I have a production-ready React/TypeScript health record web application built with Lovable (AI app builder) that needs to be migrated to professional infrastructure I own before public launch. I also need Claude Code (Anthropic's AI coding CLI) set up so I can continue building features independently after migration without relying on Lovable. This is a one-time migration project with a clear scope and a complete data export already prepared. I need someone experienced, detail-oriented, and trustworthy — this is a health application handling sensitive patient data. What I already have: Vercel Pro account — ready to connect Supabase account — ready to create new project GitHub repository — connected and available Domain: fullycharted.app — DNS access available Complete bulk export ZIP from Lovable Cloud — all tables as CSV/JSON, all storage files, complete supabase/migrations/ folder 2 beta users currently — minimal data to migrate Mac computer for local development setup The application: React/TypeScript frontend with Vite and TailwindCSS Supabase backend — PostgreSQL, Row Level Security, Edge Functions, Storage buckets Supabase Auth for authentication 1,326 automated tests passing Currently hosted on Lovable Cloud fullycharted.app currently points to a separate landing page — needs to point to the full app after migration What I need done: Connect GitHub to my Vercel account and configure build settings for Vite/React and all environment variables Create new Supabase project in my account — run supabase db push using migrations folder, import all table data from CSV/JSON export, re-upload all storage files (lab documents, imaging, diagnostic studies), verify all Row Level Security policies working correctly Configure all environment variables — VITE_SUPABASE_URL, VITE_SUPABASE_PUBLISHABLE_KEY, VITE_ADMIN_EMAIL, and any others currently in Lovable DNS configuration — point fullycharted.app to Vercel, configure www redirect, verify SSL certificate Handle 2 beta user accounts — coordinate password reset timing before DNS cutover Full verification — app loads at fullycharted.app, login works, patient data intact, emergency view works without auth, file uploads work, admin route gated correctly, all 1,326 automated tests pass, RLS verified (no cross-account data access) Claude Code setup on my Mac — install Node.js, install Claude Code CLI, clone repository locally, configure local environment variables, verify app runs locally (npm run dev) and tests pass (npm test), walk me through one simple change so I understand the workflow Documentation and handoff — all environment variables documented, Vercel and Supabase configuration documented, local development workflow documented, GitHub push triggers Vercel deployment confirmed Security requirements: This is a health application. RLS policies must be verified after migration. Patients must only access their own data. Admin route gated to one specific email. Public emergency routes work without exposing other patient data. What I will provide: Access to my Vercel account Access to my Supabase account Complete bulk export ZIP GitHub repository access Domain registrar access for DNS Anthropic API key for Claude Code Quick responses throughout the project Success looks like: fullycharted.app loads the full application Beta users can reset password and log in with all data intact All 1,326 tests passing I own all infrastructure completely Claude Code installed, configured, working Complete documentation in my hands Follow-on work: I have a second application (MySynapse — homeschool platform) on the same stack needing the same migration in 1-2 months. Strong performance here leads to that second project directly. To apply please include: Examples of similar Lovable/managed platform to Vercel migrations Supabase RLS and migration experience Your approach to data integrity verification Confirmation you are comfortable with health app security requirements

Convert a 32-page WORD document to a single HTML page. The document is a user guide for a desktop application. The application launches the HTML page from a “Help” link on its file menu. The document consists of 11 chapters each having one to six sub-headings. There are 60 screen-shot images and approximately 6000 words. Since the application is often used absent an Internet connection, fonts should be embedded. There are no external hyperlinks. However, there are many internal hyperlinks. The application launches the HTML page in an 800-pixel wide window in a headless browser. However, it is possible that the window will open to the full width of a user’s screen. The page need not be responsive to mobile browsers however the content layout should not become distorted by different size windows. Two important goals of the project: 1. Create navigation to any chapter that is accessible from anywhere in the document. That could be a floating navigation bar or a repeating navigation DIV at the top or bottom of every page. 2. Approximately match the color scheme of the desktop application or create an attractive contracting color scheme. Possible follow-up projects include: 1. Translating the design to pages on the company’s Website. 2. Translating the design back into the printed document 3. Generating content and designs for other of the company's product literature

I have a book cover in Canva that I'd like to convert to HTML/CSS so I can re-use it for different books and create them programmatically. It needs to match the existing one perfectly.

