Hacktoberfest Open-Source AI Challenge Week 2: Side Hustle Submission 💸

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 2: Side Hustle

A freelance web developer friend recently accepted a $600 fixed-price landing page gig on Upwork that promised "a few minor tweaks after launch."

By the time the client finished requesting five separate rounds of unbilled layout revisions, Net-30 payment delays, and Upwork deducted its 10% processing fee, their effective take-home pay collapsed below $11.40 an hour —well under minimum wage.

Existing SaaS pricing tools cost $25–$49/month and require uploading confidential client contracts and raw bank CSVs to third-party proprietary clouds. For a side hustle clearing $400 to $1,500 a month, paying a recurring subscription to hand over proprietary pricing data is a losing trade twice over.

MarginPulse AI is an open-weight autonomous CFO, calibrated quantile deal pricer, and scope-creep shield that turns any messy historical CSV ledger and an incoming client inquiry into three concrete outputs in under two seconds:
