I built a text-based business simulator to replace video courses
I am a solo developer, and I built Core MBA because I was frustrated with the "video course" default in business education. I wanted to build a "compiler for business logic"—a tool where I could read a concept in 5 minutes and immediately test it in a hostile environment to see if my strategy actually compiles or throws a runtime error. The project is a business simulator built on React 19 and TypeScript. The core technical innovation isn't just using AI; it's the architecture of a closed loop between a deterministic economic engine and a generative AI validation layer. The biggest technical…

In plain words
Core MBA is a text-based business simulator that lets users test business strategies in a simulated market environment. Built with React 19 and TypeScript, it combines a deterministic economic engine with AI validation to provide immediate feedback on whether strategies work. Designed for learners frustrated with traditional video courses, it lets users grasp a business concept and immediately run it through a hostile market scenario to see if their logic actually functions or fails. The simulator uses a custom discrete-event engine with mathematical rigor rather than AI hallucination.

I’ve noticed many engineers struggle with the "politics" side of things when they become Leads. To help with this, I’m building a text-based simulator. It is NOT an AI chatbot. It is a hand-crafted, branching narrative (logic tree) based on real experiences. I just launched the first scenario: "The Backchannel VP." The Setup: Your VP Engineering is bypassing you and giving tasks directly to your juniors, causing chaos. Your Goal: Stop the backchanneling without getting fired. It’s a short, specific puzzle. I’d love to know if you think the…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
