Saya sudah memiliki sebuah website aktif, namun beberapa fiturnya belum berjalan sebagaimana mestinya. Fokus utama saya adalah pengembangan web untuk meningkatkan fungsionalitas—mulai dari perbaikan bug yang mengganggu alur pengguna, optimalisasi kecepatan halaman, hingga penambahan elemen interaktif yang lebih modern. Gambaran singkat kebutuhan: • Audit singkat kode front-end dan back-end yang ada. • Identifikasi serta perbaiki titik lemah performa dan keamanan. • Implementasi fitur baru yang dapat meningkatkan pengalaman pengguna (mis. form dinamis, modul pembayaran, atau dashboard sederhana). • Uji fungsionalitas di berbagai browser dan perangkat, lalu dokumentasikan perubahan secara ringkas. Saya terbuka terhadap stack apa pun selama hasilnya stabil dan mudah dirawat. Sertakan portofolio proyek serupa dan perkiraan waktu yang Anda butuhkan untuk tiap tahapan.

Halo, memperbaiki fungsionalitas website yang sudah aktif - bug, performa, keamanan, plus fitur baru - adalah pekerjaan inti saya sebagai full-stack developer. (Saya bekerja dalam bahasa Inggris, tapi bisa mengerjakan langsung dari brief dan kebutuhan Anda.) My approach, in the order that protects a live site: first a short front-end and back-end code audit to find the bugs breaking the user flow, plus the real performance and security weak points (not guesses). Then fixes - the disruptive bugs first - followed by speed optimisation (queries, caching, image/asset loading) and security hardening. After that the new interactive features you mentioned: dynamic forms, a payment module, or a simple dashboard, built to match your existing stack so it stays stable and easy to maintain. Finally, cross-browser and device testing, and concise documentation of every change so nothing is a black box. Two questions so I can estimate each stage accurately: which PHP stack and database is the site on (Laravel, CodeIgniter, custom)? And for the payment module - which provider (Midtrans, Stripe, Xendit) and what flow do you need (checkout, webhook status, transaction history)? Happy to share similar bug-fix/optimisation work. Terima kasih - Zahidul
