Flutter Package — Image Reshttps://pub.dev/packages/image_res
I created this tool because handling resolution-aware image assets can be laborious and time-consuming for developers working on their Flutter projects—they need to arrange the assets according to a particular directory structure; otherwise, Flutter cannot load resolution-appropriate images that fit the current device pixel ratio.
Image Res is now available through pub.dev, the official package repository for Dart and Flutter apps. Other developers can easily install and benefit from it.
ViaBus — Transit Tracking and Navigationhttps://www.viabus.co
Users can find transit stops and routes for over 20 cities in Thailand by using the ViaBus app. It also allows them to monitor real-time buses as they approach their stop and provides them with recommended routes from point A to B.
As part of my responsibilities, I collaborated closely with a designer to translate the idea and build a landing page for ViaBus using Angular.
Globish Dashboard — Online Class Booking Flowhttps://dribbble.com/shots/6366614-Globish-Dashboard-Online-Class-Booking-Flow

Working with a development team, I implemented the front-end web app using Vue.js and modernized the dashboard for mobile and desktop experiences.
Stamp — Membership and Loyalty Program on Your Mobile Phonehttps://dribbble.com/shots/8099079-Stamp-Membership-Loyalty-Program-on-Your-Mobile-Phone
