Geolocation-based Advertisement/Offers
It's an Android/Flutter-based app that was developed to track the user's geolocation and would allow the system to track the geofences and push over offers depending on their nearest trade partner.
This helped the client send over targeted ads/offers to users with greater outcomes.
if you are near a coffee shop that has a partnership with the client, they will detect your location and will send over offers that are available in that coffee shop.

Farm Vehicle Tracking System
It's an Android/Flutter-based app that was created to detect a phone's location in a periodic manner and would send it over to the cloud using MQTT with high throughput and availability,
It was made to be fail-safe. Even if the internet is gone or the phone is off, it will resume without issues.
A dashboard was made where these data would be displayed as if it was a real-time video, using the data points coming in the geocoordinates paths that were plotted on the screen to get a real-time experience.

Remote Solar Monitoring System
The system was to enable the 30-year-old solar inverter, which was communicating with a sitting computer with standalone software running on it using very old tech. The client wanted to put it on the cloud but had no documentation about it as it was quite old.
I used Raspberry Pi, which would connect to those devices using rs42 to a Modbus connector, and then I tracked the incoming packets using Wireshark and then decoded what was sent to the old computer.
Using Node.js and Python code on Raspberry Pi, I was able to communicate with the device, and I used MQTT and Restful APIs to send the data to the server.
Grafana was used to convert the real-time data into dashboards and allowed a visual representation of the data. Telegraf was also used to convert raw data into the desired format.

Smart Water Heater System
The system was built around a water heater which has no digital output except the LED lights showing the status of the motor, water level, and temperature.
So, I built a custom circuit that would convert those LED (AC) signals and converted it into digital ones using AC/DC converters. Then, using that value, I connected those signals to Raspberry Pi. The signals would then send data to the server using MQTT using a Wifi dongle. This enabled the client to detect if there was any anomaly in the heater at any time.
