About this gig

Are you a startup founder or business owner who needs a working SaaS product, not just a landing page?


I'm Joan, a full stack software engineer with 4+ years of production experience building SaaS platforms for fintech, healthtech, and business tools. I currently work on MedFlow, a Swiss medical AI SaaS platform, and I built iTracker, a multi-tenant issue tracking system, from the ground up.


I can help you go from idea to a functional, production-ready SaaS application, including:

  • User authentication and role-based access
  • Custom dashboards and admin panels
  • Database design and backend architecture
  • Payment and subscription billing integration
  • Multi-tenant architecture (if your product needs it)
  • API integrations
  • Deployment and hosting setup


Tech I work with: React, Next.js, Node.js, Express, PostgreSQL, Prisma, Supabase, Vue.js, TypeScript.


Whether you need an MVP to validate your idea or a full-featured platform ready for real users, I'll build it clean, functional, and scalable.


Let's talk about your project. Send me a message before ordering if you're not sure which package fits your needs; I'm happy to help you scope it out.
