About this gig
Want an AI-powered website, SaaS platform, or app that actually holds up under real users - not just a working demo?
I'm Mustafa, a full-stack and AI developer with 10+ years building production software for healthcare, fintech, and SaaS companies. I build AI apps from scratch, and I also take vibe-coded prototypes from Lovable, Base44, Bolt, or Replit and turn them into secure, production-ready products.
Most AI-generated apps look fine in a demo and break under real traffic - broken auth, no real backend, security holes. I fix that, or build it right from day one.
What I can build for you:
- AI websites and web applications
- Custom SaaS platforms and admin dashboards
- AI chatbots and automation systems
- Full-stack development, frontend to backend
- Secure database and backend architecture
- User auth, roles, and payment integration
- Fixing and deploying vibe-coded apps
Why work with me:
- 10+ years of real engineering, not prompt engineering
- Every line of AI-generated code gets reviewed before it ships
- On-time delivery, 30 days of free support after completion
Message me before ordering so we can scope your project properly.

I'm Mustafa. Ten years writing software in healthcare platforms, fintech tools, SaaS products, mobile apps in Flutter and React Native. I use AI constantly to move faster, but the real engineering is still mine: backend, security, database design, the parts that break at 2am if you get them wrong.
Vibe-coded something in Lovable, Base44, Bolt, or Replit and it's cracking under real traffic? That's usually me getting called in and I fix what broke, lock down security, deploy it properly. Or I'll build it right, full-stack, Node.js, Next.js, and Python under the hood, start to finish.
My Portfolio
FAQ
What type of projects do you work on?
AI-powered websites, SaaS platforms, and full-stack web apps. I also fix and deploy vibe-coded prototypes built in Lovable, Base44, Bolt, or Replit - turning a working demo into something that handles real traffic and real users.
How do you ensure the quality of your work?
Every project gets proper backend architecture, security checks, and testing before delivery, not just a working demo. If AI tools are involved, I review the generated code myself before it ships. 10+ years of engineering habits don't disappear just because the tools changed.
Can you provide ongoing support for my project?
Yes - every package includes 30 days of free support after delivery for bugs or small adjustments. If you need longer-term help, we can set up an ongoing arrangement once we've talked through what you actually need.
