A gig platform lives or dies on its data model: how profiles store skills and experience, how job posts map to searchable categories, how bids or proposals flow from contractor to client, and how each transaction state tracks through the system. We design the relational schema and API surface before a line of product code runs, because retrofitting a marketplace's core data model after launch is the most expensive fix there is.
Client-side flows cover job posting, brief templates, contractor discovery and shortlisting, proposal review, and project management dashboards. Contractor-side flows cover profile creation, portfolio upload, skills assessment, bid submission, and earnings tracking. Both sides are built for web and mobile, with a platform admin console covering dispute management, fraud flags, and payout approvals.
The architecture is built to support open marketplace models, curated network models, and hybrid approaches where some talent categories are open and others are invite-only or pre-vetted.
