- pending
- Needs two observations at least 14 days apart. Our next read of this page turns this on. Nothing is extrapolated from a single contract.
- Lifetime pace
- $29.4K/yr estimate
- Lifetime earnings divided by years on Upwork. A floor on historical pace, not a forecast.
- Earnings per job
- $1.3K
- Average contract value to date.
- Recent earnings, per Upwork
- $11.1K
- The "recent" figure Upwork attaches to the directory card, with 125 recent hours. Upwork does not publish the window, so it is shown as its number, not ours.
- Realised hourly
- $107/hr
- Total earned over billed hours. Fixed-price work inflates it; compare with the rate card.

About
UX/UI Design & Development Agency | Marketplace, SaaS & Fintech Platform Specialists At U1CORE, we design and build two-sided and multi-sided platforms — systems architected around real buyer-seller, client-provider, and vendor-admin behavior. We turn complex multi-sided logic into experiences people actually understand and trust. WHAT WE DO 🔹 B2B Marketplace Design & Development Account-based pricing, approval workflows, multi-tier buyer hierarchies, RFQ and quote-to-order flows, ERP integrations. Built for procurement reality, not retail logic. 🔹 Service & Gig Marketplace Design Two-sided platforms connecting providers and clients — booking flows, trust signals, dispute resolution, review systems, commission structures, Stripe Connect payouts. 🔹 Vendor Onboarding & Seller Activation Progressive flows that move vendors from sign-up to first transaction — the metric that decides whether your marketplace lives or dies. 🔹 Two-Audience Landing Pages Pages built to grow supply and demand at once, with separate value propositions and conversion paths for each side. 🔹 Wireframing, Prototyping & Marketplace Architecture Full vendor, buyer, and admin flow prototypes — so marketplace logic and role-based permissions get validated before a single line of code is written.
