What is LawMate App

LawMate is a mobile application developed as part of the Bangkit Academy Capstone Project, which successfully placed our team in the Top 50 Projects of Bangkit Academy 2023.

The application addresses the critical issue of sexual violence, where many victims are often afraid or reluctant to share their stories. Through LawMate, users can interact with an AI-powered chat assistant that helps detect signs of sexual harassment and recommends qualified lawyers to provide proper legal assistance.

Team Collaboration

• Machine Learning — developed an AI model to detect patterns of sexual violence in conversations.
• Cloud Computing — managed servers, APIs, and cloud infrastructure to support scalability.
• Mobile Development — built the Android application to bring the solution directly to users.

My Role — Android Developer

As the Mobile Developer, I was responsible for building the Android application using Kotlin and the MVVM architecture. My tasks included:

• Designing and implementing the User Interface (UI) with XML layouts to ensure a clean and user-friendly experience.
• Integrating REST APIs for communication between the mobile app and backend services.
• Implementing LottieFiles animations to enhance user engagement with modern interactive visuals.
• Applying clean architecture principles to ensure scalability, maintainability, and testability.

My Development Workflow

1. Requirement Analysis — collaborated with the team to gather user needs and define features.
2. UI/UX Design — designed wireframes and XML-based layouts for a seamless user experience.
3. API Integration — connected the app with backend services using Retrofit for REST API calls.
4. Feature Implementation — added AI-chat interaction, lawyer recommendation system, and user authentication.
5. Enhancement — integrated Lottie animations and improved performance with MVVM + LiveData.
6. Testing & Deployment — performed functional testing and deployed the app for final evaluation.

Impact

LawMate represents an innovative solution with a meaningful social impact, providing victims of sexual violence with a safe platform to seek help. The project not only showcased our technical expertise across multiple disciplines but also received recognition as one of the Top 50 Bangkit Capstone Projects.

What is Delapan Jaya Farm App

Delapan Jaya Farm is an Android-based monitoring application I designed to address challenges in managing beef cattle farms. The main problem faced by farm owners was the difficulty of monitoring partner activities, including feed distribution, cattle health status, and feed ordering activities.

Background & Objectives

The primary goal of this project was to build an Android monitoring system that enables farm owners to:

• Track livestock feeding status in real time.
• Identify if any cattle are sick and take immediate action.
• Monitor and record feed ordering activities by partners.

Development

As the Android Developer, I was fully responsible for designing, implementing, and optimizing the application. My contributions included:

• Building the User Interface (UI) with Jetpack Compose to deliver a modern, dynamic, and intuitive user experience.
• Implementing Firebase as the main backend service for authentication, real-time data storage, and synchronization.
• Integrating WorkManager to handle automated notifications, ensuring owners and partners stay updated even when the app is not active.
• Applying the MVVM (Model-View-ViewModel) architecture to keep the codebase structured, scalable, and maintainable.

My Development Workflow

1. Requirement Analysis — identified farm management problems and defined app features with stakeholders.
2. UI Design — created Jetpack Compose prototypes for responsive and clean layouts.
3. Backend Integration — connected the app with Firebase for real-time synchronization and authentication.
4. Feature Implementation — added feeding schedule tracking, health monitoring, and feed ordering modules.
5. Notifications — implemented WorkManager to push alerts for feeding updates and health issues.
6. Testing & Optimization — ensured smooth performance, usability, and stability before deployment.

Results & Impact

With Delapan Jaya Farm, farm owners can now monitor livestock operations more effectively and efficiently. The system improves transparency of partner activities, speeds up responses to health issues, and ensures feed supply management runs smoothly.

This project not only delivered a practical solution but also served as an example of how mobile technology can drive digital transformation in the agricultural sector.

What is Donora?

DONORA is an Android application built to help users locate the nearest blood donation centers. The app leverages Google Maps API and the device’s GPS to provide accurate location-based results.

Key Features

• Locate nearby blood donation centers with Google Maps integration.
• Display directions from the user’s current GPS location.
• Provide details such as center name, address, and contact information.
• Enable smooth navigation and map interaction.

Development

In this project I was responsible for the design and implementation of the app. I used XML for interface design and integrated Google Maps API to connect GPS with location services. The application was built with focus on usability and efficient performance.

• Designed layouts with XML to ensure responsive views.
• Connected the Maps SDK for Android to fetch and display locations.
• Implemented GPS-based tracking to identify user location in real time.
• Tested across different devices to confirm reliability.

Workflow

1. Requirement Analysis — identified the need for a platform to simplify blood donation location search.
2. UI Design — created XML layouts for clarity and ease of navigation.
3. Integration — connected Maps API and GPS features.
4. Implementation — added functions for location detection and directions.
5. Testing — ensured app stability and smooth map interaction.

Impact

DONORA improves access to blood donation centers by reducing the time and effort needed to find the nearest location. This project demonstrates how mobile technology can support public health services through simple but effective tools.

What is Movie App

Movie App is a mobile application built with React Native as part of the Final Project in the Digitalent x Progate program. This project was developed in a team of two people, and I was mainly responsible for creating four core pages of the application.

Project Features

• Home Page: Displays movies that are now playing, upcoming movies, top-rated movies, and popular movies.
• Search Page: Allows users to search movies by keyword or category (genre) using data from TMDb API.
• Movie Detail Page: Shows detailed movie information such as rating, language, release date, popularity, and also provides movie recommendations.
• Favorite Page: Lets users save their favorite movies locally using AsyncStorage, so the data remains available even after closing the app.

Development Stages

1. Project Setup: Initialized the React Native project, configured environment, and installed required dependencies.
2. API Integration: Connected the app to TMDb API to fetch real-time movie data (listings, details, and categories).
3. UI/UX Implementation: Designed and developed user interfaces for 4 pages with a focus on clean layout and intuitive navigation.
4. State Management & Local Storage: Implemented AsyncStorage to persist favorite movies chosen by the user.
5. Testing & Debugging: Performed functionality testing on Android devices to ensure stability and smooth user experience.
6. Version Control: Used Git and GitHub for collaboration, branch management, and project tracking with my teammate.

My Contributions

• Developed and implemented Home, Search, Movie Detail, and Favorite pages.
• Integrated TMDb API to retrieve movie data and implemented search functionality.
• Created local storage system using AsyncStorage to save user’s favorite movies.
• Designed a responsive and user-friendly UI with proper navigation flow.
• Collaborated with my teammate via GitHub, including pull requests, code reviews, and resolving conflicts.

Technologies Used

• React Native (Frontend Development)
• TMDb API (Movie Data Source)
• AsyncStorage (Local Data Storage)
• Git & GitHub (Version Control & Team Collaboration)

This project provided me with valuable hands-on experience in API integration, mobile UI development, state management, and teamwork. It also strengthened my skills in building mobile applications that combine clean design with real-time data and persistent local storage.
