I’m ready to launch a cloud-based bulk WhatsApp service from my shared Linux server and need an experienced developer who can install and configure the full platform for me to resell campaigns. Core capabilities I must have from day one: • Message scheduling so I can queue broadcasts in advance. • Robust contact management, with the option to upload large recipient lists via CSV. • Detailed analytics and reporting dashboards to track delivery, opens, and engagement. • Dynamic field support (names, dates, custom tags) so each message feels personal. The environment is a standard shared Linux host. Whatever stack you choose—Node.js, PHP, Python, MySQL, MongoDB—just ensure it runs smoothly within typical cPanel constraints and stays compliant with WhatsApp’s policies. After installation I should be able to log in, import a CSV, build campaigns, preview personalized messages, schedule the send, and later download or view the analytics. Please include: 1. A working, browser-based admin panel and user panel ready for white-label branding. 2. Step-by-step deployment notes or a script so I can replicate the setup if I migrate servers. 3. Basic hardening (SSL setup, IP rate limits, queue handling) to keep the account safe. 4. A quick hand-off session or concise documentation covering day-to-day use. If you have prior experience getting WhatsApp Business API or similar bulk messaging tools running on shared hosts, that’s a big plus—feel free to share a link or screenshot. I’m looking to move quickly, so let me know your estimated timeframe from access credentials to first successful test blast.
