IoT & Edge Computing
IoT system design, MQTT, edge computing, real time telemetry, EV ecosystems, and getting hardware to talk to software reliably.
Building an IoT Backend for EV Charging Networks
Smart EV charging is not just hardware. You need OCPP protocol handling, device telemetry at scale, and a backend that can take the load. This post goes through the full system design using MQTT, Kafka, and cloud infrastructure.
Building Apps That Work Without Internet Using RxDB
Offline support is easy to promise and hard to ship. This post is based on real work done on an EV fleet management desktop app and covers how RxDB handles local storage, conflict resolution, and syncing data back to the server.
Running MQTT at Scale When You Have Thousands of Devices
A single MQTT broker works fine in testing. Once you have thousands of devices publishing at the same time, things break in ways you did not expect. This post covers clustering, load balancing, and bridging with EMQX and HiveMQ.
Connecting Arduino Sensors to a Cloud Backend That Can Handle the Load
Getting data from a hardware sensor into the cloud sounds simple until you have to deal with firmware communication, protocol bridging, and a backend that needs to process thousands of readings without falling over.
