I'm building a web app for heavy industry in the pacific northwest. I've made a good start using claude code, but it needs a professional to finalize. See PRD for additional details. "Enviroconnect" (placeholder name) is a curated B2B marketplace where Pacific Northwest industrial facility managers discover, vet, and engage pre-qualified environmental compliance vendors; without cold calls, Google searches, or sales pitches. It is the only platform that combines vendor discovery, environmental compliance specialization, trust-based vetting, and workflow tools (RFQs, messaging, scheduling, reviews, compliance docs, etc.) at a price point accessible to mid-market facilities.

Professional Auto Appraisals is seeking an experienced full-stack developer to add a customer onboarding portal to our existing appraisal management application. Important: We already have a working claim management/tracking system. We are not looking for a new CRM, dashboard, or claim management platform. This project is to extend our existing application and automate the client onboarding process. Developer must be comfortable reviewing and modifying an existing codebase. This is not a greenfield project. The selected developer will be extending an existing appraisal management application and integrating new functionality into the current architecture. Project Goal Create a customer-facing portal that allows a client to: * Submit claim information * Upload documents * Complete required agreements * Sign documents through DocuSign * Pay online * Automatically create a claim in our existing application after onboarding is complete Required Workflow Step 1 - Customer Intake Customer completes an online intake form from our website. The form should collect: * Name * Email * Phone number * Address * Insurance carrier * Claim number * Adjuster information * Vehicle year, make, and model * VIN * Mileage * Settlement offer amount * Lienholder information * GAP coverage information * Vehicle photos * Insurance valuation report * Supporting claim documents Step 2 - Document Generation The intake information should automatically populate our existing document templates: * Appraisal Agreement * Letter of Authorization * Right to Appraisal Request (if applicable) Step 3 - Embedded DocuSign Signing We already have a DocuSign account. Requirements: * Use the DocuSign API * Use embedded signing directly within the website/application * Auto-populate templates with intake information * Obtain signatures on the Appraisal Agreement and Letter of Authorization * Return completed documents to the application Step 4 - Online Payment After signing is complete, the customer should pay online. Requirements: * Stripe integration preferred * Payment confirmation stored in the application * Failed payment handling * Receipt generation Step 5 - Claim Creation A claim should only be created in the production claim tracker after: * Required documents have been signed * Payment has been successfully received Once those conditions are met, the system should: * Create a new claim record in the existing application * Attach all intake information * Attach uploaded files * Attach signed PDFs * Set initial status to: "New Intake - Paid" Optional Lead Tracking Prior to payment, the system may maintain a temporary lead record for incomplete or abandoned submissions. These records should not appear as active claims in the production claim tracker. File Storage The system should: * Store uploaded files securely * Store signed PDFs * Associate all files with the claim record * Google Drive integration is preferred if practical with the existing application architecture Technical Requirements Experience with: * Existing application integrations * React * Node.js * Replit deployments * PostgreSQL or similar databases * DocuSign API * Embedded DocuSign signing * Stripe integration * Webhooks * Secure file uploads * Google Drive API * Mobile-responsive interfaces Deliverables * Customer intake portal * Document automation * DocuSign integration * Payment integration * Automatic claim creation * File upload and storage * Status automation * Documentation for future maintenance When applying, please provide examples of: * DocuSign API projects * Embedded signing implementations * Stripe integrations * Workflow automation projects * Applications integrated into existing systems rather than built from scratch The ideal developer understands API integrations, workflow automation, and extending an existing application without replacing current functionality. The ideal candidate is someone who's built: SaaS applications Customer portals Payment workflows E-signature integrations Not someone whose experience is primarily brochure websites or WordPress sites.

WHO WE ARE LOOKING FOR We are a digital strategy firm managing website builds for B2B clients. We are not looking for a one-off hire — we are looking for a reliable WordPress developer or small team to become our go-to partner for an ongoing pipeline of work. This posting is for our first project. We have three additional similar projects coming in the next few weeks, all with the same profile: React prototype to WordPress conversion, custom interactive components, deployment to client hosting. If this first project goes well, we will bring you all of them. After each launch, we expect ongoing maintenance and update work on a per-project basis. If you are looking for a single project, this is not the right fit. If you want a consistent source of well-specified work with a team that communicates clearly and pays on time, read on. THE PROJECT We have a fully designed and approved React/Vite website prototype for a B2B commercial services company. The design is finished and client-approved. We need it converted into a production-ready custom WordPress theme and deployed to the client's hosting account (GoDaddy or SiteGround). This is a conversion project, not a design project. Your job is to build what already exists in the prototype — exactly as it looks, exactly as it behaves. No design decisions required from you. Full technical documentation including the prototype URL, page specifications, and a detailed component spec will be shared with qualified applicants after an initial screening conversation. SCOPE The site is 15 pages. The most complex component is an interactive Google Maps portfolio map showing 400+ real project locations with marker clustering, state-level shading, a filter panel, and a click-to-expand project detail view. There is also a multi-step JavaScript ROI calculator on the homepage that must be rebuilt with full functional parity. The theme must be a fully custom WordPress theme — no Elementor, no Divi, no WPBakery, no page builders of any kind. The client needs to make basic text edits through Gutenberg without breaking the design. Advanced Custom Fields or equivalent is required for structured content. You will also handle deployment: WordPress install, theme setup, DNS coordination, and go-live confirmation on the client's hosting account. TECHNICAL REQUIREMENTS The site must hit a PageSpeed mobile score of 75 or higher. Google Fonts must be self-hosted — not loaded from the CDN. Images must be served in WebP with proper srcset. The Google Maps script must load asynchronously and only on the portfolio page. The design uses sharp corners throughout (border-radius zero) and a specific color system that must be preserved exactly. Every page needs individually configurable meta titles, meta descriptions, and Open Graph tags. The theme must be compatible with Yoast SEO or Rank Math. ONGOING RELATIONSHIP After each project launches, we will bring you maintenance and update work on a per-request basis — content updates, new pages, plugin updates, client revisions. We scope and pay per request, no retainer required. We are looking for someone who wants to be our first call, not a one-time vendor.
