👋 Hi! Im William

Developer trained through the Apple Developer Academy @ UC Indonesia, focused on building polished, production-ready apps with Swift & SwiftUI.

I shipped 5+ apps across iOS, iPadOS, and macOS during the Academy, averaging a 4.8/5 pilot satisfaction score. My favorite build is Menata, which uses RoomPlan, Object Capture, and RealityKit to let interior designers scan and arrange rooms in 3D.

Beyond mobile, I bring full-stack range — AWS serverless architecture and time-series forecasting — so I can work closely with backend and data teams while owning the iOS experience end to end.

I'm also deliberately growing alongside AI tooling — using models like Claude, Gemini, and Copilot inside AI-native editors (Antigravity, Cursor) to move faster, and shipping to Vercel to close the loop from prototype to production.

📦 5+ shipped projects  ·  🛠️ 3 years building  ·  🎓 GPA 3.71 / 4.0

🤖 Building & Growing with AI

I treat AI tools as a skill to develop deliberately, not just a shortcut — using them to work faster and to understand the systems well enough to build with them.


  • Workflow speed — pairing with Claude, Gemini, and Copilot inside Cursor and Antigravity to move from idea to working code faster
  • Building AI-native features — integrating AI directly into my own apps (not just using AI to write code, but shipping AI-powered functionality to users)
  • Systems literacy — going deep enough on how these tools work to talk about them from either the engineering or the product/BA side
