Hi, my name is

Exy Wartono

WordPress Developer

Experienced WordPress Developer with a focus on building engaging, flexible & easy-to-manage websites. Currently working at U Digital.

In my spare time, I share what I learn on my blog and offer some freelance services on Fiverr.

01. About Me

I am a WordPress Developer with over 4 years of experience in building, developing, and optimizing various types of websites for individuals, businesses, and organizations. My specialization includes custom theme development from scratch, custom feature development using PHP, JavaScript, and WordPress, as well as the implementation of Advanced Custom Fields (ACF) to create flexible and easy-to-manage websites.

In every project, I prioritize performance, security, and ease of use to ensure that websites not only look appealing but also function optimally. Additionally, I have experience integrating websites with various third-party services, performing data migrations, and providing regular maintenance services to ensure the stability and security of websites.

Here are a few technologies I’ve been working with recently:

  • WordPress

  • NextJs
