🤝 Hire me

This is my first project. The purpose when I did this project was to implement single sign-on (SSO) between 2 software, "vBulletin" (Community software was quite popular at that time) and "Ucenter Home" (Software to help build social networks). The project has achieved great success when receiving a lot of welcome from the community.

In June 2011, my close friend “DuyK” and I built a website called “daica.info”. We aim to create a meeting place for people who share the same interest in programming. It has helped me exchange and learn a lot of new knowledge about programming and technology. In this project, I act as the lead developer. After nearly two years of operation, we closed the website because we could no longer spend much time and money to develop it.

The tech stack that I used for this project includes:

• PHP is used to build the backend.
• The DBMS we use is MySQL.
• We use jQuery for the frontend.
• The web server we use is Nginx.

At the beginning of 2012, I built a community for hacking and security enthusiasts (anonvn.net). During that community development, I made 2 DDoS tools named Piglet (Written in Javascript) and XoneDos (Written in AutoIt). Creating these two tools gave me a deeper understanding of the denial of service attack method and how to fight it later.

In 2013, when websites about sharing links to watch football without copyright were a new trend in Vietnam, I researched to build such a site for myself.

The first time I had a lot of trouble was when I learned about SopCast, Ace stream, and video streaming technology. But in the end, I succeeded, my website got a lot of visitors. My site's peak had about 27K CCUs (Google Analytics).

This project has helped me gain a lot of valuable experience. I learned many things about video streaming, FFmpeg, CDN, optimizing websites to serve more users...

The tech stack that I used for this project includes:

• Laravel is used to build the backend.
• The DBMS I use is MySQL.
• I use Redis to cache data.

• I use jQuery for the frontend.
• The web server I use is Nginx.
• The server I use on AWS EC2 and CDN is Cloudflare.

This is my first outsourcing project. The client's request was to build a football news website. Doing this project, I have accumulated a lot of experience building news website systems, CMS, image optimization...

Hiweb is the most recent company I worked for and can be said to be the company I have been with the longest (I started working at Hiweb while working at iCheck).

Due to business and technology confidentiality reasons, I cannot publish the details of the projects and their tech stack here.

Most of the tech stack I've used at Hiweb is similar to what I did for iCheck, with improvements based on my experience working at iCheck.

This is the mobile app I created following the Pokémon GO trend at that time. It was immediately rejected by Google Play store for copyright infringement 🤣 unfortunately for my first time making mobile app. But I still feel like I've had some success learning more about React Native and mobile apps.

The Tech stack I used in these two projects includes Go, PHP, Nodejs, Nginx, Sass, Algolia, Stripe, Paypal. The cloud providers that I used are AWS, Google Cloud, and Cloudflare.

[x]Player (I can't think of a name for it yet) is an app that I created to watch videos on mobile phones. Currently, I only share it with my family. I will complete this application and publish it to the App store when I have more time.

I'm using Flutter to build this app.
