The Engineering Behind the Education

At rhidayat.work, we believe that a learning platform for developers should be as well-engineered as the systems it teaches. We didn’t want to build just another WordPress site or a generic LMS. We wanted a “Golden Stack” that reflects the cutting edge of modern web development.

🚀 Astro & Cloudflare: Speed at the Edge

By using Astro, we ensure that 90% of our pages are delivered as pure, lightning-fast HTML. Combined with Cloudflare Pages, we serve our content directly from the network’s edge, meaning a developer in Jakarta gets the same sub-second response time as someone in San Francisco.

⚡ Svelte 5: The Interactive Pulse

For our interactive “Editor Islands” and code sandboxes, we chose Svelte 5. Its new Runes system allows us to manage complex state (like real-time test execution) with minimal overhead, keeping our client-side bundle incredibly small and efficient.

🛡️ Effect TS: Functional Robustness

The “secret sauce” of our ingestion pipeline is Effect TS. When we pull 130+ challenges from external sources, we need to ensure that every single piece of data is type-safe and validated. Effect allows us to handle complex failures, translations, and file system operations with functional purity and extreme resilience.

Why it Matters for You

When you use rhidayat.work, you are interacting with a system built on the very principles we teach: performance, type-safety, and elegant architecture.

We aren’t just teaching you how to code; we are showing you what Engineering Excellence looks like in production.
