Backend Developer Needed: Build Lightweight API + Static Site Builder + GHL Integration for NuRevur Impact Engine Project Summary NuRevur is building a lightweight backend service (“Impact Engine”) that connects: GoHighLevel (GHL) Gemini FlashLite (AI content generation) Static HTML templates A simple PWA (manifest + service worker) NuRevur’s proprietary workflow logic (PA‑OS) This backend receives structured data from GHL, calls Gemini to generate content, injects that content into templates, builds a static website + PWA, deploys it, and sends the results back to GHL. This is not a full SaaS platform. This is a small, clean Node.js backend with 2–4 endpoints and a static site builder. What You Will Build You will implement a small Node.js/Express backend that performs the following: 1. Receive webhook requests from GHL Triggered by: Tag applied Pipeline stage change Form submission Custom field update Payload includes nonprofit data and a return webhook URL. 2. Call Gemini FlashLite (AI) using provided prompts You will: Use provided prompt templates Send nonprofit data to Gemini Receive structured JSON (website content + outreach emails) No prompt writing required. 3. Render static HTML pages using provided templates You will: Inject JSON content into HTML templates Apply branding colors Generate: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] Templates are provided. 4. Generate PWA assets You will: Render [login to view URL] from template Render [login to view URL] from template Templates are provided. 5. Build a static site bundle Output structure: Code /dist/{job_id}/web /dist/{job_id}/pwa 6. Deploy the static site You will implement a simple deploy function that uploads the static bundle to a hosting provider (Netlify, Vercel, Cloudflare Pages, or similar) and returns: website_url pwa_url 7. Send results back to GHL You will: Call the GHL return webhook Update contact fields Add notes Optionally move pipeline stages Endpoints to Build POST /nu-revur/website-preview Accepts nonprofit data Calls Gemini Builds website + PWA Deploys Sends results to GHL POST /nu-revur/outreach-sequence Accepts nonprofit data Calls Gemini Returns outreach email + follow‑ups Sends results to GHL GET /health Simple health check Tech Stack Node.js + Express TypeScript Static HTML templates Lightweight PWA (manifest + service worker) Any static hosting provider (Netlify/Vercel/Cloudflare Pages) No frontend frameworks. No database required (simple in‑memory job store is fine). No complex infrastructure. What We Provide You will receive: Full folder structure All file stubs All prompt frameworks All HTML templates All PWA templates Full architecture blueprint Full workflow logic GHL integration instructions You are not writing prompts, templates, or architecture — only implementing the backend. Deliverables Fully functional backend deployed to a public URL Working /health endpoint Working /nu-revur/website-preview endpoint Working /nu-revur/outreach-sequence endpoint Static site builder working end‑to‑end PWA generation working end‑to‑end Deployment function returning URLs GHL workflow connected and tested Successful test run with one nonprofit Ideal Developer Strong with Node.js + Express Comfortable with TypeScript Experience with static site generation Experience with webhooks Experience with external API integrations Experience deploying small backend services Comfortable assembling code generated by an AI model This is a small, well‑defined project—perfect for a developer who likes clean architecture and fast execution. Project Size This is a 4–6 hour build for a competent developer. How to Apply Please include: Your experience with Node.js/Express Your experience with static site generation Your experience with API integrations Your preferred hosting provider Your estimated timeline

Hello, I’m an experienced Node.js and TypeScript developer with a focus on clean, maintainable backend services. I have built multiple lightweight APIs that integrate with third-party services, render static sites, and handle webhook-driven workflows—projects very similar in scope to the NuRevur Impact Engine. Relevant Experience: Built webhook-driven Node.js/Express backends that receive structured data, process it, and push results to external CRMs. Developed static site generators using HTML templates and JSON content injection, including PWA support (manifest + service worker). Integrated external APIs with structured payloads and managed deployment pipelines to Netlify and Vercel. Implemented lightweight in-memory job tracking and ensured reliable response handling for asynchronous workflows. For this project, I would: Implement /nu-revur/website-preview and /nu-revur/outreach-sequence endpoints in TypeScript with full error handling. Generate static HTML pages and PWA assets from templates with branding applied. Hosting & Deployment: I recommend Netlify for simple static hosting, automated builds, and reliable PWA support. Timeline: With provided templates and architecture, I can deliver a fully functional backend—including endpoints, static site generation, PWA, and GHL integration—within 1 business day (4–6 hours) for initial testing. Looking forward to contributing to NuRevur’s Impact Engine. Best regards,

Your spec is extremely clear - this is a clean backend build, not a SaaS platform. A few endpoints, GHL webhook handling, Gemini integration, template rendering, and static deployment. Straightforward Node.js/Express work. For deployment, I'd wire up Vercel or Netlify - both have clean APIs for deploying static bundles programmatically, which keeps this lightweight as intended. The GHL webhook flow and Gemini API calls are standard stuff I've done before. With all templates provided, I can deliver this in under a week. Happy to start immediately. - Usama

Hi NuRevur team, your plan to connect GoHighLevel, Gemini FlashLite, static templates, and a simple PWA into a compact Impact Engine is exactly the kind of outcome I deliver. This is my speciality: turning integration needs into a clean, reliable backend that accelerates time-to-value and reduces risk. I'm Iosif Peterfi, 15+ years delivering robust web backends and CMS work from Berlin. I partner with PMs to keep scope tight, milestones clear, and business value front and center, with calm, decisive execution. I will deliver a lightweight backend that cleanly handles 2-4 endpoints to receive GHL webhooks, trigger content generation via Gemini, render the provided templates, produce a static site plus PWA assets, deploy to a hosting provider, and report back with site URLs. The flow will be simple to test, with a small in-memory store for jobs, a health check, robust error handling, and retry logic to minimize risk. You'll get a complete dist structure for web and pwa, a deploy function, and end-to-end testing aligned to your GHL workflow. I'll keep the rollout steady, with milestones for webhook integration, content rendering, bundling, and deployment. Last quarter I helped a nonprofit campaign team automate landing pages by combining AI content with a templated site. We cut production time from days to hours and reduced branding inconsistencies.

Hello, I understand you’re looking for a lightweight Node.js/Express backend to handle GHL webhooks, generate content via Gemini FlashLite, build static sites and PWAs, deploy them, and return results to GHL. I can implement fully functional endpoints (`/website-preview`, `/outreach-sequence`, `/health`) using TypeScript, inject JSON into provided HTML templates, generate manifest and service-worker files, and handle deployment to your chosen hosting provider. My approach ensures a clean, maintainable architecture with in-memory job tracking, accurate integration with GHL webhooks, and fully automated static site/PWA generation. The backend will be fully tested with one nonprofit to verify end-to-end functionality and will return live URLs upon deployment. Thanks, Asif