We have a Figma deaign file we need integrated into an existing website. It consists of five pages with both desktop and mobile views. We’d like these pages coded, potentially using pagefly for future management. This should be a straightforward task. Detailed instructions and figma files will be provided. This is somewhat time sensitive so looking to have this completed quite soon.

I’m building the final UX surfaces for a July 1 SaaS launch and need a fast, reliable React + Supabase engineer who can execute clean, production‑ready screens and flows. The project is front‑end heavy, well‑defined, and focused on UI polish, dashboards, forms, and simple Supabase integrations. You’ll work directly with me (the founder) in a clear, async workflow with daily check‑ins. I move quickly, communicate clearly, and provide detailed requirements for each screen or flow. What I need built Dashboard_flows - user dashboards, scoring views, operator tools UX_surfaces - responsive screens using React, TypeScript, Tailwind Form_and_flow_logic - multi‑step flows, validation, state handling Supabase_integration - basic CRUD, auth, RLS‑safe queries Admin tools - simple internal views for data visibility UI polish - spacing, alignment, loading/error states Stripe_integration - light subscription or billing touchpoints This is not deep backend work. It’s clean, fast UI execution. How I work Clear requirements - I provide detailed specs for each screen Async- updates - daily check‑ins, async communication Fast iteration - I respond quickly and unblock immediately Direct founder access - no layers, no bureaucracy What I’m looking for React Typescript experience Tailwind UI polish Supabase familiarity Stripe comfort Clean communication US based Timeline & budget Start today 2 to 3 week contract 45 to 70 hr Potential ongoing work If you can start immediately and have examples of polished React/Tailwind work, I’d love to see your GitHub or recent projects.

****IMPORTANT PROJECT UPDATE We have refined our technical requirements to save time and eliminate design overhead. Please read carefully before applying: Mandatory WeWeb Experience: You must have direct, hands-on experience working inside the WeWeb platform. Do not apply if you only work in Figma. You must know how to navigate WeWeb's visual style editor, global variables, and UI component kits on day one. No Figma Workflow: We are skipping the expensive, multi-week Figma wireframing process. Your job is to select and configure a premium layout structure (including the left-hand navigation sidebar) directly using WeWeb’s native UI frameworks and components. AG Grid Core Focus: The core of this application relies on an embedded AG Grid component handling massive amounts of high-density compliance data. You must be able to write precise visual specifications (typography for decimal alignment, custom cell styling for editable vs. static cells, row padding, and line weights) that integrate seamlessly into the WeWeb frontend. If you have never shipped a project inside WeWeb or styled high-density financial data tables, this is not the right fit for you. We are transforming a heavy, data-dense financial projection application into a modern enterprise SaaS product. The application architecture is fixed: Supabase (backend), WeWeb (frontend shell), and AG Grid (embedded via WeWeb for high-density tables). The exact columns, calculation tabs, and formulas match state compliance templates and cannot change. This application is primarily a read-only presentation of complex calculations based on defined constraints. Users will not do bulk inline cell editing; only a handful of specific constraint cells will be editable. We need a specialized consultant to select the pre-built design system, define the visual implementation rules for our data grids, and keep our development team visually on track. Scope of Work Tailwind Template Selection Audit our current platform layout and data sheets. Research the commercial market and select a pre-built, enterprise-grade Tailwind CSS dashboard template (e.g., Tailwind UI or equivalent) that handles deep vertical navigation and complex text data out of the box. Present 2–3 live, working template examples for final selection. AG Grid Visual Specification Write a precise visual configuration guide for our developers to apply to the embedded AG Grid component inside WeWeb. Recommend and define the exact typography engine and font pairings optimized for clean, high-density financial data rendering and decimal alignment. Specify exact cell row padding, line weights, and a muted financial color palette to clean up the interface. Define the look for static data cells versus the handful of editable constraint cells so the user instantly knows what can be modified. Developer Implementation Audit Act as the design supervisor. Review the live staging site built by our developers in WeWeb. Provide explicit, pixel-level punch lists ensuring the team accurately executes the template typography, spacing, and grid tokens. Requirements Proven portfolio featuring high-density B2B SaaS dashboards, FinTech platforms, or data-heavy analytical software. (No generic marketing or e-commerce sites). Deep technical familiarity with Tailwind CSS utilities and the visual constraints of AG Grid. Ability to deliver clean visual specifications directly to an engineering team without unnecessary Figma overhead.
