Saya membutuhkan seorang developer untuk membangun aplikasi pengumpulan data pelanggan yang andal dan mudah diperluas. Fokus utama proyek ini adalah: • Mengumpulkan dan menyimpan informasi pelanggan secara terstruktur (nama, kontak, riwayat interaksi, dan preferensi). • Menyediakan antarmuka web yang intuitif agar staf non-teknis bisa memasukkan, mencari, dan mengekspor data dengan cepat. • Memastikan keamanan data melalui autentikasi pengguna dan enkripsi dasar saat transit maupun saat tersimpan. Teknis yang saya bayangkan: – Backend dapat ditulis dengan framework modern seperti Laravel, Node.js, atau Django—silakan pilih yang paling Anda kuasai. – Database relasional (MySQL atau PostgreSQL) dengan skema rapi dan relasi jelas. – Frontend sederhana berbasis React, Vue, atau templating bawaan framework, selama responsif di desktop dan mobile. – Dokumentasi singkat cara instalasi lokal dan cara deploy ke VPS/Linux. Ruang lingkup awal hanya data pelanggan, tetapi ke depan sistem mungkin diperluas untuk data inventaris maupun data keuangan, jadi struktur kode dan database perlu dirancang modular. Kirimkan: 1. Rencana teknis singkat beserta stack pilihan. 2. Perkiraan durasi pengerjaan tahap MVP. 3. Contoh proyek serupa yang pernah Anda kerjakan. Saya menghargai kode bersih, commit git teratur, dan komunikasi proaktif. Terima kasih!

Hello, thanks for posting this project. Your requirements align closely with my expertise in building modular and secure web applications. My primary focus would be to design a robust database schema for customer data, implement a user-friendly interface tailored for non-technical staff, and ensure data security via authentication and encryption in both transit and storage. I am comfortable working with Node.js (Express) for the backend and PostgreSQL for the database, paired with a responsive React-based frontend. The system's architecture will be modular, making future extensions to inventory or finance data seamless. I will also provide concise installation and deployment documentation. Could you share if you have any preference for cloud hosting providers or if certain compliance standards (such as GDPR) should be considered for data storage?
