ML Coding Practice Platform

An interactive browser-based platform where developers solve real ML problems (attention mechanisms, diffusion models, RLHF) with instant feedback. Like LeetCode but for machine learning fundamentals.

Demand for applied ML skills has spiked since 2023 as companies hiring for LLM and diffusion-model work can't find engineers who actually understand the internals, not just API wrappers — that gap is real and growing. LeetCode and Kaggle are the obvious substitutes, but LeetCode stops at algorithms and Kaggle rewards outcomes over understanding mechanisms, leaving a genuine hole for something that drills attention math or RLHF reward modeling with tight feedback loops. A subscription model in the $15–30/month range is plausible given what engineers pay for interview prep, but the ceiling is low unless enterprise team licenses get traction, since the addressable audience of developers who want to go *this* deep is narrower than it looks. The most likely failure mode is content velocity: building and validating even a handful of high-quality interactive ML exercises is extremely slow, and if the problem set stagnates, retention collapses fast.
