Operating as a critical technical asset, you will own this project end-to-end, single-handedly taking a visionary product concept and turning it into a functional, deployment-ready web tool. - Build a web-based tool capable of mapping room and floor-plan layouts directly from a mobile camera (utilizing ARKit / RoomPlan, ARCore, WebXR, or a comparable approach). - Capture live or uploaded video to record layouts, square footage, and individual rooms. - Translate captured data into clear floor-plan visualizations usable for heating and cooling load estimates. - Build a structured backend holding comprehensive HVAC asset data, unit histories, and technical specifications. - Capture and identify model numbers, serial numbers, and asset tags from photos or video (integration of cloud OCR / vision services is highly welcomed). - Develop an automated reporting module that compiles captured asset data into a polished client deliverable outlining three distinct preventive maintenance or replacement schedule options. - Implement secure authentication and role-based access controls for technicians, sales reps, and admins. - Conduct extensive testing, debugging, and quality assurance workflows to harden the application to a client-ready standard prior to deployment. Qualifications - 3 to 5+ years of professional full-stack web development experience. - Proficient in a modern web stack (e.g., React / Next.js / Node or equivalent), structured database backends, and REST / API integration. - Hands-on experience with camera / AR / spatial tools (RoomPlan, ARCore, WebXR, photogrammetry) and/or image recognition and OCR (cloud vision APIs) is strongly preferred. - A strong, verifiable portfolio demonstrating prior full-stack projects, interactive web tools, mapping projects, or database-driven applications. - A degree in computer science / engineering or equivalent demonstrable skill.
