About this gig

Looking to build a real SaaS product, not just a demo?


I specialize in SaaS architecture and will build a secure, scalable multi-tenant SaaS backend using Next.js, Sanity CMS, and a production-ready database architecture.


This gig is for founders, startups, and agencies who need a clean SaaS foundation that can scale from 10 users to 100k+ without rewriting everything later.


I design multi-tenant systems with proper tenant isolation (shared or separate databases), role-based access control, secure authentication, and optimized API performance. Your backend will be structured for growth, security, and maintainability, not shortcuts.


Using Next.js, I ensure fast server-side logic and API handling. With Sanity, you get a flexible CMS for managing content, plans, users, and app data. The database architecture is carefully designed to avoid common SaaS scaling mistakes.


Whether you're launching an MVP, rebuilding a broken SaaS backend, or planning a long-term platform, Ill guide you with clear technical decisions and free consultation before we start.


If you want a future-proof SaaS backend, this gig is built exactly for that.
