About this gig
MERN stack developer for SaaS platforms, web apps, dashboards, vibe-coded MVP completion.
I'm Mustafa, full-stack developer, 10+ years building production software for healthcare, fintech, and SaaS companies. MongoDB, Express, React, Node.js, Next.js - architecture, backend, database design, deployment, end to end.
SaaS MVPs built in Bolt, Lovable, Cursor, or Replit often stall at 80% complete: frontend looks right, backend and database aren't production-ready. I finish that work, or build SaaS platforms from scratch with proper architecture.
What I build:
- MERN stack SaaS platforms, web apps, admin dashboards
- Backend architecture, database design, MongoDB schema
- REST APIs, GraphQL, third-party integrations
- Authentication, roles, subscriptions, Stripe payments
- CRMs, internal tools, marketplace platforms
- Vibe-coded MVP completion, hardening, deployment
Why work with me:
- 10+ years real engineering, not prompt engineering
- Proper architecture every project, not just working code
- On-time delivery, 30 days free support after completion
Message before ordering to scope project requirements.

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.

FAQ
Can an MVP built in Bolt, Lovable, or Cursor be finished and made production-ready?
Yes — common project type. AI-generated frontend stays, real backend gets built underneath: database, authentication, APIs, deployment, production hardening
Full SaaS platform build, or partial backend work only?
Both. Complete SaaS platforms built from scratch, or specific parts: backend architecture, API integrations, database design, subscription and payment systems.
Process for new SaaS or MERN stack projects?
Scoping conversation first, then architecture planning before development starts. MongoDB schema, API structure, and auth flow mapped out before any code — prevents rebuilds later.
Payment and subscription integration for SaaS apps?
Yes — Stripe integration, subscription tiers, role-based access, billing logic included in full SaaS builds.
Post-delivery support included?
Yes — 30 days free support for bugs and adjustments. Long-term maintenance and feature development available as ongoing arrangement.
