SaaS Application Development

Turn your idea into a scalable, cloud-native Software-as-a-Service product. I build secure multi-tenant SaaS applications using .NET and Vue.js — architected to grow from your first 10 users to 10 million, with the billing, access control, and observability infrastructure that modern SaaS products demand.

What's Included

  • ✓Multi-tenancy Architecture — Design and implement isolated-tenant or shared-schema multi-tenancy in ASP.NET Core, ensuring robust data separation, per-tenant configuration, and white-labeling support from the ground up.
  • ✓Subscription Billing & User Management — Integrate Stripe billing with subscription plans, trial periods, usage-based pricing, and a full user and organization management system with role-based permissions and invitation flows.
  • ✓Cloud-Native Deployment (Azure / AWS) — Infrastructure-as-code deployment using Docker containers, Azure App Service, Azure Container Apps, or AWS ECS for automated horizontal scaling and zero-downtime releases.
  • ✓Secure API Development — OAuth 2.0 / OpenID Connect authentication, JWT-based authorization, rate limiting, audit logging, and comprehensive input validation for a production-grade security posture.

Technologies & Stack

ASP.NET Core (.NET 8), C#, Vue.js 3, Nuxt.js, Tailwind CSS, PostgreSQL, SQL Server, Redis, Stripe API, Docker, Azure App Service, Azure Container Apps, GitHub Actions, Entity Framework Core, MediatR (CQRS).

Who This Is For

This service is designed for founders and product teams building a new SaaS product, companies migrating a legacy on-premise tool to a cloud-based subscription model, and businesses looking for a freelance SaaS developer with full-stack .NET and Vue.js expertise. I handle the full lifecycle — from architecture and MVP to production deployment and feature iteration — so you can focus on your market rather than your infrastructure.
