Hi, I am Leo.

I'm an information systems professional, designer, and entrepreneur.

I get inspired by technology so much that I tend to incorporate IT into my life and business. I've been working at multiple jobs for 8 years and doing business for 7 years. My philosophy in life is “Have passion, and succeed.”

Best Resume Maker

An online resume editor that helps you create your own professional profile based on years of real-world experience and practical techniques.

Awesome Vision

The web app that helped Pokemon GO players find Pokemon easily and fast.

Collected data from the game server and used geo technology to locate Pokemon and display them on a map. Support was discontinued, but a simulated proof of concept is here.


The crowd-sourcing Android app that helped Pokemon GO players record and view Pokestops and Gyms conveniently.

The app follows the user by recording the current location with GPS. Whenever there's a Pokestop or a Gym, the user can signify it and the place of interest would be recorded and shared to the community.

Tự Điển VN

A cloud English-Vietnamese dictionary that delivers result immediately as the user types, at lightning speed.

Utilizes high speed technology and adaptive memory to be as fast as possible.

Thanh Vắng

An immersive audio website that plays the sounds of nature. Suitable for personal productivity or relaxation.

The user can have the system mix automatically or customize sounds completely and freely.


A custom theme that is finely designed and carefully crafted to transform the vanilla Bootstrap look into the modern and far more aesthetically pleasing interface.

Auto Backup

A lightweight, one-file, direct-run, and PHP-based automatic backup solution that keeps a copy of your files and optionally database, then sends to a safe destination of your choice. Supported compression and FTP.

Easy, fast to configure. Let it run indefinitely with system call, direct web access, or cron.


A blazingly fast live-keystroke search tool to look up songs for the Arirang karaoke system.

Supports multiple search schemes, such as whole word search, partial text search, and the state-of-the-art first-letter search. Also sorts search results based on relevance.

Giúp Miền Trung

An online charity campaign that raised emergency funds for victims affected by severe storms and floods in Central Vietnam in October 2016. I created on a emergency-rush run within 3 days.

Collected $8,800 of direct online donations, creating credibility, prestige, and momentum leading to the success of subsequent offline events that eventually totalled over $50,000.

Next project, with me!
