I’m looking to build a bulk SMS SaaS platform and I’m searching for an experienced developer to work with. Here are the main features I need: • Upload leads via CSV • Send SMS campaigns • Inbox to receive and manage replies • Tags / flags system to organize contacts • Integration with Twilio or Telnyx • User accounts (multi-user SaaS) • Dashboard with campaign stats and activity I also want to mention that I’m looking for someone for a long-term partnership. My goal is to first build the platform and make sure it works 100% perfectly. After that, I will start bringing in clients, and I will need you to continue working with me for maintenance, improvements, and adding new features. Please let me know if you have built something similar before, and if yes, I would love to see examples.
