Welcome to HackerNoon’s Projects of the Week, where we spotlight standout projects from the Proof of Usefulness Hackathon, HackerNoon’s competition designed to measure what actually matters: real utility over hype. n n Each week, we’ll highlight projects that demonstrate clear usefulness, technical execution, and real-world impact – backed by data, not buzzwords.
This week, we’re excited to share three projects that have proven their utility by solving concrete problems for real users: Black Market SSP, CutePetPal, and SudoDocs.

Meet the Projects of The Week
Meet Black Market SSP
https://hackernoon.com/black-market-ssp-earns-a-60-proof-of-usefulness-score-by-building-real-time-currency-tracking?embedable=true
BlackMarket SSP tracks black market and official currency exchange rates, plus daily petroleum production in South Sudan.
The project addresses a specific, high-utility problem in South Sudan regarding currency instability and petroleum tracking.
Black Market SSP exists because currency instability and the gap between official and parallel rates in South Sudan create an urgent need for transparent, real-time financial information for everyday citizens.

Meet SudoDocs
SudoDocs is a documentation-as-a-code tool that acts as a “unit test” for documentation by connecting to Git repositories and Jira to detect when code changes differ from existing docs.
It use Google Vertex AI (Gemini) to analyze semantic drift in code diffs and automatically drafts accurate updates, ensuring your documentation never lags behind production code.
SudoDocs serves product teams to quickly validate OpenAPI specifications and automatically correct the mistakes in it. This allows technical writers, product owners, and software developers leverage the best documentation for their product.
SudoDocs exists because rapid release cycles are outpacing manual documentation updates, creating a critical need for automated solutions that treat documentation as code.
