I build backend foundations for subscription-based SaaS products using .NET Core / Node.js / Python / PHP with secure API design and scalable architecture. If you need a robust SaaS core (multi-tenant readiness, authentication, billing flows, and integrations), I’ll deliver a production-ready backend you can grow with.
Includes: domain modeling, REST/GraphQL APIs, auth (JWT/OAuth), subscription/billing integration, background jobs, database design, CI/CD, and cloud deployment.
Ideal for: MVP-to-production SaaS, subscription products, intake/automation platforms, and API-first systems.
