I'm Trying to Get Better at Everything (and Accidentally Building another IoT Network at the same time) I don’t really know where I’m going in tech yet — and for a while, that bothered me. There are so many different paths: backend engineering, embedded systems , web development, networking… and it feels like everyone else has already picked a lane.  I’m trying to see that as a strength rather than a weakness. Instead of specialising too early, I’ve been focusing on getting better at as many areas as I can. Not in a scattered way, but by building things, testing them and testing myself as I go. One of the best examples of that mindset has been my recent dive into IoT . How I've Ended Up Building another IoT System Someone told me about their business idea and it involves IOT which was a big part of my course at Hallam University so I told him that I'm probably the ideal person to build him a prototype IoT system that he can present to his potential funders.  He knows more ...

What My RiverProject is about and Why Sensor Data + MQTT is Revolutionising Environmental Monitoring  💻📶📡📠📉📊📈💹 River Project Repository My  RiverProject , hosted on GitHub, is an ambitious and practical environmental sensing system I built as part of my Year 2 project at Sheffield Hallam University. The core of the project involves collecting real-world sensor data - from a Sense HAT attached to a Raspberry Pi processing that data, and sending it in JSON format via the lightweight messaging protocol MQTT so it can be visualised and analysed elsewhere. GitHub At its heart, RiverProject exemplifies a modern approach to environmental monitoring: shifting away from manual data collection and towards continuous, automated remote sensing . In my project I gather environmental data, create rolling averages, and publish that information through MQTT to other platforms for dashboard visualisation - which can be invaluable for spotting trends or triggering alerts. GitHub Why...

  What is Embedded Systems and why am I into it? 📠📟📞📥📤📬📫📰📲📱📴📳💾💽💻💹 Embedded systems are the quiet workhorses of modern technology. They are specialized computers built into larger products to perform specific tasks, often with strict requirements around timing, reliability, and power consumption. Unlike general-purpose computers such as laptops or smartphones, embedded systems usually run a single application and are designed to do it extremely well. From washing machines and microwave ovens to cars, medical devices, and industrial robots, embedded systems are everywhere, even if we rarely notice them. 🚦🚨🚥 The role of an embedded systems engineer is to design, build, and maintain the software—and sometimes the hardware—that makes these systems function. This often means working close to the metal: writing low-level code in languages like C or C++, configuring microcontrollers, and interacting directly with sensors, motors, and communication interfaces. An embedd...
