UI/UX & React Native Developer for "Sequence Harmonizer" Module

Project Overview:We are seeking an intermediate to expert-level cross-platform mobile developer (React Native or Flutter preferred) to build a standalone, minimalist custom module called the "Sequence Harmonizer." This tool allows users to view and interact with specific repeating numerical sequences. The design must be completely clean, premium, and entirely free of ads or external data-tracking scripts.Core Deliverables & Layout Flow:Four-Screen UI Flow: Construct a simple navigation path starting from a minimalist dashboard floating action button, through a first-time-only faded text intro block ("Sanctuary Onboarding"), and opening into the primary interactive matrix workspace.Interactive Matrix with 3D Flip Transitions: Implement a clean global toggle switch labeled "[ ✨ Spiritual │ 📜 Biblical ]". Activating this switch must trigger a smooth horizontal 3D card-flip animation across the underlying column layout to instantly swap themes:Spiritual Theme: Built with a Deep Space Charcoal background, Grounded Slate card borders, Glowing Violet headers, and Nebula Teal accents.Biblical Theme: Transits seamlessly to an Aged Parchment background style with clean Charcoal body copy and gold iconography.Data Sets & Dynamic Overlays: Build four interactive vertical column items mapped to our target numerical sets (17-68, 11:11, 333, 777, and 999). Tapping any column expands a beautifully typeset modal display showing its respective parable text, mathematical geometric reductions, or native Scripture reference hyperlinks.Visual Breath Pacers: Program native, silent visual canvas timing rings that support an automated 4-second box-breathing animation loop and a 9-second sensory grounding countdown.Strict Local State Wiper: For ultimate user data boundary protection, the module must utilize hardware lifecycle listeners. The absolute second the application enters a background state, or the device screen locks, the app must execute an immediate cache purge—wiping out all current calculation variables so it resets completely fresh upon reopening. Project Type & Workspace Terms:This is a highly structured, well-defined single module project. We prefer an individual freelancer over a large agency. We will structure the contract with fixed-price milestones tied directly to code delivery and visual interaction sign-offs over a 1 to 3-month window. Full documentation and color codes will be provided upon hire.
