Problem

As Rust demand surges, more candidates claim 'Rust experience' in the job market, but hiring managers — especially at Korean SMEs in IT — lack coding test problems and grading rubrics that properly assess Rust skills. Existing coding test platforms (Programmers, HackerRank, etc.) offer mostly algorithm-focused Rust problems that fail to evaluate systems programming competencies like ownership, lifetimes, and unsafe usage.

Solution

(1) A bank of 100+ hands-on coding problems organized by Rust-specific concepts (ownership, lifetimes, concurrency, FFI), (2) automated grading (compilation, tests, clippy linting, unsafe usage auditing), (3) auto-generated assessment reports by seniority level (junior/mid/senior). Differentiator: Korean-language problems + result reports tailored to Korean company hiring processes.

Target: Hiring teams and HR managers/CTOs at IT companies with 10–100 developers
Revenue Model: Per Transaction billing — $11 per test session (1 candidate), monthly package at $90/month (15 sessions included)
Ecosystem Role: Education
MVP Estimate: 2_weeks
