JavaScript / Wix Velo Architect for Proprietary Clinical Algorithmic Web Application

Job Title: JavaScript / Wix Velo Architect for Proprietary Clinical Algorithmic Web Application Job Category: Web Development / Front-End Development / JavaScript Project Type: One-time project (Phase 1), with immediate potential for Phase 2 (API/OCR Integration) Project Overview: I am a Consultant Ophthalmic Surgeon seeking a web developer to translate a proprietary, complex medical algorithm into a secure, interactive web application. The mathematical framework, clinical logic trees, and UI grid architecture are already 100% completed and mapped out in a locked Excel spreadsheet. Your mandate is to take this strictly defined logic and build it into a highly polished, reactive web calculator deployed via the Wix Velo (JavaScript) environment. Technical Scope of Work: UI Implementation: Construct a clean, responsive medical user interface within Wix matching the provided structured layout. Algorithmic Translation: Convert complex, multi-tiered Excel logic (including nested IF statements, algorithmic baseline corrections, and adaptive clinical staging) into clean, performant, and well-commented JavaScript. Strict Data Validation: Implement rigid front-end input restrictions. You will lock numerical inputs within specific physiological limits (e.g., CCT constrained between 300–850 µm) and deploy error-handling states for out-of-bounds data entry. Dynamic DOM Manipulation: Code reactive DOM elements that alter text output and CSS styling (color states) in real-time based on calculated clinical risk thresholds (e.g., dynamic flagging of ISNT rule violations based on dimensional asymmetries). Strict Confidentiality & IP Requirements: Due to the proprietary nature of this clinical tool, the security of the intellectual property is paramount. Non-Disclosure Agreement (NDA): A legally binding NDA must be signed prior to the release of the architectural Excel file. Work for Hire: This contract will be executed strictly as a "Work for Hire." The client retains 100% exclusive ownership of all intellectual property, algorithms, logic matrices, and final source code. Data Destruction Clause: Upon final delivery and project sign-off, the developer is legally required to permanently delete all local copies, cached instances, and cloud backups of the proprietary algorithms and source code. Required Freelancer Qualifications: To be considered for this project, you must meet the following criteria: Earnings History: A proven track record of substantial earnings on Upwork, demonstrating a high level of professional integrity and business acumen. Technical Stack: Expert-level proficiency in vanilla JavaScript, HTML5, CSS3, and specifically the Wix Velo API. Prior Experience: Proven experience translating complex financial, engineering, or medical calculators from Excel into responsive web applications. Application Instructions: Agencies utilizing automated bidding bots will be immediately dismissed. Please begin your proposal with the exact phrase "Clinical Logic 2026" to confirm you have read this brief in its entirety. Include 1 to 2 specific portfolio links demonstrating logic-heavy web applications or custom calculators you have architected from scratch. Dr. Deepak Kumar Gupta Consultant Ophthalmic Surgeon
