UI/UX Designer Needed for Health & Finance Dashboard

Looking for an experienced UI/UX designer to overhaul a custom, locally hosted dashboard application. The app is a centralized hub used to track and visualize personal fitness metrics, health data, and financial cash flows in one place. A fully functional working version of the application already exists. The underlying architecture, data pipelines, and logic are established. I need a designer to take this existing user interface, conduct a UX audit, and design a significantly improved, polished interface. I have attached several screenshots of the current build so you can understand the exact density and complexity of the information architecture. Finance Modules (Money_Today, Money_Review, etc.): Dense data tables, marked-to-market drawdowns, cash flow visualizations, and tax posture tracking. Health Modules (Health_Today, Health_Review): Visualization of daily calorie deficits, macro tracking, body composition trends, sleep efficiency, and detailed daily protocol logs. Ops & Chat (Tools_Ops, Chat): A data pipeline monitoring screen and a built-in LLM chat interface. While the current build defaults to a dark mode / terminal inspired look, I am not married to this aesthetic. I want you to have complete creative control to determine the best visual direction for the platform. Whether you choose to evolve the current vibe or introduce a completely new design language, you will be entirely responsible for defining the typography, color palette, spacing, and overall aesthetic to maximize clarity and usability. Scope of Work: UX Audit & Refinement: Review the current functional screens and identify areas to improve user flow, information architecture, and layout efficiency. Complex Data Visualization: Design clean, intuitive charts, graphs, and data tables that combine dense health and financial data without making the interface feel cluttered. UI Overhaul: Establish a modern, cohesive visual identity (typography, color palette, component styling) for the dashboard. Responsive Layouts: Ensure the design translates well across desktop monitors for deep-dive financial reviews, and mobile screens for quick fitness logging. Ideal Candidate Profile: Proven experience designing complex web applications, fintech dashboards, or health/fitness tracking platforms. Expert-level Figma skills with a strong understanding of developer handoff. Comfortable working within the constraints of an existing functional app rather than starting completely from scratch. How to Apply: Please begin your proposal with a brief explanation of how you approach redesigning an existing application. Include links to 2-3 specific portfolio pieces that demonstrate your ability to design dashboards, data visualizations, or complex web apps.
