...the million-plus mark. To stay ahead of that growth I’m restructuring the entire infrastructure and codebase for true horizontal scale, bullet-proof uptime, and lightning performance. Here is the current landscape you’ll step into: • Native iOS & Android codebases that need profiling, refactoring where necessary, and tighter CI/CD. • A Laravel monolith that must be modularised, cached with Redis, and tuned for very high concurrency. • PostgreSQL instances approaching their limits; we’re ready for partitioning, read replicas, and autoscaling. • Alibaba Cloud services (ECS, RDS, OSS, SLB) underpin everything, though I’m open to architectural suggestions, even hybrid or multi-cloud, if they offer measurable benefit. • R...

...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.
