My personal branding website's design was inspired by Medium and I received design advice from Didan Putra, Anyoy, Yesyes, and LeonVolcove.

• Creating a personal branding website using React, Next Express, MongoDB, and Node (MERN Stack).
Frontend :
• Developed using Next.js hosted on a personal VPS at https://z3rsa.com.
• Ensured responsive design for optimal viewing on mobile, tabs, laptops, and PCs
Admin Panel (Custom CMS) :
• Built with React hosted on a personal VPS at https://admin.z3rsa.com.
• Implemented authentication using Redux and integrated RTK Query.
Backend :
• Utilized Express.js and Node.js. Hosted on a personal VPS at https://api.z3rsa.com.
• Implemented rate limiting to prevent server overload.
Cloud Database :
• Leveraged MongoDB Atlas as the cloud database solution.
Enhanced website security and performance :
• Utilized Cloudflare for protection against cyber attacks and to address caching issues.
Monitoring :
• Utilized Uptime Kuma, hosted on a self-hosted Docker environment, to monitor both the frontend and backend at https://status.z3rsa.com.
Performance Improvement :
• Utilized Partytown for the purpose of lazy-loading libraries, I effectively relocated resource-intensive scripts into a web worker, consequently reducing the workload on the main thread.
Statistics & SEO :
• Leveraged Google Analytics 4 to obtain valuable insights and statistics.
• Made efficient use of Google Search Console and its reports to measure site Search traffic and performance, resolve issues, and enhance the visibility of the website in Google Search results.
