RCS Marketing Messaging Platform

@mahig47

Hello! As per your project post, you’re looking to build a high-performance RCS marketing messaging platform capable of enterprise-scale messaging, with APIs, webhooks, and queue-based delivery pipelines. The goal is to extend your existing service while supporting seamless integration, high throughput, and reliable message delivery for campaigns, templates, and reporting. My focus will be on delivering a robust backend with scalable queue architecture, stateless APIs, and flexible integration connectors for CRMs such as MoEngage, Webengage, and CleverTap. The solution will include durable queues, idempotent retry logic, horizontal scaling capabilities, and real-time monitoring metrics to ensure performance and reliability targets are met. The architecture will allow easy addition of new integrations and ensure SLA compliance for enqueue, dequeue, and delivery pipelines. I specialize in designing high-throughput messaging systems with resilient API architecture, scalable queue processing, and precise monitoring frameworks. My approach ensures predictable performance under load, fault tolerance, and efficient integration with existing enterprise platforms. Let’s connect to define the queue architecture, SLA priorities, and integration design so we can deliver a scalable, enterprise-ready RCS messaging system. Best regards, Nikita Gupta.

Hello, I understand you need an enterprise-grade CPaaS extension built on top of your existing service, with high-throughput APIs, durable queue processing, webhook handling, and seamless CRM integrations — all pushed to your GitHub repository post-award. I can design and develop stateless, horizontally scalable APIs (PHP/Java/Node.js) capable of sustaining 500–1,000 req/sec with burst handling up to 3,000 TPS using distributed queues (Kafka/RabbitMQ), graceful throttling, and idempotent retry logic to guarantee zero message loss. I will implement: • Public APIs for campaigns, templates & reports • Webhooks for DLRs & inbound replies (<2s callback SLA) • Queue SLA: <200ms enqueue, <1s worker dispatch • Durable persistence with verification & replay safety • Read/write contention mitigation (replicas, indexing, sharding strategy) • Independent auto-scaling workers • Monitoring: TPS, queue lag, throughput, failure alerts For integrations, I’ll architect a connector layer (MoEngage, WebEngage, CleverTap) using adapter patterns to allow plug-and-play future CRMs. I have strong experience in backend architecture, MySQL optimization, cloud deployment, distributed systems, and webhook-driven platforms. One question: do you prefer a specific cloud stack (AWS/GCP/Azure) and queue technology, or should I propose an optimized architecture? Let’s connect to discuss architecture flow and rollout plan. Best regards, Arshiya

Hi, Your RCS Messaging Microservice project fits well with the type of scalable backend systems I build. I have experience developing high-throughput APIs, queue-driven architectures, and messaging platforms that handle large campaign traffic reliably. Based on your requirements, I would extend the existing system by implementing stateless REST APIs (Express + TypeScript) and using BullMQ with Redis/Dragonfly to manage asynchronous campaign processing and burst traffic. This approach allows the service to sustain 500–1000 TPS with burst handling up to 3000 TPS through queue buffering and scalable worker pools. For reliability, I would implement idempotent message processing, provider-aware retry logic, and durable queue persistence to guarantee zero message loss. PostgreSQL schemas would be optimized to minimize read/write contention and support large campaign datasets. The service will include public APIs for campaigns, templates, and reports, along with webhooks for delivery receipts and incoming messages. I would also integrate monitoring for TPS tracking, queue lag, worker throughput, and failure alerts. I’m comfortable working with your stack: Node.js, TypeScript, Express, BullMQ, DragonflyDB, PostgreSQL, and microservice architectures. Happy to discuss message volume expectations and provider routing strategy before starting. Best regards, Thanh

Hi there, I’m excited about the opportunity to build a high-performance CPaaS backend extension that integrates seamlessly with your existing platform. I have experience designing scalable APIs, queue-driven messaging systems, and webhook infrastructures capable of handling high throughput with strict reliability requirements. Proposed stack: Node.js (NestJS) or Go for high-concurrency APIs, PostgreSQL for structured storage with read replicas, Redis for caching, and Kafka or RabbitMQ for durable queue processing. Services will be containerized and designed for horizontal scaling with stateless API layers and independently scalable workers. Approach: 1. Design database schema and queue architecture optimized for high-volume campaign dispatch. 2. Build public APIs for campaign sending, template management, and reporting with rate control and idempotency. 3. Implement webhook pipelines for DLRs and inbound messages with retry-safe processing. 4. Develop a queue system capable of sustaining 500–1,000 TPS and bursts up to 3,000 TPS with graceful buffering and no message loss. 5. Implement monitoring for TPS, queue lag, worker throughput, API latency, and failure alerts. The architecture will support easy CRM integrations (MoEngage, WebEngage, CleverTap) via modular connectors and follow your GitHub repository workflow for all updates. I’d be happy to review the repo and discuss scaling details before starting. Best regards, Pooja
