FAQ
What do you need from me to get started?
I’ll need a clear idea of your SaaS concept, target users, core features, and preferred platforms (web, social media, payments, etc.). If you already have designs, workflows, or examples, that’s great—but if not, I can help you shape the technical scope.
Do you also help with MVP planning and architecture?
Yes. If you’re in the MVP stage, I’ll help you decide what to build first, how to structure the backend, and how to use AI and MCP servers efficiently so you don’t overbuild.
What is an MCP server and why should I use it?
An MCP server helps run agentic AI workflows, background jobs, and automations reliably. It allows your AI SaaS to handle complex tasks like video processing, scheduling, and multi-platform uploads in a scalable way.
Will this be production-ready or just a demo?
This is production-ready code, not a demo. I use clean architecture, proper API structure, Docker, CI/CD pipelines, and cloud storage so your SaaS can scale and be maintained long-term.
Can you integrate AI models like OpenAI or other APIs?
Yes. I can integrate AI using MCP servers and connect models like OpenAI or other APIs for automation, content generation, and agent-based workflows.
Do you handle deployment and cloud setup?
Yes. I can deploy your SaaS on cloud infrastructure, set up AWS S3, Docker containers, CI/CD pipelines, and ensure everything runs smoothly.
Can you add more features later?
Absolutely. The system is built to be modular and scalable, so new AI agents, platforms, or features can be added easily.
Should I message you before placing an order?
Yes, please. Messaging first helps us align on scope, timelines, and the best package for your needs.
