The hardware was capable and precise, but there was no software ecosystem to bring it to life. To scale globally, Yehuda needed a complete platform: cross-platform mobile apps (iOS + Android), a web portal for analytics and account management, a cloud backend to handle AI analysis at scale, and deep hardware integration across multiple device families. The challenge: deliver all of this as an end-to-end platform partner while the client focused on hardware innovation. Image: Yehuda logo What this project delivered A production-ready outcome built for Yehuda — designed for measurable impact across operations. Challenges ## What the platform had to deliver A multi-layer product spanning mobile, web, cloud, hardware, and AI — built and operated by a single partner. Challenge ### Cross-platform mobile app iOS + Android app with Bluetooth and USB device pairing, image capture, AI analysis display, firmware OTA updates, and warranty management. Challenge ### Web portal & dashboard Account management, analytics, admin workflows, device lifecycle, test gallery, and bulk operations for global customers. Challenge ### Cloud backend at scale A global AI analysis pipeline, subscription lifecycle, multi-tier billing, automated notifications, and 24/7 uptime. Challenge ### Hardware integration Deep integration across 5 device families — Bluetooth and USB protocols, firmware OTA delivery, and coordinated multi-layer releases. Challenge ### AI integration Image analysis with confidence metrics, run reliably at production scale across millions of operations. Approach ## How we turned the concept into a working product Mejix adopted a lean, iterative delivery model with one senior specialist per discipline — no bloat, maximum ownership and continuity. The same core team has grown the platform since 2022. Each release is coordinated across mobile, backend, firmware, and AI services with smoke-test checklists and UAT before going live, so a multi-platform product behaves like a single, predictable system. Solutions ## An end-to-end SaaS platform built to commercialize hardware Four tightly integrated systems — mobile, web, cloud, and hardware — designed and operated as one product.
