I’ve been experimenting with Claude Code a lot recently, and I wanted to push it beyond basic code-gen tasks. So I tried something slightly uncomfortable: build a small personal AI CRM from scratch and let the agent handle not just code, but backend setup and deployment as well. What I’ve realized over the past year is that frontend isn’t the bottleneck anymore (thanks to all the amazing plug-ins, Skills). So tbh, as of now, building UI is quite fast. There are Component libraries that we already use. Coding agents handle most of it pretty well. The place where things slow down is always the backend part. Auth, Database, Permissions, Environment config, and Deployment flow, there are a lot of moving parts. We need to run multiple steps with multiple tools from different mcp servers. That’s where things usually get messy. This time, I stayed inside Claude Code the entire time. I started in plan mode and asked it to design the system properly: schema, relationships, auth model, basic CRUD structure, and how we’d expose it. The plan it generated was actually structured and reasonable. I reviewed it, tweaked a couple of things, and accepted it. Then I let it execute. Through MCP servers, it handled backend provisioning, database setup, auth configuration, permission rules, environment variables, and the deploy step. I wasn’t jumping into dashboards or manually wiring things together. It was all driven from the agent loop. What was interesting wasn’t just that it worked. It was the workflow: Plan first. Review the plan. Approve it Let it build and deploy Check the live link. Everything happened in one continuous Claude Code session. No context switching. No half-finished infra steps. By the end, the CRM was live on a public URL. In conclusion i would like to say it’s not about the CRM itself. It’s more about seeing how far the Claude Code, with the help of MCPs, Skills can go when you use it with the correct tools I recorded the full build process here if anyone wants to see how i did it submitted by /u/Arindam_200
