I have a production-ready SaaS built with Python, Django, , HTMX, Postgres, Celery and Redis. The core application already handles user authentication, real-time notifications and a solid analytics dashboard. The next sprint focuses on two major upgrades: • Build an advanced reporting module that lets admins filter, export and schedule reports pulled from our existing analytics pipeline. Think multi-dimension filters, CSV/PDF export and email scheduling, all delivered without page reloads via HTMX. • Integrate the platform with leading CRM systems (starting with HubSpot, then mapping a clean interface for future connectors). This will involve OAuth flows, webhook listeners and background jobs in Celery to keep data in sync. What I need from you • End-...

...bulk-media sender that talks to WhatsApp Business Cloud through a webhook. Whenever the API answers with HTTP 429, the webhook does mark the message as failed, yet the queued retry flow (RetryFailedWhatsAppJob on Redis/cloud queue) rarely fires, and when it does, the image-ID matching logic sometimes mis-aligns. The result is missed retries or, worse, duplicate sends. Here’s what needs to happen: • Repair the webhook callback so the media object returned by WhatsApp is always matched to the correct outbound record. • Ensure the job is dispatched, picked up, and processed on the existing Redis-backed queue every time a 429 occurs, honouring the current attempt counter. • Implement a reliable back-off for those 429 responses so we respect rate li...

At the moment I’m not even sure whether the host is running cPanel, Plesk, or DirectAdmin, so the first step will be to look at the control-panel details with me and confirm the environment.
