JS Duke Accelerates Ministry Outreach with a Multi-Tenant AI Chatbot

Overview

JS Duke, LLC helps congregations embrace modern tools. They envisioned a multi-tenant SaaS platform that lets any church embed an AI-powered chatbot in minutes zero infrastructure. With the Church Leadership Conference, they asked D3V to architect, build, and launch the MVP on Google Cloud before the event.

The Challenge

• Tight deadline – MVP had to be production-ready in 5 weeks to demo at the conference.
• No in-house engineering – JS Duke relied entirely on D3V Technology Solutions for cloud, DevOps, and AI.
• Data scarcity – No existing chatbot training data; the platform had to perform well with small FAQ uploads & existing website links/documents.
• Multi-tenant architecture – Each church required strict data isolation.

Our Solution

• Cloud Foundations
  • Provisioned a dedicated GCP project with least-privilege IAM, VPC-SC, and billing alerts.
  • Set up Cloud Build-driven CI/CD and blue-green deployments on Cloud Run (frontend + backend).
• AI Core
  • Integrated Vertex AI LLM with reusable prompt templates and a Weaviate vector DB for church-specific FAQs.
• Web Portal & Widget
  • Built a Next.js Church Admin Console: onboarding wizard, prompt editor, and file uploader (PDF, CSV, Docs).
  • Delivered a one < script > snippet that drops a chat widget onto any CMS or website.
• Quality & Security
  • Load-tested to 500 concurrent chats per tenant with < 200 ms P95 latency.
  • Passed static/dynamic security scans zero critical findings.
• Pilot & Handoff
  • Deployed to two beta congregations, captured live feedback, and tuned intents.
  • Cost estimates

Impact

• Instant answers: Visitor response times dropped from 18 hours to real-time 24/7.
• Staff efficiency: Pastoral teams reclaimed 7–9 hours per week previously spent on Q&A.
• Friction-free onboarding: New churches go live in under 10-20 minutes with no IT help.
• Cost control: Serverless Cloud Run scales to 0, cutting idle spend while meeting peak demand.
• Conference splash: Live demo at the April 25 conference secured 15 pilot sign-ups in two days.

Key Accomplishments

• 30-Day MVP Delivery: From blank sheet to conference-ready product on schedule and within fixed budget.
• Multi-Tenant Isolation: Per-church namespaces, keys, and usage dashboards safeguard data and privacy.
• Dev Velocity: Automated CI/CD enables safe, click-free releases; traffic-splitting supports canary rollouts.
• Scalability & Portability: Containerized services run on Cloud Run today and can shift to any K8s platform tomorrow.
