Social App for Travellers
Orijin Plus
https://www.orijin.plus/Geolocation-based Advertisement/Offers
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 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.
Mobile Wallet for Mobile/Web
https://apps.apple.com/sg/app/carte-bonjour/id742161961FEATURES
• It shows your location and nearby parking spots available.
• Allows you to save your cards and use them when needed.
• Allows you to use the same points at partner outlets and pay for meals, etc.
• It works for both mobile and web and adjusts its UI accordingly
Walk With Me
FEATURES
• It can send SOS messages if there is any emergency, and all those who are nearby get notified right away.
• It has event creation and tracking so that users feel safe.
• It's integrated with local security groups that get notified in case of an emergency.
Remote Solar Monitoring System
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
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.
Nordic App for Prehistoric Site
• Ability to view maps offline using MapBox so that users could navigate even in remotest areas without internet
• View Artifacts/Site info by tapping over Map using Mapbox API to navigate the user to that place.
