About

I’m a developer who likes figuring things out by building them. I started with web development, building interfaces and backend systems for products with real workflows rather than isolated demos, and over time I became more interested in the decisions underneath the interface: how data moves, how state stays consistent, and how different parts of a system affect each other.

More recently, I’ve been learning native development at Apple Developer Academy. Projects like Astrocat pushed me into game physics, real-time multiplayer, and architecture patterns that were unfamiliar to me, while UpDish gave me a chance to work with model-powered features inside a native iOS product.

I’ve also experimented with machine learning and deep learning, and have integrated AI models into applications. Lately, I’ve become curious about LLMs, retrieval, RAG, and agentic systems. I’m still exploring that space; I’m more interested in understanding what these systems are actually good for than adding AI to a product for its own sake.
