Experience

Just Dabao

http://justdabao.com/

A Flutter-based app that allows users to order food at discounted rates from restaurants. 它还使商家能够通过减少食物浪费来节省资金. The app uses location-based filtering to track orders and give users the best option available.

这款应用就像是美容造型师的优步, an on-demand app where users can book stylists and also it provides real-time tracking and online payment systems, allowing the entire process to take place within seconds and giving customers the flexibility to book a stylist from the comfort of their homes.

Social App for Travellers

A React/Flutter-based app for social networking between users to communicate and share details about their travel stories, and it had a map-based interactive messaging system for the users to communicate with each other and view their travel stories over a globe-based interface using MapBox, as well as it allowed users to check all the available stories for a particular area on the MapBox Globe using heatmaps.

Orijin Plus

http://www.orijin.plus/

The app is an eCommerce for wholesalers with a system that involves the usage of Mapbox and that enables users to track and verify the authenticity of their products and the users can also see the whole journey of the product saved on the blockchain, 了解他们的食品来自哪里, how they are made, 以及推动公司发展的原则.

Geolocation-based广告/提供

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.

这有助于客户向用户发送有针对性的广告/优惠，并带来更好的结果.

如果你在一家与客户有合作关系的咖啡店附近, 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. 即使没有网络或手机关机，它也会毫无问题地恢复.

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

http://apps.apple.com/sg/app/carte-bonjour/id742161961

这是一款基于flutter的应用程序，可以用作移动钱包，用于支付停车费.

太阳远程监测系统

该系统是启用30年的太阳能逆变器, 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, 使用rs42到Modbus连接器连接到这些设备, and then I tracked the incoming packets using Wireshark and then decoded what was sent to the old computer.

Using Node.. js和Python代码, 我可以和那个装置交流, 我使用MQTT和Restful api将数据发送到服务器.

Grafana was used to convert the real-time data into dashboards and allowed a visual representation of the data. Telegraf还用于将原始数据转换为所需的格式.

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. 然后，使用这个值，我将这些信号连接到树莓派. 然后，信号将使用使用Wifi加密狗的MQTT向服务器发送数据. 这使得客户可以随时检测加热器是否有任何异常.

北欧应用程序史前遗址

A Flutter-based app that displays all the artifacts found on a prehistoric site from the Nordic region, and the app uses Offline Maps using Mapbox along with panoramic views to show 3D Images using Google panoramic API to give an immersive experience to the users.

• 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.
