Fullstack Developer Next.js & Supabase
Audit Vibe Coding & SaaS Platform Creation
Hello, I'm Ruddy.
Today, anyone can prototype an app in a few hours with Lovable, Bolt.new, Cursor, or v0. The problem is that moving to production often reveals huge technical debt, security vulnerabilities, and code that no one understands six months later.
That's exactly where I come in.
What I do
I am a fullstack developer and founder of the SaaS ZenApply.io. On a daily basis, I build and industrialize modern web platforms using a Next.js, Supabase, TypeScript, and TailwindCSS stack.
My offer is structured around three complementary areas.
1. Audit & Refactoring of "Vibe Coded" Projects
Did you start on Lovable, Bolt, or Cursor and want to take it to the next level? I audit your project (security, architecture, performance, technical debt), provide you with a clear and quantified roadmap, and then I can properly refactor the foundation to move it to a real production environment.
2. Creation of Web Platforms & SaaS
I design and develop your SaaS, MVPs, dashboards, and back-offices from scratch. Modern stack, clean and tested code, scalable architecture. From product scoping to deployment.
3. Consulting & Training
Stack choices, architecture, API integrations (Stripe, n8n, OpenAI), Vercel or Docker VPS deployment. I also train your tech teams in mastered "Vibe Coding" and best practices for Next.js / Supabase.
My Technical Stack
Front: Next.js 15, React, TypeScript, TailwindCSS, Shadcn UI
Back: Supabase, PostgreSQL, Prisma, tRPC, REST API
DevOps: Vercel, Docker, VPS, Git
AI & Auto: Claude Code, Cursor, n8n, AI Agents
Shall we discuss it?
Whether it's for an audit, a redesign, or a creation from scratch, let's talk about your project.
