FFull Stack AI Developer - Build a Complete AI Backoffice Agent for Swiss SMEs Fixed Budget: $550 I am looking for an experienced Full Stack AI Developer to build a complete and functional AI Backoffice Agent for Swiss small and medium sized businesses. The goal is to create a modern business platform that works like a digital office employee and automates administrative workflows. The first target market is Swiss trade and construction companies, including: * Insulation companies * Heating companies * HVAC companies * Ventilation companies * Plumbing companies * Fire protection companies * Other Swiss SMEs The application should be a professional web application and PWA that works on desktop, tablet and mobile devices. 1. Core Concept The software should work like a digital office employee. The user can upload a tender or document and the AI should automatically understand the content, identify relevant work, extract quantities and prepare a quotation. The employee should only need to review the result and approve it. Main workflow: Upload Tender AI analyzes the document Identify relevant positions Extract quantities and units Select positions Calculate prices Create quotation Review quotation Approve quotation Generate PDF The workflow should be simple, fast and highly automated. 2. AI Tender Analysis Users should be able to upload tender documents and specifications, especially PDF files. The AI should read the document and identify relevant positions. Example: Heating insulation - 240 m Cold water insulation - 85 m Ventilation insulation - 160 m2 Fire protection - 24 units Sheet metal cladding - 110 m2 The AI should extract: * Description * Quantity * Unit * Relevant technical information The information should be displayed in a structured and editable format. 3. Position Selection After the AI analyzes the document, the user should be able to select which positions should be included. Example: Heating insulation - 240 m Ventilation insulation - 160 m2 Sheet metal cladding - 110 m2 The user should then be able to click: Create Quote 4. Company Price Database Each company should have its own price database. Example: Heating insulation: CHF 45 per meter Ventilation insulation: CHF 60 per m2 Sheet metal: CHF 85 per m2 The AI should use the company's prices when calculating the quotation. If a price is missing, the system should clearly show that the price needs to be entered. The AI must not invent important prices. 5. Automatic Quote Creation The system should automatically create a professional quotation. The quotation should include: * Company logo * Company information * Customer information * Project * Quote number * Date * Position descriptions * Quantities * Units * Prices * Subtotal * VAT * Total * Payment terms The quotation should be generated as a professional PDF.

A project should contain: * Customer * Project name * Project address * Documents * Quotations * Orders * Invoices * Notes * Status Example: Project: New Building Zurich Customer: Muster AG Status: Quotation Tender.pdf 8. Invoice System The platform should include invoicing. Users should be able to create an invoice from a quotation or order. The invoice should automatically inherit: * Customer * Project * Positions * Prices * VAT * Company information Invoices should be generated as professional PDFs. The system should support CHF and Swiss VAT. The architecture should be prepared for Swiss QR bills. 9. Voice Commands The platform should support voice commands. Example: "Create an invoice for Muster AG for 5 hours at 85 francs per hour." The AI should understand the command and create an invoice draft. Another example: "Add 30 meters of heating insulation at 45 francs per meter." The system should add the position. Another example: "Create a quotation for Muster AG for 120 meters of heating insulation." The system should create the quotation. Important actions should be reviewed before being finalized. 10. Dashboard The platform should include a professional dashboard. It should show: * Customers * Projects * New quotations * Open quotations * Accepted quotations * Orders * Open invoices * Overdue invoices * AI actions * Recent activity 11. Approval System The AI should prepare important actions for the user.

Web Application and PWA The application should be responsive and work properly on: * Desktop * Laptop * Tablet * iPhone * Android The application should be installable as a PWA. The architecture should allow future native iOS and Android development. 13. Swiss Market The platform is specifically designed for Swiss companies. It should support: * CHF * Swiss VAT * Swiss company information * Swiss addresses * Swiss date formats * Swiss quotation structure * Swiss invoice structure * QR bill ready architecture 14.

Security The platform should use secure architecture.

Technology I am open to the developer's recommendations. Possible technologies include: * Next.js * React * TypeScript * PostgreSQL * OpenAI API * PDF and OCR processing * Speech to text * Vercel or equivalent hosting The system should have a clean and scalable architecture. 17. User Experience The application should be modern, clean and easy to use. The goal is to minimize manual work and the number of clicks. A typical user should be able to: Upload a tender Let the AI analyze it Review extracted positions Select positions Apply company prices Generate a quotation Review it Generate the final PDF The entire process should feel simple and fast. 18. Complete Core Workflow The most important workflow is: User uploads tender AI reads the document AI identifies relevant work AI extracts positions AI extracts quantities and units User selects positions AI uses the company's price database System calculates the quotation System creates the quotation System generates the PDF User reviews the quotation User approves the quotation The customer, project, quotation and invoice data should all be connected. 19.
