FindWay is a globally oriented, asynchronous search and data platform designed to collect, index, and surface time-critical user-generated cases involving missing persons, animals, and stolen property across borders. The system operates as a unified data engine with multilingual, region-agnostic data models and cross-border case handling. Built from scratch with Ruby on Rails, scalable media storage using AWS S3, and an architecture optimized for high-volume writes and real-time discovery. The platform is designed to integrate AI-assisted moderation microservices for text and media filtering, operating as independent, scalable components within the system. FindWay is engineered for reliability, data integrity, and operational resilience in high-stress, real-world scenarios, including crisis and wartime conditions.

AI Moderator System
Integrated & ActiveModular AI Content Moderation System for FindWay.
Technical stack and architecture...
Architecture with 8 models: The system is organized into four independent language contours (CIS, Europe, Baltics, West). Each contour uses two separate ML models: a semantic classifier and a specialized model for detecting slang, text distortions, and obfuscation. Hybrid filtering: The final decision is produced by a policy layer based on neural network scoring and deterministic rules. This approach ensures strict classification of content into Approved, Pending Review, and Blocked, without direct reliance on a single model. Dynamic thresholds: Sensitivity thresholds are configured independently for each language contour and can change at runtime depending on textual patterns, special characters, and the degree of input text distortion.
