About

I specialize in high-performance iOS development, bridging technical innovation with intuitive user experiences. My work spans graphics programming, AI integration, and game development, with particular expertise in Metal shaders, force-directed layouts, and on-device machine learning.

As technical co-founder of In Other Words Studio, I recently launched a successful daily word puzzle that challenges players to navigate semantic relationships through an engaging visual interface. This experience exemplifies my approach to development: solving complex technical challenges while maintaining focus on user experience and performance.

With over a decade in iOS development, I've led multiple projects from concept to launch. I'm currently open to new opportunities where I can apply this expertise to ambitious technical challenges.

In Other Words Icon

In Other Words transforms a decade of research into semantic relationships into engaging daily puzzles. As technical co-founder, I engineered systems that bridge computational efficiency with human intuition, developing innovations across several domains.

  • Word Selection Engine: Developed a hybrid system combining traditional embedding vectors with weighted graph traversal to model nuanced word relationships
  • Adaptive Hint System: Engineered a ray-tracing inspired algorithm that efficiently samples solution paths through semantic space
  • Visual Interface: Built a high-performance iOS frontend using Metal and custom shaders, with force-directed layouts maintaining fluid 60fps interaction

The technical architecture balances computational constraints with cognitive patterns, letting players discover meaningful paths between concepts. Read more about the technical journey and design philosophy behind the project.


OtherWordly Icon

OtherWordly is a unique arcade-style game app that takes you on a galactic quest to connect related words. As the lead developer, I created the game's immersive word-matching mechanics, procedural obstacle generation, and AI-driven opponent behaviors using Swift, Metal, and advanced NLP techniques. The game has received critical acclaim.


I've led groundbreaking projects like SpicyNodes and App Store-featured applications such as WikiNodes.
