Austin Ha

About

Senior engineer (8 years) with experience at Facebook/Meta and Apple, spanning design tooling and XR/enterprise device experiences. Built the Origami component marketplace end-to-end (packaging node logic + metadata, SQL/JSON storage, filtering/search, local caching) with versioning and forward-compatibility decisions, and has a strong track record of UX-focused robustness improvements and safe rollouts via feature flags and telemetry.

Key Strengths

• Designed and shipped a component marketplace with metadata, versioning, and discoverability
• Performance optimization via local caching to reduce perceived latency
• Thoughtful compatibility tradeoffs (forward-only compatibility across app versions)
• Risk-managed rollout using feature flags and telemetry before full release
• Strong error-handling mindset for API design (clear no-op/error signaling, sanitization)
• Cross-functional collaboration with designers to spec polished UI flows
• Detail-oriented UX robustness improvements (consistent zoom behavior, cursor-relative zoom)
• Improved user experience during input limitations via no-op feedback animations
• Mixed reality multiplayer feature implementation (shared coordinate systems via Azure Spatial Anchors)
• Strong 3D math/coordinate system precision for spatial alignment
• Networking experience in AR/VR (Photon replication + voice)
• Builds reusable prefabs enabling rapid designer-led prototyping without code
• Architects and implements core logic with deep codebase understanding for debugging/maintainability
• Tech lead experience building Unity prototyping infrastructure and workflows
• Multi-platform build automation including Quest as a target
• Built HoloLens 2 onboarding and gesture tutorial experiences in Unity using additive scene loading
• Strong cross-functional collaboration with designers, artists, audio, and shader contributors
• Creates tools that enable non-engineers to prototype in Unity via prefabs
