I create practical programming tutorials focused on real-world development. Topics include iOS development, React / JavaScript, Python, APIs, tooling, and system automation - explained simply and clearly. I also build apps and tools, including a Stock Market Simulator (paper trading) app called “Stock Sim: Paper Trading” that helps people practice investing risk-free. Available on the App Store for download. New videos focus on building, learning, and shipping real software.
