The Problem
A spiritual content brand needed a complete digital ecosystem that could generate and publish content autonomously in 3 languages, produce video across YouTube/TikTok/Facebook/Pinterest, capture and nurture leads through multiple touchpoints, and operate with near-zero hosting costs — all without scaling team size.
How It Works
01
Trend Detection
Google Trends + News RSS feeds from US/MX/BR filtered by DeepSeek AI for relevance.
02
AI Content Generation
DeepSeek writes articles, scripts, and social posts in 3 languages natively (not translated).
03
Video Production
Custom Remotion engine renders videos with AI voiceover (Google TTS), AI images (GPT Image), and animated templates.
04
Multi-Platform Publishing
Automated distribution to YouTube, TikTok, Facebook Reels, Pinterest, and X.
05
Email Marketing
Weekly horoscopes (36 lists), drip campaigns, quiz funnels — all trilingual via Listmonk + Mautic.
06
AI Chat Agent
Chatwoot-powered bilingual agent that captures leads, scores them in Mautic, and upsells.

Engineering Challenges Solved
🎬 Video Duration Synchronization
Videos must match voiceover audio length exactly. Different languages produce different audio durations for the same script.
Solution: Remotion's calculateMetadata measures MP3 duration and distributes scene timing proportionally. Each language version gets perfect sync.
🌐 Multilingual TTS Optimization
TTS engines don't handle pauses naturally. Rapid-fire speech without breathing room sounds robotic.
Solution: SSML <break> tags with strategic timing (400-900ms) optimized by AI "Script Expert" per language. Scripts are written natively, not translated.
🖼️ Image Asset Reuse Across Languages
Generating unique images per language triples cost. 5 images × 3 languages = 15 generations per topic.
Solution: Generate once, store in tagged PostgreSQL image library, reuse across all 3 language versions. 5 images serve 3 videos = 67% cost reduction.
📌 JavaScript Precision Loss with Pinterest
Pinterest Board IDs exceed Number.MAX_SAFE_INTEGER (>1018). Dynamic computation silently produces wrong IDs.
Solution: Static string mapping instead of dynamic JS computation. Discovered this edge case after hours of debugging "wrong board" errors.
💡 These patterns are reusable for any multilingual content automation project — from video production to social media distribution at scale.
