Hello, I can build your web-based heating design + heat-loss calculation platform with an interactive 2D floor-plan editor, a robust backend, and a standards-aligned calculation engine. I’ve developed complex web editors (Canvas/SVG) with real-time computation and versioned project storage, so this scope is a good fit. Proposed architecture . Frontend: React + TypeScript with Canvas/SVG rendering (zoom/pan, grid snapping, drag handles, multi-select, copy/paste, undo/redo). Side panel for element properties, toolbar tools, real-time results, optional dark mode. . Export: PDF/PNG/SVG (DXF via a converter layer or export service depending on requirement depth). . Backend: Node.js (NestJS) or Python (FastAPI), REST or GraphQL, PostgreSQL for projects/users, JWT auth, autosave + project versioning, role/subscription gates (Free vs Pro). . Infra: AWS/GCP/Azure deployment, backups, logging/monitoring. Thermal calculations . Dedicated calculation module implementing EN 12831-style heat loss: rooms/volumes, U-values, temp deltas, orientation/climate zones, ventilation/infiltration assumptions, and sizing recommendations. . Generate downloadable reports with clear inputs/outputs and per-room breakdowns. Best regards, Abdul Hadi

Hello, Project Challenge You need a professional web-based platform that lets users design heating systems visually on a 2D floor plan while accurately calculating heat loss and system sizing, all in real time, without performance issues even on complex layouts. Implementation Strategy I will build an interactive 2D editor using HTML5 Canvas or SVG with a modern framework like React or Vue.js, supporting drag-and-drop room creation, resize handles, zoom/pan, grid snapping, undo/redo, and export to PDF/PNG/SVG/DXF. A secure backend with REST or GraphQL will manage users, projects, autosave, versioning, and subscription tiers using JWT authentication and PostgreSQL or MongoDB. The thermal calculation engine will follow EN 12831 principles, factoring room dimensions, insulation values, temperatures, orientation, and climate zones, with live calculation feedback and downloadable reports. The UI will remain responsive with a clear toolbar, property panel, and optional dark mode, while keeping the code modular and well documented. Delivered Result You will receive a complete, scalable heating design web application with a powerful 2D editor, accurate heat-loss calculations, user management, cloud deployment, full source code, and documentation—ready for professional use and future expansion. Thank you.

Salut, (nu sunt bot!:) Daca vrei o solutie pt calculatorul tau sau pt reteaua ta locala de calculatoare te pot ajuta cu acest proiect sa ai un cost viitor redus spre zero. Daca insa vrei ceva sa ai o varianta monetizata pt cloud ar trebui sa spui exact si ce cloud alegi pt ca aici tine de optiunile tale de cost de productie viitoare si mai putin de partea de programare/dezvoltare. La fel mai poti folosi spre exemplu si o varianta de 2 cloud-uri: unul operational si unul de hosting de access/expunere. Asa ca astept cu nerabdare o discutie cu tine in acest sens! O zi excelenta!
