Krostio
A full-stack income-verification product concept for gig workers and freelancers. The product organizes platform earnings into lender-ready income histories, consistency patterns, annualized projections and a shareable income passport.
Approach
Turn earnings data into a useful report
The product workflow connects gig-platform data through Plaid, then presents income history and consistency information in a report that workers can share with a lender. The Plaid integration is configured for sandbox data, not live financial connections.
Build a complete product surface
The repository combines a Next.js and TypeScript application with Supabase, authentication, worker dashboards and PDF report generation. That connects account access and data review to an output a user can take outside the app.
Keep platform integrations explicit
The codebase includes Paddle billing and a Solidity income-attestation contract targeting Base. The project documentation describes the Base deployments and Plaid sandbox; this portfolio does not present them as production financial services.
Outcome
A full-stack fintech product concept connecting gig-worker earnings, income summaries and shareable reports. Public documentation marks financial-platform data as sandbox and describes the product as a prototype.
