Virtual Technical Assistant (Wix, Sqaurespace , Shopify Expert)

Type: Part-Time / Ongoing Freelance Location: Remote (Global – open to any location) Language Requirement: Native or professional-level fluent English Are you a platform wizard who loves the technical puzzle of building and integrating websites, but would happily never choose a color palette again? If so, let’s talk. I am a freelancer looking for a reliable, tech-savvy Virtual Technical Assistant to take the heavy lifting out of backend development, platform setups, and app integrations. No Design/UI Work: You will not be responsible for layouts, aesthetics, or branding. I will provide the designs, assets, and wireframes. Your job is to make them work. Key Responsibilities: Platform Setup & Customization: Build and configure websites from scratch or templates using Wix, Squarespace, and Shopify based on provided mockups. Coding & Development: Implement custom tweaks, fix bugs, and inject custom code (HTML, CSS, JavaScript/Liquid/Velo) when native platform features fall short. App & API Integration: Connect third-party apps, plugins, payment gateways, and tools (e.g., Zapier, CRM integrations, marketing automation). Technical Troubleshooting: Diagnose and fix broken links, responsive layout issues, or integration errors. Candidate Requirements: Platform Expertise: Proven experience under the hood of Shopify, Wix, and Squarespace. You know their limitations and how to work around them. Coding Skills: Strong foundational knowledge of HTML, CSS, and JavaScript. Experience with Shopify’s Liquid or Wix’s Velo is a massive plus. Problem Solver: A "get-it-done" attitude. If an integration is tricky, you enjoy troubleshooting until it works seamlessly. Reliable & Organised: Ability to manage your own hours, hit deadlines, and provide clear updates on tasks. I have three projects I currently need assistance with, but if we work well together I would be looking to continue on an ongoing basis as and when the projects come in. How to Apply: Please send over a brief introduction, your current hourly rate, and 2–3 examples of websites you’ve worked on (specifically highlighting any custom coding or complex integrations you handled). Please do not contact me via my website or LinkedIn PPH only. STRICTLY NO AI

Build a Secure Live AI Research Data Processing Prototype

Rapid Low-Code AI Document-Parsing Web Prototype (Secure Cloud Tenant) in Microsoft Copilot Studio / Azure OpenAI Project Overview: I need a highly concise, working prototype of a secure web application interface. The sole purpose of this app is to demonstrate a secure, live text-processing pipeline during a brief stakeholder review. It must ingest a raw text document/dataset, simulate a structured evaluation process against a pre-set compliance rubric, and dynamically display an optimization analytics page. Key Requirements to Implement: 1. Secure File Upload Interface A minimal, clean user interface with a file drop zone labeled: "Secure Sandbox: Upload Manuscript / Dataset Draft (PDF, DOCX, or CSV)". A secondary text field labeled: "Alternative Manual Input: Paste Methodology / Text Details". A dropdown parameter selector: [Parameter Group A / Baseline Metrics Checklist]. 2. Localized Governance Engine Setup Connect this frontend interface securely to an LLM endpoint (via Microsoft Copilot Studio, Azure OpenAI Studio template, or a standard private API pipeline). Define system prompts to parse the document's sections (checking for structural clarity, data mapping consistency, and alignment with baseline formatting rules). 3. Dynamic Output & Accountability Dashboard Upon document submission, the UI must refresh dynamically to show: Maturity / Verification Score: A clean progress gauge (e.g., Ecosystem Readiness Level: 84%). Compliance Rules Checklist: Visual indicators displaying: [Passed] Citation & Data Anonymization Check [Passed] Methodological Parameter Scope [Warning] Formatting Ambiguity Detected in Section 3 Actionable Next Steps: A generated text box detailing exactly what parameters need optimization. Technical Constraints: Must be deployed on a functional, live preview web URL so I can interact with it live during the meeting. Data privacy configuration must be explicitly set to ensure no data processed is utilized for public model training datasets. Important Fail-Safe: Hardcode a single specific fallback template path into the interface so that if the live internet connection fluctuates during the review, the target upload file will immediately trigger the exact correct completed dashboard layout cleanly.

Admin / content control: We need a basic content/admin layer to manage: - daily quotes - task templates / categories - basic recommendation content - AI prompt / config text - basic user / subscription visibility if possible This does not need to be a large enterprise admin panel, but important content should not be hardcoded only.

What tech stack would you use and why? 2. How would you handle AI memory / user context? 3. Have you built AI chat or AI assistant apps before? 4. Have you implemented Apple IAP and Google Play Billing before? 5. Would you use RevenueCat or direct Apple/Google billing, and why? 6. How would you structure the backend? 7.

Milestone breakdown with payment per milestone? 11. 2–3 real mobile apps you personally built? 12. Confirm source code and handover documentation are included. 13. Confirm payment is released only after each working milestone is approved. Please do not send a generic proposal. We are comparing multiple developers and will shortlist based on relevant AI app experience, subscription experience, strong architecture, fair pricing, clear milestones, and ability to understand product logic. Thanks.
