About this Service
The handoff is where most products quietly become a different product.
Design finishes, files go over the wall, and three weeks later the build has an extra confirmation step nobody approved, a fee shown after the amount instead of before it, and an offline state that just spins. Nobody lied. A developer hit a case the design didn't cover, made a reasonable call under deadline, and moved on. Multiply that by two hundred decisions and you have software that works and doesn't feel like what you signed off.
In operations and finance products that gap costs more than elsewhere, because most of the product is edge cases — the lost signal, the declined payment, the expired document, the route that changes mid-shift. Those are the screens a handoff never specifies and a deadline always rushes.
Running two vendors makes it worse: now there's a seam, and each side can point at the other.
We don't hand off. Design and engineering sit in the same team and the same weekly cycle, so edge cases get resolved once, by two people who both own the outcome.
In two months you get a working product — designed, built, integrated, tested and deployed. Code and design files are yours.
How it runs:
— Week 1–2: discovery, core flows, and the constraint map — integrations, providers, regulatory or operational limits — locked by design and engineering together, so nothing gets specified that can't ship
— Week 3–5: design and build in parallel, with weekly working builds you can actually use, not screenshots
— Week 6–8: edge states, QA, performance, security, deployment and handover
What you get:
— Full UX and UI in Figma, with a component library
— Production frontend built against that library
— Backend and API work, or integration with your existing stack
— Integrations: telematics and ELD providers, payment rails, KYC and verification services, ERP and third-party APIs
— Admin, dispatch and support tooling
— Responsive web, plus native mobile where the product needs it
— Testing, deployment, documentation and handover
— Your code, your repos, your design files
Typical engagements: MVP design and development, fleet management and logistics platform build, driver and field app development, telematics product build, fintech and payments product development, neobank and digital banking apps, B2B SaaS platform launch, internal tools and admin systems, product rebuild and re-platforming, design-to-code delivery.
We work as one team at U1CORE — design and engineering together, so what gets approved is what gets shipped. Platforms in this portfolio have processed $720M+ in production payments.
