Modu System: Field Service App & Web project cover

Project overview

A commissioned development project for Modu System, covering iOS and Android apps, a customer-facing web service, an admin web application, and a responsive corporate website. Modu System operates the service; KEYPLE handled app and web development and app store release. Customers can request home maintenance and on-site services through the app or web by providing a service type, address, issue description, preferred visit date, and photos. The service also supports assignment updates, progress tracking, and work history. The customer web service provides an installation-free entry point. The admin web application manages requests, users, technicians, coupons, and notices, while the corporate website presents company, service, and branch information. The gallery contains the original Korean store images; it does not represent an English-language app interface.

Challenge

Connect customer service requests, technician fieldwork, and administrative operations within one service workflow. The project needed a customer-facing web option for people without the app, role-appropriate access for customers, technicians, and administrators, and a corporate website to explain the company and its services.

Solution

Built the iOS and Android apps with Flutter, including phone verification, self and proxy requests, address and photo attachments, and progress tracking. Approved technicians can access assigned jobs and field records. Built a customer web service for installation-free requests and history, plus a Next.js admin application for requests, users, technicians, coupons, memberships, and notices. The app and operational web interfaces connect to Supabase-backed data, with Firebase Cloud Messaging for mobile push notifications. Created a responsive corporate website with company, service, branch, and department information, linked to the customer-facing web service.

Result

Released the Modu System app on both the App Store and Google Play. Delivered the customer web service, admin web application, and corporate website alongside the mobile apps, covering service discovery, requests, fieldwork, and operations. Public links lead to the client service and store listings; private admin screens and customer information are excluded from this portfolio.
