Started with one belief: a blind person shouldn't need a companion to move through the world. V1 ran on GPS/GSM and taught me web dev, Android, and backend from scratch — but it needed constant connectivity and had no intelligence. V3 rebuilt everything: Raspberry Pi 5, camera-based object detection, haptic feedback, and offline-first communication — no internet required, zero-downtime Kafka notifications on AWS.
V4 (in progress): turn-by-turn navigation, scene description, OCR, and fall detection.
