Performance: Fixing lag and ensuring smooth user experiences.
- Stability: Solving broken Auth flows and unstable API integrations.
- Deployment Mastery: Getting you out of "Deployment Hell" and live.
- Feature Expansion: Adding complex logic that standard prompts miss.
What you will get:
- Fix broken Replit AI/Base44 web apps
- Refactor messy AI code
- Improve speed & performance
- Build AI web apps from scratch
- API & AI integrations
- Production-ready apps

Veelgestelde vragen
What types of issues can you fix in my Base44 project?
I resolve critical problems such as failed deployments, broken features, authentication errors, database connection issues (Supabase), API failures, and performance bottlenecks. I go beyond quick fixes by identifying and resolving the root cause to prevent future issues.
Can you fix my Supabase authentication or database errors?
Yes. I specialize in Supabase Auth, Row Level Security (RLS), SQL migrations, and real-time database issues. Whether it's login failures, permission errors, or broken queries, I ensure your backend works securely and efficiently.
My app won’t deploy on Vercel or Replit can you help?
Absolutely. Deployment failures are one of the most common issues I handle. I troubleshoot build errors, environment variables, misconfigurations, and ensure smooth deployment on Vercel, Replit, Netlify, or Docker.
Do you only fix issues, or can you build features too?
Both. I fix existing bugs and also develop core features like authentication systems, CRUD operations, AI integrations, and full MVP functionality tailored to your project goals.
Can you help me build and launch my MVP quickly?
Yes. I specialize in rapid MVP development using Base44, Supabase, and AI tools. My focus is getting your product live fast, functional, and ready to validate with real users.
How do you ensure my app won’t break again after fixing it?
I don’t just patch issues I analyze the architecture, fix underlying problems, optimize workflows, and apply best practices to ensure long-term stability and scalability.
Can you integrate AI features into my application?
Yes. I can implement AI-powered logic, automation, and integrations to enhance your app’s functionality, whether it’s chat features, workflows, or smart automation.
What platforms and tools do you work with?
I work with Base44, Supabase, Bolt, Replit, Vercel, Netlify, lovable, Docker, RunPod, n8n, and modern frontend frameworks. I choose the best stack based on your project needs.
How fast can you deliver fixes or features?
Turnaround time depends on complexity, but I prioritize speed and efficiency. Most critical fixes are handled quickly, and I communicate clearly throughout the process.
What do you need from me to get started?
I’ll need access to your codebase (GitHub/Replit), a clear description of the issue, any error logs, and your deployment setup. The more details you provide, the faster I can diagnose and resolve the problem.
