About this gig
Standard web forms feel outdated, and generic AI plugins look clunky on custom websites. Without a clean, embedded AI interface connected to your model, site visitors disengage and SaaS prototypes fail to convert users. I engineer responsive Next.js and React AI web applications, custom ChatGPT wrappers, and embedded web widgets that connect directly to OpenAI APIs or custom LLMs with modern UI/UX.
How the System Works:
- Next.js & React Frontend: Blazing-fast, mobile-responsive UI built with Tailwind CSS.
- OpenAI & API Integration: Secure server-side API calls to GPT-4o, Claude, or custom models.
- Embedded Web Widgets: Clean iFrame or JS embeds for any site (WordPress, Webflow, Shopify).
- Backend Webhook Sync: Connects frontend user inputs with n8n, Supabase, or CRM backends.

Hello, I’m Elowen Hawkworth. As a lead systems engineer, I design fault-tolerant backend infrastructure, custom API integrations, and scalable business process automation systems. Rather than relying on fragile, basic scripts that fail under heavy data loads, I build resilient enterprise pipelines utilizing n8n, Make, Zapier, Microsoft Power Automate, and GoHighLevel. My core focus is eliminating operational friction, syncing complex CRM architectures, and transforming manual workloads into reliable, self-sustaining engines for growth. Let's build.

FAQ
What tech stack do you use to build AI web applications?
I build modern frontends using Next.js, React, TypeScript, and Tailwind CSS, connected securely to backends like OpenAI API, Anthropic Claude, Vercel, or Node.js.
What is a ChatGPT wrapper and how does it work?
A ChatGPT wrapper is a custom web interface tailored to your specific niche that uses the OpenAI API under the hood to process prompts, generate content, or answer user questions with custom styling.
Can this AI web app or widget be embedded into my existing website?
Yes. I can deliver the solution as an easily embedded widget, script, or iframe that works on Webflow, WordPress, Shopify, Framer, or custom HTML sites.
Is my OpenAI API key secure when using this web application?
Yes. All API calls are processed securely on the server side (via Next.js API routes or serverless functions) so your private API keys are never exposed on the client side.
Can the AI web app stream responses in real-time like ChatGPT?
Yes. I can implement response streaming (Server-Sent Events) so answers appear word-by-word instantly for a fast user experience.
Do I need my own OpenAI or AI provider account?
Yes. You will need an active OpenAI API account (or account with your chosen AI model provider) to generate your secret API key.
Can the frontend pass user data to external CRMs or webhooks?
Yes. I can configure backend endpoints or n8n webhooks to capture user inputs, lead data, or generated results and route them to your CRM or database.
Do you test the AI application on mobile and desktop screens?
Yes. I conduct full cross-device testing to ensure the frontend interface is responsive, fast, and bug-free across all screen sizes.
