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. ![Yehuda logo](data:image/webp;base64,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) 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. ![Yehuda product interface](/assets/yehuda-diamond-D081O6j_.webp) ### Cross-Platform Mobile App React Native (iOS + Android) with real-time Bluetooth/USB device pairing, red-filter image processing, AI analysis display, firmware OTA updates, warranty management, and offline-first architecture. ### Web Portal & Dashboard React + TypeScript + Material UI with real-time sync, admin dashboard, device lifecycle management, test results gallery and export, plus bulk operations and reporting. ### Cloud Backend & Infrastructure Node.js + Express backend on AWS with MongoDB and S3 storage — AI analysis trigger pipeline, subscription lifecycle and billing, multi-tier payment processing, and automated notifications. ### Hardware Integration & DevOps Deep integration across 5 device families with firmware OTA delivery, Bluetooth & USB protocols, staging-to-production pipelines, and coordinated multi-layer releases. Technology ## Technology stack Production-grade stack chosen for cross-platform reach, global scale, and long-term maintainability. ### Mobile React Native (iOS + Android) — one codebase, native device APIs, Bluetooth and USB device pairing. ### Web Portal React + TypeScript + Material UI — typed, component-driven admin and customer dashboards. ### Backend Node.js + Express — REST APIs, AI orchestration, subscriptions, and notifications. ### Database & Storage MongoDB for application data, AWS S3 for image and report storage. ### Infrastructure AWS EC2, Firebase, and Stripe payments — global deployment with multi-tier billing. ### AI Pipeline Image analysis with confidence metrics, triggered from mobile and processed in the cloud at scale. Results ## Operating at production scale Live platform metrics showing enterprise-grade usage and sustained growth across 3+ years. 188,544 ### Operations performed monthly AI-powered diamond tests running through the platform every month. 2,200+ ### Active subscriptions Paid subscriptions across multi-tier plans, sustained customer growth. 2,270 ### Active users monthly Jewelers and gemologists using the platform across the globe. 540 ### Peak daily users Concurrent weekday peaks served reliably on production. 439 ### Average daily active users Consistent daily engagement across time zones. 65K+ ### All-time bulk downloads Test results and reports exported by customers worldwide. 5 ### Device families integrated Watson AI, Sherlock AI, Dr. Watson, Sherlock Holmes 4, Big Sherlock. 60+ ### Countries with customers Global reach across dozens of countries. Why Mejix ## Why Yehuda partnered with Mejix 01 ### End-to-End Ownership Mejix took the project from zero to production — mobile, web, backend, hardware integration, and DevOps. One partner, complete accountability. 02 ### Lean & Efficient ~3.5 FTE delivering a multi-platform, hardware-integrated product with payments, subscriptions, and AI. Maximum value per dollar spent. 03 ### Continuity & Product Knowledge Same core team since 2022. Deep understanding of hardware constraints, payment flows, device lifecycle, and user behavior. No ramp-up overhead. 04 ### Global Scale Ready Infrastructure built to handle millions of operations, customers across dozens of countries, 24/7 uptime, and coordinated multi-layer deployments. What's next ## Platform impact Five device families integrated, three platforms shipping (iOS, Android, Web), and customers across 60+ countries — all maintained by the same core team since 2022. Production quality assurance with smoke-test checklists before every release, UAT with the client, and coordinated multi-layer deployments across mobile, backend, firmware, and AI services keep 188K+ monthly operations running reliably.
