Masnaek is a full industrial-services mobile application that I developed using Android Native (Kotlin).
The app simulates a complete industrial city with five different user roles, each having its own workflow, permissions, and interface.

This project demonstrates my ability to build complex mobile architectures, role-based systems, real-time operations, and service-driven workflows inside a single ecosystem.

What I Built

✔ Full Android Native App (Kotlin)

Designed and developed the app entirely using Kotlin, Material Design, ViewModels, LiveData, Room (optional), Retrofit, and MVVM architecture.

✔ 5 Independent User Roles

I built a multi-role system inside a single mobile application:

1. Merchant

2. Factory

3. Technician

4. Driver

5. End Customer

Each role has:

• its own dashboard

• its own workflow

• specific permissions

• different UI interactions

• dedicated screens and API calls

✔ Industrial Workflow Engine

The app handles real manufacturing/service cycles:

Request → Quote → Accept → Assign (Technician + Driver) → Execution → Delivery → Completion

Supported by:

• state machine rules

• validation

• progress tracking

• notifications

✔ Integrated Service Sectors

Built full support for multiple manufacturing industries:

• Iron

• Glass

• Wood

• Aluminum

• Accessories

Each industry has:

• Categories

• Sub-services

• Attachments

• Notes

• Extra options

✔ Real-Time Notifications

Using Firebase Cloud Messaging (FCM):

• New requests

• Status updates

• Assignment updates

• Driver arrival

• Technician acceptance

• Completion notifications

✔ Advanced UI & Loaders

Implemented:

• Custom animated loaders

• Smooth transitions

• Bottom sheets

• Dialog interactions

• Dynamic content rendering

✔ API Integration

Connected to a Laravel backend via Retrofit + JWT authentication, with:

• structured models

• caching strategy

• error handling

• retries for unstable connections

✔ WebView for Additional Dynamic Content

Used WebView for:

• policies

• dynamic pages

• documentation

• some info screens that update without app updates

✔ Driver & Technician Features

• Live location reading

• Directions

• Accept/reject jobs

• Uploading images before & after

• Task timelines

✔ End Customer Flow

• Submit request

• Select industry

• Add photos

• Track request progress

• Receive quotes

• Assign preferred technician or factory

Challenges I Solved

• Designing multi-role UX without confusing the user

• Maintaining clean architecture with 5 role-based flows

• Optimizing background tasks and network requests

• Handling large numbers of state transitions

• Ensuring fast performance despite complexity

• Building push notification logic for each role separately

What This Project Demonstrates About My Skills

• Strong experience in Android Native development

• Designing complex workflows for real operations

• Clean, scalable mobile architecture (MVVM)

• Role-management and permission-based UX

• Connectivity, APIs, background jobs, notifications

• Building apps ready for real industrial environments
