Finance Scenario Tool UI/UX

GreenLedger Markets is leaving spreadsheets behind and I need a UI/UX specialist to translate our early-stage wireframes into a polished, developer-ready experience. Your first task is the flow for creating and editing investment scenarios. Analysts will enter and revise assumptions, risks, and market conditions constantly, so the interface must make those updates effortless. I want interactive sliders and other quick-adjust controls that let users see the impact of a change in real time without wading through grids of numbers. What I already have • Core workflows mapped in rough sketches • A component inventory from our brand team • Sample data sets for testing interactions What I need from you 1. User flows and high-fidelity screens (desktop-first, responsive in mind) that walk a user from “New Scenario” through save, duplicate, and version history. 2. An interactive prototype in Figma (or Sketch + InVision if you prefer) showing the dynamic slider behaviour for key fields. 3. A lightweight design system: colour, type, spacing, and a reusable component library so developers can drop assets straight into code. 4. Clear specs and redlines for handoff, including states, error messaging, and accessibility notes. Acceptance criteria • A senior analyst can build a scenario, tweak three different assumptions with sliders, and immediately view recalculated outputs in under two minutes. • All components conform to WCAG AA colour-contrast and keyboard-navigation standards. • Deliverables are packaged in a single shared Figma file with pages for Flows, Components, and Prototype, plus a PDF summary deck. If this sounds like your kind of challenge, let’s talk timelines and milestones.
