Hi, I am a software engineer with over 16 years of experience building desktop applications, AI-assisted document workflows, OCR pipelines, and production-ready systems. I can design LeadPilot as a modular, local-first Windows assistant that automatically indexes project folders, extracts multilingual content, cross-checks EPC/XML and supporting documents, and produces traceable findings with confidence and risk scores. I would begin with the core workflow: project detection, document classification, OCR, structured comparison, Greek AI chat, and PDF reporting. Floor-plan and equipment recognition would then be validated against representative Greek EPC projects, with every result linked to its source so engineers can review it rather than rely on a black box. The complete specification is substantially larger than the listed budget, so I suggest using this bid for a working first-phase MVP and detailed roadmap, followed by agreed milestones for the remaining modules. Which features are essential for the first usable release? I would be glad to discuss the documents, preferred Windows technology, and phased delivery details.

I can help you by architecting this as a modular C# desktop app where each capability is an independent plugin—OCR, floor plan analysis, document comparison, AI chat—communicating through a shared project context rather than one monolithic black box. The project folder workflow you described maps naturally to a file system watcher that triggers a classification pipeline: hash fingerprints for known document types, regex patterns for Greek EPC XML structure, and a lightweight embedding model to sort unknowns into the right buckets. For floor plan analysis, I'd use OpenCV-based contour detection tuned specifically for architectural symbols (walls as thick parallel lines, doors as arc segments, dimension text via OCR bounding box association) rather than a generic vision model that hallucinates. The AI assistant can run a quantized local LLM with a RAG pipeline over TOTEE/KENAK documents, switching to cloud only when explicitly requested for manufacturer research. Devil's Advocate mode is essentially the same pipeline with an inverted prompt and a stricter confidence threshold—not a separate system. Greek-first with a language detection layer that routes documents to the appropriate OCR model and translation step. The real differentiation in my approach is that every analysis result carries a structured evidence trail (source document, page, bounding region, extracted text) so the confidence scores are auditable, which is what actually matters for EPC verification.

★•══•★ Hi client ★•══•★ You need a smart Windows AI assistant to help Civil Engineers with EPC quality control and Exoikonomo project checks—without replacing their expert judgment. I get it: a tool that organizes files automatically, performs OCR on various documents, analyzes floor plans and images, compares reports, and even acts as a Greek-speaking AI chat companion sounds like a game-changer. I’d focus on building a modular desktop app that works offline but updates AI models and libraries seamlessly. The AI will flag inconsistencies, score confidence, and generate clear PDF reports. Multilingual support and internet research add serious value here. I’ve handled complex AI integrations and software architecture before, so delivering clean code with full docs and smooth updates is my priority. How do you envision the “Devil’s Advocate” mode working in tricky scenarios? Best regards, Rico

I understand you're looking for a robust Windows Desktop AI assistant for EPC engineers, similar to how AI is streamlining diagnostics in complex engineering fields today. My experience developing localized, offline-first applications with optional cloud integration makes me confident I can deliver a highly effective solution for your specific needs in Greece. My technical approach will leverage a Python-based backend with a PyQt/PySide GUI for a native Windows feel. For core AI functionalities, I'll explore pre-trained NLP models for document analysis and potentially leverage ONNX Runtime for efficient local inference, minimizing reliance on cloud connectivity. The modular architecture will allow for easy feature expansion, and I'll implement robust local data storage and synchronization mechanisms. To ensure alignment, I'd like to clarify: what specific types of documents will the assistant primarily analyze for quality control, and are there any existing Greek engineering standards or forms that need to be pre-integrated for optimal performance? I'm available for a brief call to discuss these details and how I can best support your project.

A Windows desktop AI assistant for Greek EPC engineers — offline-capable, auto-classifying dropped project files, OCR + floor-plan analysis + multilingual document comparison, and a Devil's Advocate reviewer mode. This is a real product, not a small tool. The hard parts aren't the chat layer — they're the floor-plan geometry extraction, cross-document consistency logic, and keeping the whole thing usable offline while still allowing cloud AI when the engineer opts in. Architecture I'd propose: .NET (WinUI 3) shell for native Windows feel + a modular Python service running locally for the AI pipeline. Document classification via a small local LLM (Llama 3 or Phi) for offline, with an optional GPT-5 / Claude route for heavier reasoning when internet is on. OCR through Tesseract with Greek/Latin/Cyrillic language packs plus a fallback to Azure Document Intelligence for scanned invoices. Floor-plan analysis is a CV pipeline — line/contour detection for walls, YOLO fine-tuned on architectural symbols for doors/windows/rooms, then geometry inference for dimensions and orientation. Component recognition (boilers, heat pumps, PV) is another YOLO model trained on your photograph library.
