I WILL BUILD A SECURE SAAS MVP WEB APP USING NEXT.JS, REACT & SUPABASE


>>> Ready to turn your idea into a real SaaS product?


I'm a fullstack developer AND a certified ethical hacker (CEH, CND, CompTIA Security+) 

which means your SaaS isn't just built fast, it's built to survive real-world attacks. 

Most developers bolt security on as an afterthought. I test for vulnerabilities the same 

way attackers would, then build the fix in from day one.


WHAT I BUILD:

  • SaaS web applications & MVPs
  • CRM / admin dashboards & internal tools
  • Subscription & multi-tenant platforms
  • User authentication & role-based access systems
  • API-driven applications
  • AI-powered web app features (on request)


CORE FEATURES INCLUDED:

  • Secure authentication (JWT / OAuth / Supabase Auth)
  • Database architecture (Supabase, PostgreSQL, Firebase)
  • API development & third-party integrations (Stripe, etc.)
  • Clean, responsive UI (Tailwind CSS)
  • Scalable project structure, ready to grow past MVP


Every SaaS is different message me before ordering so we can scope your MVP clearly. Let's build something that's fast to market and hard to break.
