Architectural Overview & Implementation Strategy

Moving from an idea to a production platform requires intentional architecture. I construct robust, multi-tenant web applications engineered for scalability using Next.js 15, Node.js, and PostgreSQL database scaling. From building RESTful microservices, JWT/OAuth authentication, and real-time WebSocket pipelines, your platform is built to handle thousands of concurrent users, demonstrated in Daily Report and IYF Platform.

Ideal For

B2B SaaS startups, technical founders, and enterprises replacing fragile legacy software with modern web platforms.

Core Capabilities & Technical Standards

Frequently Asked Questions

What backend stack do you use for SaaS platforms?

I specialize in Node.js and Express.js paired with PostgreSQL (hosted on AWS RDS, Supabase, or Neon DB) and Redis for in-memory session caching. This stack provides extreme speed, predictable horizontal scaling, and complete type safety.

How do you handle multi-tenancy and data isolation?

Depending on compliance requirements, I implement either schema-based multi-tenancy or tenant-isolated row-level security with tenant ID foreign keys enforced at the ORM and database constraint layer.

Can you build subscription billing into my SaaS?

Yes. I implement complete subscription lifecycle management using Stripe Billing or Lemon Squeezy, handling plan upgrades, prorated billing, failed payment grace periods, and customer self-serve portals.
