The Problem

Global geopolitical and tech news cycles move too fast for manual monitoring, creating a massive noise-to-signal ratio.

The Approach

A high-density analytical terminal that distills vast world-event feeds into real-time summaries and severity scores via multi-provider AI failover.

Impact Highlights

  • Reduced AI inference costs to near-zero with a multi-tier local pipeline (Mac M1 LlamaCPP → VPS local → Groq → OpenRouter) and automatic fallback chaining.
  • Automated content distribution via SignalStack Pulse — Twitter/X, Facebook, LinkedIn OAuth, platform-aware content transformer, and rate limiting (2 posts/day cap on X).
  • Solved geolocation-based company discovery with Company Radar — OSM/Overpass, Mapbox, Google Places, e-CAB, and GitHub tech sources with smart career page detection.
  • Made the platform accessible in Bengali via a Redis-backed translation priority queue with dual-tier quality threshold.
  • Centralised job market intelligence by aggregating remote sources into a unified feed with Discord alerts, dedup, and global remote filter.
