Your SaaS idea deserves an architecture that won't break when you scale.

I specialize in multi-tenant platforms, subscription billing, and role-based access — built with Next.js and NestJS from day one, not bolted on later.

What I've built:
— InvoiceFlow: Multi-client billing SaaS with automated invoicing and real-time payment tracking across tenants
— SecureVoIP: Full-stack VoIP & billing platform with secure auth and call management
— Multi-Tenant SaaS Starter Kit: RBAC and billing logic built in from the ground up

I also integrate AI where it adds real value — RAG chatbots, LangChain pipelines, OpenAI/Gemini.

Let's talk about what you're building. I'll tell you what's missing before we start — not after.
