Arsitektur subsistem dan alur kapabilitas utama yang dibangun pada platform EduVerse.
Real-Time Student Discussion Threads
Sinkronisasi Pesan & Tanya Jawab Realtime
Forum belajar interaktif antar mahasiswa dengan pembaruan data sub-detik menggunakan Cloud Firestore realtime snapshot listeners.
- Sinkronisasi data dua arah instan saat ada pertanyaan atau balasan baru.
- Dukungan formatting teks dan penandaan jawaban terbaik (best answer).
- Penyaringan topik diskusi berdasarkan mata kuliah dan peminatan.
Interactive Quizzes & Live Leaderboard
Evaluasi Pemahaman & Peringkat Belajar
Modul kuis interaktif dengan pewaktu mundur otomatis, penskoran instan, dan papan peringkat kompetitif antar mahasiswa.
- State management kuis reaktif menggunakan StateFlow dan Coroutines.
- Kalkulasi skor otomatis dan update leaderboard berkala.
- Riwayat evaluasi performa akademik pengguna.
Cloud Media Attachment Pipeline
Unggah Gambar & Cuplikan Kode
Pipeline pengunggahan gambar tugas dan screenshot kode ke Imgur API dengan kompresi bitmap sebelum transmisi data.
- Downsampling gambar otomatis di sisi klien untuk mencegah OutOfMemory (OOM) pada perangkat spesifikasi terjangkau.
- Unggah berkas asinkronus menggunakan Kotlin Coroutines.
- Manajemen status upload interaktif dengan progress indicator.
Implementasi Teknis & Rekayasa Sistem
Native Android Architecture (MVVM)
Implemented Model-View-ViewModel architecture with Kotlin Coroutines and StateFlow to maintain clean data flows and lifecycle safety.
- Decoupled UI view rendering from underlying network state and database listeners.
- Leveraged asynchronous Coroutines to ensure smooth 60 FPS scrolling during heavy data parsing.
- Structured modular repository classes facilitating clean testability and maintenance.
Firebase Serverless Backend
Integrated Firebase Authentication and Cloud Firestore for resilient real-time cloud data management without running a custom server.
- Configured secure authentication rules validating user tokens and email domains.
- Implemented Firestore real-time snapshot listeners for live discussion feed updates.
- Structured document collections to balance read/write operations and stay within free tier limits.
Imgur Media Upload Pipeline
Engineered an asynchronous media attachment pipeline allowing users to attach photos and code screenshots to forum posts.
- Implemented client-side bitmap downsampling and compression prior to upload.
- Integrated Imgur API REST endpoints with custom bearer authentication headers.
- Handled network retry logic and upload progress state for unstable mobile connections.
Hasil Kunci & Dampak Operasional
Sub-second bidirectional data synchronization for live discussion threads and quiz leaderboards.
Separated UI components from business logic and data repositories using modern Kotlin Coroutines.
Asynchronous image compression and upload to Imgur API preserving device memory.
Successfully defended and evaluated with top marks in Mobile Application Programming.
