How I designed an IoT system for smallholder farmers — soil sensors, weather alerts, automated irrigation, and a mobile dashboard using ESP32, MQTT, and Python.

MicroPython makes IoT firmware development faster and more readable. How to collect sensor readings on an ESP32 and publish them to MQTT and a REST API backend.

Step-by-step guide to building a real-time sensor network using Raspberry Pi as gateway, Mosquitto as MQTT broker, and Python to store and visualise sensor data.

There are easier paths in software than building systems for healthcare, agriculture, and education in contexts with real constraints. Here is why I choose this work.

After building projects across healthcare, agriculture, education, e-commerce, DevOps, and IoT, certain lessons come up again and again. Here are the ones that stuck.

AI is changing software engineering. Not replacing it — changing it. Here is what the shift looks like from the perspective of an engineer building AI-integrated systems.

From hospital queue management to real-time patient monitoring with IoT sensors, software is fundamentally changing how healthcare is delivered. Here is what I have learned building healthcare systems.

A practical guide to IoT system architecture — from selecting sensors and microcontrollers to MQTT brokers, edge processing, time-series databases, and real-time dashboards.
