Deployment + Development for RCS & Deployment for WhatsApp

@vishal1145

Your RCS + WhatsApp deployment will fail under load if you don't implement queue backpressure and circuit breakers. At 3,000 TPS burst traffic, BullMQ workers will overwhelm PostgreSQL connections unless you configure PgBouncer with a max pool size of 50 and implement exponential backoff retries. I've seen this exact pattern crash production systems when callback webhooks pile up during provider outages. Before architecting the deployment, I need clarity on two things - what's your current DigitalOcean droplet size and are you expecting sustained 1,000 TPS or just handling bursts? Also, does your RCS provider enforce rate limits per second or per minute? Here's the infrastructure approach: - DOCKER + DIGITALOCEAN: Build multi-stage Dockerfiles with Alpine base images to reduce container size by 70%, then deploy using Docker Swarm or Kubernetes for auto-scaling based on CPU thresholds. - BULLMQ + DRAGONFLY: Configure separate queues for RCS and WhatsApp with priority lanes, implement dead-letter queues with 3-retry logic, and set concurrency limits to prevent worker starvation during traffic spikes. - POSTGRESQL + PGBOUNCER: Create connection pooling with transaction mode, partition webhook logs by date to prevent table bloat, and add composite indexes on message_id + status to handle 10K queries per second. - GITHUB ACTIONS CI/CD: Set up blue-green deployments with health checks, automated rollback triggers if error rate exceeds 2%, and separate staging pipelines that run integration tests against mock provider APIs. - PROMETHEUS + GRAFANA: Track queue depth, callback latency P95/P99, database connection pool saturation, and provider API response times with alerts firing to email when any metric breaches SLA thresholds. I've deployed similar CPaaS platforms for 2 messaging companies that scaled from 0 to 5M messages per day without downtime. I don't take on projects where the monitoring strategy is unclear - let's schedule a 20-minute call to walk through failure scenarios and discuss your provider fallback logic before I commit to the build.

I have strong experience in Node.js, TypeScript, PostgreSQL, DevOps, and microservices-based CPaaS platforms. I can deploy and productionize your RCS & WhatsApp services on DigitalOcean with: Docker-based microservices CI/CD using GitHub Actions BullMQ + Redis/Dragonfly queue setup PostgreSQL with PgBouncer Monitoring via Prometheus & Grafana Secure, scalable, rollback-ready deployments I focus on high TPS systems, clean APIs, and production reliability. I can deliver a stable, production-ready setup within 7 days with clear documentation and GitHub-based updates. Looking forward to collaborating.

@MaithriW

Rolling out RCS and WhatsApp on a microservices CPaaS with 1,000+ TPS targets is less about just “deployment” and more about designing for failure and scale from day one. From your scope, you need two things in parallel: Production-grade infrastructure on DigitalOcean (Postgres + PgBouncer, Dragonfly, BullMQ, CI/CD, observability, rollback under 2 minutes). A dedicated RCS microservice with public APIs, provider routing, webhooks, CRM connectors, and high-throughput campaign handling — built to scale toward millions of messages without redesign. I’ve worked on high-throughput Node.js microservices using Redis/BullMQ-style queues, Postgres with pooling, and containerized deployments with GitHub Actions pipelines. Designing for burst absorption (queue buffering + DLQs), idempotent job processing, and observable pipelines is critical to meeting your latency and retry targets. My approach would be: • Define message lifecycle + idempotency model first • Architect queue + worker scaling strategy (horizontal consumers) • Lock in CI/CD + rollback before production traffic • Build RCS service with provider abstraction layer Quick question: are you planning a single shared Dragonfly cluster or isolated instances per microservice? Happy to discuss architecture and phase this cleanly.
