I run a digital and AI-visibility firm serving commercial real estate and lifestyle development clients. I need a US-based front-end designer-developer to be my go-to for premium website builds. The work is project-based and recurring. I land these regularly and want one exceptional person I can bring in when they do. The bar is high. The sites I sell have to visually beat the best in the category: Downtown Summerlin, Tivoli Village, Santana Row, Avalon, The Domain. I am not looking for someone who installs and customizes themes. I need original design. What you are: A designer first, with the development skill to ship what you design, or a clean Figma-to-build handoff you own Fluent in motion, interaction, and video-forward layouts US-based, for timezone overlap and the occasional client call Comfortable in WordPress when the client needs it, and able to recommend the right stack when they do not What the work looks like: High-end lifestyle retail, mixed-use, and commercial real estate marketing sites Two-state builds: pre-leasing sites that flip to activation sites at opening Immersive, video-forward experiences, store by store Projects with real design budgets behind them I read every answer. Tell me: Two or three portfolio pieces where you did the design yourself. Link the live sites and tell me what was yours. Original design, not theme customizations. Are you a solo designer-developer, or do you design and hand off? If you hand off, how does it work, and have you shipped that way before? Pick one of the sites above. Tell me one thing you would do better. US-based required. Tell me your rate and your timeline for a six to ten page premium build.

We need a developer to analyze, repair, and optimize our SaaS platform. The work includes reviewing the codebase, identifying issues, and improving performance and reliability.

This is a part-time project for someone who can help ensure the platform runs smoothly and efficiently.

OVERVIEW I'm building Inkora, a subscription web app: an AI creative-writing companion for fiction (romance, fan fiction, poetry, general fiction). The React front-end is COMPLETE and will be provided, with clearly marked integration points. I need the backend built, connected, and the full app deployed. This is an 18+ platform with content safeguards. STACK ALREADY IN PLACE - React front-end (provided; single-file app ready to be scaffolded into a project) - GitHub (repo will live on my account) - Vercel (hosting, my account) - Stripe account created - Anthropic (Claude) API key — must live server-side only, never in client code - Domain: inkora.com SCOPE OF WORK 1. Secure AI endpoint — a serverless endpoint (e.g. POST /api/write) that attaches the provided system prompt, calls the Claude API with the server-side key, and returns the text to the front-end. Suggested writing model: claude-sonnet-4-6. 2. Content moderation — screen user input BEFORE the model call and model output AFTER it. Block sexually explicit content and gratuitous graphic gore. Use a inexpensive-model screen (e.g. Haiku) or a third-party moderation API. Log violations; support a warn-then-suspend flow. 3. Auth — your recommendation (Supabase or Firebase preferred). Email + password baseline; Google sign-in if low effort. 4. Database — persist each user's stories (title, genre, full message history, timestamps), characters, and notes. The front-end already models these data shapes. The story's full saved history must be sent with each AI request (this powers in-story continuity). 5. Subscriptions (Stripe) — $10/month, ~$27/quarter, ~$96/year. Free tier: 10 messages per day (make this a config value), resetting every 24h. Gate writing access by subscription status / remaining free allowance. Handle the subscription lifecycle via webhooks. 6. Age-gate persistence — the front-end collects date of birth + an 18+ affirmation; store the affirmation timestamp with the account. Structure it so a third-party age-verification provider can be swapped in later without reworking the flow. I'm open to building on a proven starter/template (e.g. the Vercel AI chatbot template) if it speeds things up — adapting solid existing code is welcome. DELIVERABLES - Deployed, working app (provided front-end + your backend) on my Vercel, repo on my GitHub - All secrets configured as environment variables (never in client code) - Short handoff notes: key rotation, where moderation logs live, how to change config values WHAT I PROVIDE - Complete front-end code, a written backend brief, and the system prompt (shared privately with the selected freelancer) - All accounts (GitHub, Vercel, Stripe, Anthropic) already created and ready TO APPLY, PLEASE ANSWER THESE IN YOUR PROPOSAL: 1. Have you wired Stripe subscriptions with webhooks before? Link or example. 2. How will you keep the API key off the client? 3. How would you implement input + output moderation cost-effectively? 4. Have you deployed serverless APIs on Vercel? 5. Your fixed quote and timeline for this scope. Proposals that don't answer these questions will not be considered.
