Used Combine to handle asynchronous data streams and bind API-driven updates to the UI. Implemented reusable and scalable content sections for sneaker discovery, integrated local persistence with Core Data, and connected external APIs to support updated product data and browsing flows. Identified and resolved issues across UI, navigation, data binding, API integration, and state management. Integrated AI-assisted workflows using OpenAI Codex CLI and ChatGPT for repository analysis, debugging, refactoring, implementatio
