I have a complete, authoritative Figma prototype for ConAcc4—our patent-pending, AI-assisted QA/QC accountability platform aimed at construction projects. Every screen, workflow, and interaction is locked, so the task in front of you is pure engineering: turning that design into a production-ready web portal plus companion mobile apps for both iOS and Android. The system divides naturally into two user experiences. Field technicians need a mobile app that lets them execute checklists, capture photos, work offline, and sync once connectivity returns. Owners, contractors, insurers, and other subscribers log in through the web to view live QA/QC status, analytics dashboards, and automatically generated reports. Because of our IP position, all work will be performed under a signed NDA, and ownership of the source code and associated assets remains with me. UI-only or Figma-only specialists will not be considered; I’m looking for a seasoned development team capable of full-stack delivery, CI/CD setup, and post-launch support. Deliverables I expect: • Production-grade web application aligned pixel-perfect to the Figma prototype • Native (or high-performance cross-platform) iOS and Android apps published to TestFlight / internal testing tracks • Secure backend, authentication, and data model that supports offline field work and real-time web updates • Automated test suite, build pipeline, and deployment documentation • Handover package containing source code, infrastructure scripts, and brief technical documentation Show me examples where you have shipped similar multi-platform products, especially in construction tech or compliance workflows, and outline your proposed tech stack and timeline in your bid. Here is a link to the NDA (Non Disclosure Agreement) it has instructions so please follow them. Once signed I will send an RFP for the prototype. Thanks for your interest and look forward to connecting. https://1drv.ms/w/c/2354008BFA3916F4/IQCnITUwhLA9T72f_-zbvrmUAR3LNNVKyaLMHsfxUJy6Wuc?e=JbLgRQ
