Distributed systems, edge-computing platforms, robotics fleets, and real-time financial applications that find Apache Kafka too heavy or complex to operate at the edge frequently search to hire a freelance NATS JetStream, EMQX MQTT & Go messaging programmer. I am Aldian Fazrihady, a Senior Freelance Golang & Distributed Systems Programmer available via Upwork.
Core NATS JetStream & High-Scale MQTT Capabilities
- Global NATS Superclusters & Leaf Nodes: Architecting multi-region NATS JetStream clusters with persistent streams, Key-Value (`KV`) and Object Store buckets, wildcards (`telemetry.region.*.device.>`), and exactly-once deduplication headers.
- Million-Connection EMQX / Mosquitto MQTT Brokers: Terminating TLS/mTLS MQTT 5.0 connections from hundreds of thousands of IoT devices and mobile clients with custom Go/Python auth hooks.
- Sub-Millisecond Microservice RPC: Replacing brittle HTTP service meshes with location-transparent NATS Request-Reply and queue groups.
Frequently Asked Questions
Why choose NATS JetStream over Kafka for Go microservices and edge IoT?
NATS is a single ~20MB Go binary with zero JVM overhead, supports millions of wildcard subjects natively, and allows edge leaf nodes to buffer messages locally during WAN disconnects and sync automatically upon reconnection.
