About this gig
Your product isn't real until people can click it.
That perfect version in your head? Investors can't see it. Users can't test it. Nobody can pay for it. Markets reward shipped products not roadmaps.
That's where I come in.
I build lean, functional, launch-ready MVPs for founders, creators, and early-stage startups in 21 days. No feature bloat. No six-month build. Just the core engine that solves one painful problem so you can launch, get real users, and start selling.
What you get:
- A working, clickable MVP web app, mobile app, or SaaS platform
- Modern scalable stack: React, Next.js, TypeScript, Node, Python, Postgres/Supabase
- Auth, database, payments, dashboard, admin panel wired and working
- Clean responsive UI/UX that doesn't look like a prototype
- Daily progress updates. Weekly demo calls.
- Launch-ready in 21 days or less
We lock your core feature set and scope in writing before day one, so there's zero ambiguity and zero scope creep.
Ideal for: MVP development, SaaS MVP, startup web app, mobile app MVP, prototype to production, investor demo builds.
Time kills deals. Let's get your MVP live before your competitors ship theirs.
Message me with your idea and I'll tell you exactly w

I build MCP servers that connect AI models to the systems a business already runs on. Working in Python and TypeScript with the Model Context Protocol, I wire Claude, Cursor, and custom agents into your APIs, databases, and internal tools — with scoped permissions, real error handling, and documentation a teammate can actually follow. I also build AI integrations and automation backends for teams moving past prototypes into production. If you want your AI to do the work instead of describing it, send me your use case.

FAQ
Can you fix my Lovable, Bolt, Base44 or Replit app that is broken?
Yes — that's my speciality. I find the root cause of the issue and fix it properly so it stays fixed. Message me with a brief description and I'll confirm if it's covered before you order.
What if I am not happy with the result?
Every package includes revisions — 2 for Rescue, 3 for Launch, unlimited for Scale. If the delivery doesn't match what we agreed before the order, I revise it until it does. I don't consider a project finished until you're satisfied.
My project is more complex than your packages — can you still help?
Yes. My packages are starting points, not hard limits. If your project needs more screens, more APIs, or more custom logic, message me with the details and I'll send you a custom offer priced fairly for the actual scope. I'd rather scope it correctly upfront than have surprises mid-project.
Can you work on an app that was built by someone else or by an AI tool?
Absolutely — this is the majority of my work. Whether your app was built on Lovable, Bolt, Base44, Replit, or by a previous developer, I can audit, fix, and extend it. Share the project details or a GitHub link and I'll review it before you order to confirm what's needed.
Do you offer ongoing maintenance after the project is done?
Yes. Beyond the included post-delivery support window, I offer ongoing maintenance as a separate arrangement. If you want a developer on call for updates, bug fixes, and new features after launch, message me and we can discuss a retainer or per-task arrangement that fits your needs.
How is your work different from other vibe coding freelancers on Fiverr?
Most sellers in this category are non-technical — they re-prompt AI tools and deliver the output as-is. I'm a trained full-stack developer who uses AI as a tool, not as a replacement for understanding. I know why code breaks, how to structure it to scale, and how to secure it for real users.
