"Recovering a career-quiz product from its original GitHub source, then expanding it into a two-axis scoring engine covering 26 tech roles — what stayed, what changed, and why."

1. Product Recovery and Modular Re-architecture

We took legacy single-file quiz code and converted it into a typed assessment engine supporting multi-trait vectors (Analytical, Creative, Operational, Algorithmic).

2. Zero-Sign Up Friction Loop

To maximize completion rates, the assessment runs entirely in client-side memory using state reducers, displaying interactive radar charts instantly without forcing account creation.

Architectural Takeaways

Immediate value delivery beats gated sign-up walls for consumer interactive tools.
Weighted vector math provides far higher user match accuracy than simple tally counting.
