About Jiahan

Full Stack Developer with over 10 projects delivered between independent websites and mobile applications. I specialize in WordPress, custom web development, and comprehensive project management — from initial idea to final delivery.

What I do:
• Develop custom WordPress sites with careful design and attention to visual detail
• Complete web and mobile applications (frontend + backend)
• Integrations with REST API, MySQL databases, and other backend technologies
• Autonomous project management from start to finish

What sets me apart:
I don't just code — I design with purpose. I combine solid technical skills with a strong aesthetic sense to create digital products that perform well and look even better. Every project I deliver is designed to generate real results for your business.

If you're looking for a professional who can handle your entire project without compromising quality or vision, let's talk.
