Although this kit is self-service, I help ambitious founders move faster.
I can help you with:

• Managed Config: I sets up your AWS/GCP production environment so you never touch DevOps.
• Custom Features: Need SAML SSO or complex RAG flows? I'll build them directly into your repo.
• Code Audits: Migrating from Node/Python? I'll review your architecture for scale.
