About

I am an Information Systems student based in Surabaya, Indonesia, working across systems tooling and native web interfaces. I build web applications with zero-framework Vanilla JavaScript, HTML, and CSS, and write system-level automation for Linux and Android environments.

On the systems side, I maintain root-level tooling like SkiaVK (Vulkan HWUI pipeline redirection) and DexForge (automated Dalvik/ART compilation daemon). On the web side, I build fast, accessible applications with clean semantic markup and zero runtime bundle overhead.

I avoid heavy frameworks when native browser APIs solve the problem with zero dependencies, lower memory footprints, and faster load times.

Capabilities

Systems & Runtime

  • Dalvik / ART Compilation Daemon Automated profile-guided AOT compilation driven by hardware specs and battery state.
  • Vulkan HWUI Rendering Pipeline configuration redirecting Android system graphics rendering from OpenGL to Vulkan.
  • 3-Strike Bootloop Fallback Fail-safe boot tracking mechanism that disables modules upon consecutive boot failures.

Web Systems & Architecture

  • Zero-Framework Web Applications Native DOM, modern CSS, and typed TypeScript with zero client-side framework runtime overhead.
  • Build-Time Static Pre-rendering Build-time HTML injection via Vite hooks for instant FCP, full SEO crawlability, and zero hydration lag.
  • WCAG 2.2 AA Accessibility Accessible semantic landmarks, keyboard navigation patterns, focus states, and high color contrast.

Projects

Bayu Bagus Bakery Web App (opens in a new tab)

B2B ordering portal built to digitize daily wholesale operations for a regional bakery in Nganjuk, East Java. Includes automated order calculation and Google Maps local indexing.

  • Interactive supply order calculator and native modal dialogs for a 14-item wholesale catalog.
  • Optimized with JSON-LD schema markup and WebP assets for local search indexing.

SkiaVK (opens in a new tab)

Star 22

Android root module configuring system UI hardware rendering from OpenGL to the Vulkan pipeline.

  • Configured Vulkan HWUI rendering to improve frame pacing and render latency.
  • Implemented a 3-strike bootloop fallback that automatically disables the module upon boot failure.
POSIX Bash Vulkan HWUI Android Root

DexForge (opens in a new tab)

Star 11

Android compilation optimizer daemon automating Dalvik/ART ahead-of-time compilation profiles based on hardware specs, thermal thresholds, and battery state.

  • Profile-guided compilation heuristics adapted to device RAM and processor specs.
  • Safety guards pausing background optimization when storage drops below 512MB or battery falls below 15%.
  • Hardware volume-key recovery boot menu to clear dexopt caches and restore defaults.
POSIX Bash Android ART Android Root
