Freelance Marketplace
A two-sided freelance marketplace — job listings with search/filtering, proposals, accept/reject, and per-listing messaging scoped to the client and accepted freelancer — built entirely on our own custom BaaS platform, with zero hand-rolled backend. Shipped as a reference implementation across 9 languages (TypeScript, Python, Go, Ruby, Java, C#, PHP, Swift, Dart) plus native iOS and Android, with strict server-side ownership checks (IDOR-hardened) verified in every port.
