Hi,
I'm Khomsun
A qualified software developer with 15 years of experience with excellent skills in analyzing and modifying existing software, as well as developing, designing, and testing end-user applications that match user needs (Desktop, Web, Mobile, and Services) with technical skills in Java, PHP, HTML, JQuery, Javascript, JS Node, Android Studio, React Native, MySql, Oracle, and PostgreSQL.
I have developed software while working and has been implemented in several companies such as Automatic Meter Reading, AiSystems Gateway, Virtual Com, Inventory Application, SMS Gateway, Fuel Monitoring, and Kataba Education Platform.
In addition, I also handle personal projects, and create applications according to customer needs such as Travel ticketing management, Cable TV Billing Systems, Point of sales Applications, School Applications, and Financial Applications.
I like analysis, system design, experimentation, strategy, and problem-solving, and like to learn new things. Interested in digital marketing because in the long term I want to create a system that can be marketed digitally. To achieve that goal, I joined the Full Stack Digital Marketing (FSDM) program from Revou to increase my skills and then began to hone my thinking skills and marketing strategies which will certainly be useful for me in the future.
If your company needs a software developer or digital marketer, I am ready to help increase the company's growth with the skills I have.
