Syntax Code Lab icon

Syntax Code Lab

A dynamic developer and business portfolio site to list the owner's featured projects, blog articles, profile, skills, experience, access-controlled resume, and a contact form to communicate with visitors. The highlight of the site is the full-function content management system (CMS) in the backend with secure Google and GitHub OAuth authentication and authorization. Every piece of content, from profile tagline, experience, to the site's legal documents, such as privacy policy, can be updated through the CMS without having to redeploy the site. It also comes with a resume-building system that automatically generates a professional-style resume PDF file for the owner and hiring parties. The CMS is also equipped with a powerful blog publishing system to write, format, publish, and unpublish blog articles.

Welcome to Syntax Code Lab

Happy to introduce my developer portfolio site today. It's been a dream to have a site of my own where I can consolidate the work I've done in recent years since I decided to switch career path.
