In this Portuguese‑language video Samuel Rizon presents his church‑management SaaS, Ministrali, and demonstrates how he built a full‑featured product with a minimal, front‑end‑centric stack and low monthly costs. He walks through the user‑facing features (volunteer scheduling with conflict detection, automatic roster generation, WhatsApp notifications, child check‑in/out, room/calendar management, cell/group maps, member management) and then details the technical architecture: a Framer landing page using Leadster for lead capture and TalkTo for live chat; an Angular front‑end (web and Electron desktop) hosted on Firebase Hosting; a lightweight Render API for Stripe payments and WebSocket printing; and Supabase (Database, Storage, Realtime, Edge Functions) as the primary backend‑as‑a‑service. He explains how Supabase handles authentication, row‑level security, file storage, real‑time event streams, and scheduled Edge Functions that send WhatsApp reminders via ZAPI. Operational metrics are shared (over 2 000 active users, tens of thousands of requests per week) along with cost breakdowns (Supabase ~$25/month, ZAPI ~R$100/month) and current MRR of R$1 949. Samuel emphasizes the feasibility of building a SaaS incrementally, solo, using these tools, and encourages viewers to follow his step‑by‑step playlist.
