How I build client MVPs in 3 weeks (no big team needed)

In partnership with

Hey builders,

Most agencies take 3 months and $50K to build an MVP. They need designers, frontend devs, backend devs, project managers.

I build the same MVPs in 3 weeks at 1/10th the cost. Solo, or with just one other person.

Here’s my exact AI-powered workflow:

Step 1: Plan using ChatGPT

Before touching any code, I plan everything fast:
• ChatGPT voice to brainstorm the client idea
• Generate all docs (PRD, UI Dev Plan, DB design)
• Use MoSCoW Method to define what's essential

This gives me:
• A clear feature list
• A lean scope
• Zero ambiguity about what to build

Most builders skip this step and wonder why their AI keeps building the wrong thing.

Step 2: Skip traditional design, go straight to dev

Most devs waste weeks designing in Figma.

I use Lovable instead.

It:
• Turns text into full responsive UIs
• Connects real data
• Handles auth, forms, routing

I build 70-80% of the MVP inside Lovable (depending on complexity), then switch to Cursor for the advanced stuff.

Step 3: If design is needed, use UX Pilot

I usually skip design completely. But when clients want visuals first, I use UX Pilot.

It:
• Generates high-quality screens from prompts
• Maps out full user flows
• Lets me adjust branding, colors, layouts in minutes

This way, I can show polished screens fast without wasting weeks in design tools.

Step 4: Sync to GitHub → Continue in Cursor

Lovable syncs everything to GitHub automatically.

Then I open the repo in Cursor, my AI coding assistant.

Cursor:
• Understands the full codebase
• Makes edits across multiple files
• Writes and optimizes backend logic
• Refactors APIs and improves performance

It's like having a 10x junior developer on command.

Step 5: Use MCP to automate database work

Model Context Protocol (MCP) connects Cursor to Supabase in real time.

With MCP:
• Cursor queries the live database
• Generates and applies migrations
• Updates models without manual SQL

This kills 80% of backend grunt work.

Step 6: Use CodeRabbit for code reviews

CodeRabbit checks my code before shipping.

It:
• Flags security issues early
• Spots messy or slow code
• Suggests cleaner, scalable patterns

I run reviews in Cursor during development, and again at the GitHub stage. Clean, secure code every time.

Step 7: Supabase for backend, auth, and real-time

I use Supabase to avoid backend headaches:
• Built-in user authentication (OAuth, Magic Links)
• Row-level security for safe access
• Postgres database with instant scaling
• Edge Functions for serverless logic
• File storage and uploads

Step 8: Take security seriously

Before launch, I follow a simple checklist:
• Enable Row-Level Security
• Add rate limiting
• Use CAPTCHA on auth forms
• Keep API keys hidden
• Validate everything server-side
• Run CodeRabbit security scan

Build fast, build safe.

Step 9: Deploy in minutes with Vercel

No complicated setup needed.

Vercel:
• Auto-syncs from GitHub
• Global CDN for instant speed
• Serverless backend functions
• No manual configurations

Client gets a live product in Week 3.

The result: A working MVP in 3 weeks

With this workflow I've:
• Built 40+ MVPs solo or with a small team
• Scaled IgnytLabs to $200K+
• Helped founders validate ideas without spending $20K-$30K upfront

You don't need big teams or endless planning.

You need a workflow that combines:
• Cursor (AI coding assistant)
• Lovable (UI builder)
• UX Pilot (optional design)
• Supabase (backend)
• Vercel (deployment)
• CodeRabbit (code reviews)
• ChatGPT (planning)

This is what I call "Vibe Coding." Learn it, and you'll build faster, smarter, and cleaner.

The bigger picture:

While other agencies are still hiring teams and managing complex workflows, AI-first builders are shipping complete products in the time it takes them to finish a wireframe.

The gap is only getting bigger.
