Case Study

Conslinq

Conslinq is a tenant-aware case management platform that shows how I build secure, business-focused web apps for complex workflows.

Conslinq

The challenge

The system needed to support multiple roles, data isolation, and secure access to sensitive immigration workflows without sacrificing usability or speed.

The solution

I structured the app with Next.js on the frontend, FastAPI for backend logic, and Supabase PostgreSQL for secure, tenant-aware data access.

What this delivered

  • A clearer product story for users and stakeholders
  • Secure multi-role access patterns with row-level security
  • A strong proof page for people searching for Next.js and FastAPI work
