About this gig
Started your app in Replit, Cursor, Lovable or Bolt and need a developer to finish it properly? Or need a real SaaS MVP that does not break? I'm your Replit developer and Cursor developer for vibe coding projects: I build your SaaS MVP or finish the one your AI tool started, with login, database, admin dashboard, Stripe payments, deployed on your own domain.
We're a two-founder software studio. We build web apps with admin panels for real businesses and built our own factory ERP in under a month.
WHAT YOU GET
- A clear feature plan before we start, so the MVP stays small and launchable
- Your Replit or Cursor project finished, or a new Next.js + Supabase app: auth, secure database rules, admin dashboard
- Stripe payments or subscriptions (Standard and Premium)
- Deployed live on Vercel or Cloudflare, on your accounts. You own all the code
- Clean code you (or your AI tool) can keep building on
HOW WE WORK
- Send your idea, the must-have features and any designs or examples
- I reply with a feature plan and confirm the package
- You get progress updates, a live preview, then the launch
Not sure what fits in an MVP? Message me and I'll help you cut it down.

I'm Ruwithma, co-founder of a two-person software studio in Colombo. We build with AI tools every day, so we know where AI-built apps break and how to fix them properly.
What I do:
- Fix and deploy apps built with Lovable, Bolt, Cursor or Replit
- Build SaaS MVPs with Next.js and Supabase
- Set up Claude Code for your team: skills, MCP servers and agents
- Custom GPT and Claude assistants trained on your documents
Everything is tested and runs on your own accounts, and you own all the code. Message me with what you need. I reply within a few hours.

FAQ
Can you work from my Figma, Lovable or Bolt prototype?
Yes. I rebuild or extend it into a clean Next.js + Supabase app you own.
Who owns the code and accounts?
You do. Everything runs on your own Supabase, Vercel and Stripe accounts, and the code goes to your GitHub.
What if I need more features later?
Message me after launch and I'll send a custom offer for the next set of features.
Do you use AI tools?
Yes, to move fast, but every line is reviewed and tested by us. That's the difference from a raw AI-built app.
Can I see an app you built?
Yes: ShiftNote in my portfolio, a working shift-planning SaaS demo with login, team roles, a staff view and Stripe billing. 46 of 46 automated tests pass.
Why Next.js and Supabase?
Fast to build, cheap to run and easy to hire for later. Supabase gives you a real PostgreSQL database, login and file storage in one place.
What will hosting cost me?
Small MVPs often start on free tiers. A paid production setup is usually about $20 to $45 a month for Supabase and Vercel, billed to your own accounts.
Is my users' data secure?
Every table has row-level security, so users only see their own data, and payments are confirmed on the server, never in the browser. I test both before launch.
Will it work on phones?
Yes, every screen is responsive and tested on mobile. Native App Store apps are not in these packages; message me if you need one.
What if something breaks after launch?
If something I built doesn't work as agreed, tell me and I'll fix it. New features after delivery get a custom offer.
