SaaS Development Using AI

Software as a Service is the dominant business model in modern tech. Subscription-based software products generate recurring revenue month after month — and with AI powering the core features, you can now build products in weeks that would have taken teams of engineers months just a few years ago. This diploma teaches you exactly how to do it.

You will learn how to build complete, production-ready SaaS products using PHP, .NET, or Java — integrated with the OpenAI API and other AI services — complete with subscription billing, user dashboards, payment processing, and scaling strategies. Every concept is taught by Debasis Bhattacharjee, a working AI Developer and Software Architect who has built and shipped real SaaS products used by real customers.

Why AI-Powered SaaS Is the Biggest Opportunity in Tech Right Now

AI APIs have made it possible for individual developers to build products that genuinely compete with funded startups. A single developer with the right skills can build an AI writing tool, an AI customer service system, or an AI data analysis product — and charge subscribers £20, £50, or £200 per month. The barrier to entry has never been lower. But the knowledge required to build a complete, working, monetised SaaS product is still very specific — and this diploma gives you all of it.

What You Will Actually Build

• Project 1 — AI Content Generation Tool: A web-based SaaS application that uses the OpenAI API to generate blog posts, product descriptions, or marketing copy — with user accounts, usage limits, and a subscription plan.
• Project 2 — AI Customer Support System: A deployable AI chatbot product with a customisable knowledge base, conversation history, and a multi-tenant architecture that allows different businesses to run their own branded version.
• Project 3 — Full SaaS Product with Billing: A complete SaaS product with Stripe subscription integration, a tiered pricing model, a user dashboard, admin panel, usage analytics, and a landing page — ready to launch.

What You Will Learn

• OpenAI API Integration: Chat completions, embeddings, fine-tuning, function calling, and managing tokens and costs in a production system.
• SaaS Architecture: Multi-tenancy, database design for subscription products, API rate limiting, and building systems that scale.
• Subscription and Billing Systems: Stripe integration, subscription plans, trial periods, upgrade/downgrade flows, invoice generation, and webhook handling.
• User Authentication and Security: Registration, login, email verification, password reset, role-based access, and protecting AI API keys.
• Admin Dashboards and Analytics: Building admin panels to manage users, monitor usage, handle support, and track revenue metrics.
• Deployment and Scaling: Deploying to cloud servers, setting up SSL, managing environment variables, caching strategies, and preparing for traffic growth.

Who This Course Is For

This diploma is designed for developers who already have a working knowledge of at least one backend language — PHP, .NET, or Java. It is ideal for developers who want to launch their first SaaS product, freelancers who want to build AI-powered tools for clients, and entrepreneurs who want to turn a software idea into a subscription business.

Batch Classes vs 1-on-1 Mentorship

The Batch format runs weekly live sessions focused on building and shipping. The 1-on-1 Mentorship format gives you direct guidance from Debasis on your specific product idea — architecture decisions, AI integration, billing setup, and launch strategy. Both cover the full curriculum.
