Mobile Developer

& Fullstack Developer Enthusiast

In this Laravel-based web platform project for the Information Technology Department at Politeknik Negeri Malang, I was entrusted with designing and developing the entire backend architecture. My role involved creating a robust system for student achievement tracking, featuring a multi-role verification workflow and secure access control. A key highlight of my contribution was the implementation of the PROMETHEE method for an automated competition recommendation system. I took great care in ensuring the mathematical logic of the algorithm was accurately translated into code to provide objective and reliable data insights. Additionally, I developed comprehensive admin dashboards with data visualization and export functionalities to help the department monitor and manage student achievements more effectively, bridging the gap between complex data processing and user-friendly management tools.

Melalui pengembangan aplikasi Absensi berbasis Flutter ini, saya berfokus pada solusi keamanan autentikasi biometrik yang lebih aman dan akurat. Saya mendapatkan pengalaman mendalam dalam mengintegrasikan Google ML Kit dan TFLite untuk pengenalan wajah secara real-time, serta membangun fitur liveness detection untuk mencegah manipulasi sistem. Selain aspek teknis biometrik, saya juga menaruh perhatian besar pada integritas data dengan mengimplementasikan validasi lokasi dan deteksi fake GPS yang terhubung ke backend Laravel. Dalam proses pengembangannya, saya memilih menggunakan BLoC sebagai state management agar alur data aplikasi tetap terstruktur dan responsif. Bagi saya, proyek ini bukan sekadar alat pencatat kehadiran, melainkan upaya saya untuk menghadirkan teknologi mobile yang mengedepankan keamanan tanpa mengorbankan kenyamanan bagi pengguna.

I played a key role in engineering 2 production-grade Flutter applications-Serlok Mitra and Serlok Customer. I successfully translated complex designs into 33+ responsive screens and ensured seamless data flow by integrating REST APIs across core workflows, including identity verification (KYC). My contribution centered on developing the digital wallet system for both apps, managing secure payment flows and real-time balance tracking. By strictly adhering to Clean Architecture and leveraging BLoC for state management, I maintained high performance and robust error handling across 16+ production-ready components. This role allowed me to demonstrate my ability to handle large-scale mobile projects and deliver reliable, user-centric solutions.

As the Team Lead for the Tomalyze project, I headed the development of a Computer Vision system for tomato ripeness classification. Beyond project management, I took the initiative to conduct initial R&D by personally testing image preprocessing and feature extraction techniques before delegating tasks to my team members. This ensured a fair and technically sound workload distribution, as I provided pre-validated workflows for the KNN and SVM algorithm implementations. I was responsible for coordinating the integration of core ML models with Firebase authentication and ensuring a seamless user experience. This leadership role allowed me to demonstrate my ability to guide a technical team while maintaining a 'hands-on' approach to complex problem-solving and system architecture.
