Hi there! Get in touch if you need an easy to work with and versatile lead/senior iOS developer for your app or platform that needs good performance, appealing user experience, and AI integration. I'm a developer and cofounder (indie game) specializing in graphics optimization (Metal/OpenGL), real-time visualizations, and embedding ML models for on-device inference. Experience with LLM fine-tuning, vector search, computer vision, and converting large models to compact on-device implementations. Led development of an App Store-featured app WikiNodes, and games with multiple awards. Recently built a word game system navigating 1.5M+ words with 110M+ relationships using Metal shaders at 60fps, plus shipped computer vision features and cloud-based agent architectures.

I’m working on In Other Words, a daily word puzzle where players connect seemingly unrelated words through conceptual stepping stones. The game showcases how any two words can be connected through surprisingly few steps — we’ve crafted each puzzle to need at least 3 hops, with around 50 elegant 3-hop solutions hidden among thousands of possibilities. When players explore longer paths (up to 9 hops), they can discover millions of valid solutions among billions of potential routes. It’s fascinating to see how words like “ground” can bridge entirely different concepts, or how homographs create unexpected connections between semantic domains. The game advances the “idea-linking” category of word puzzles — focusing on meaning rather than spelling or anagrams — and turns our linguistic network into a daily brain teaser where finding your own creative path is as rewarding as discovering the most elegant solution.
It’s for iPhone only (yes, sorry!), and you can play for free once. Apologies in advance for the large download. Get it from here: https://www.inotherwords.app/
