I’m running a live PHPProBid marketplace and need a developer who already knows this script inside-out. My immediate goals are: • Add a phone field to the registration form and trigger a one-time code via WhatsApp message (no SMS fallback needed). The account must remain inactive until the code is confirmed. • Mirror every existing email notification—registration, offers, bids, invoices, the works—into a matching WhatsApp message so users can choose either channel and never miss an update. • Troubleshoot and repair the current SMTP configuration; right now messages are simply not leaving the server even though credentials test fine. You’ll work directly in the current code-base (latest PHPProBid version) and deliver fully tested fixes on a staging copy before I push them live. Familiarity with WhatsApp Business API, Twilio or similar gateways, PHP, MySQL and the script’s internal mailer class is essential. If you’ve modified PHPProBid before, this should be straightforward. Let me know your approach and estimated turnaround so we can get started right away.
