Welcome to my personal website!

This is my first side project since I started my professional career on September 2021 (as a full-time Frontend Software Engineer)

Live at https://nguyenfromvn.github.io/

Highlights:

• A music radio that can play music uninterruptedly, even when the network is slow or losing connection, or even if the screen is off or the device is locked (Android devices)
• Well performance optimizations including dynamic fps limit, using custom code instead of JavaScript builtin functions, precise timing for heavy tasks, using the Performance tab of Dev tools, etc. resulting in a very smooth experience with high framerate, even on mobile devices
• Fault tolerance crypto price tracking widget that can recover to work properly after an interruption event (caused by networking issues, etc.)
• Precise time info from the clock widget, it matches the system's time in seconds
• No framework or library involved, everything is written from scratch

Features:

• A music radio with a long list of good songs
• Music visualization, emphasizing bass and treble
• Creative and beautiful-looking design
• Good optimizations to deliver high framerate
• Crypto price tracking in real-time using Binance WebSocket
• Current weather info using OpenWeatherMap API
• A clock widget to show date and time
• A small game in the background where people can interact with the falling dots behind an invisible wall

Notes:

• Users should consider using Chrome browser (on PC and mobile devices) for the best experience as most of the logic is implemented based on the documentation of Chrome
• Currently, browsers on iOS do get some restrictions, especially on audio playback and background stuff. I spent more than a week just to make sure the audio was played correctly on iOS. Still, the audio will stop immediately after the screen turns off or the user switches to another application
• Another known issue on iOS is about opening a new tab, iOS tends to block "pop-ups" and thus, opening new tabs may get banned and only can be done if the user does allow that
• Because audio is playing via a browser, not directly when compared to a native app, and thus, sometimes, the audio playback can be throttled or the tab can be even reloaded due to memory need for other purposes
