I am looking for a senior AI / full-stack engineer to build a private, conversational AI system for security vulnerability analysis, including a simple but effective web-based user interface. ** A Non-Disclosure Agreement (NDA) must be signed before any technical details, credentials, or access are shared.** This project involves building a tool-using, multi-model conversational AI system, not a basic chatbot. ⸻ High-Level Goal The goal is to build a web-based conversational AI assistant that allows me to: • Upload source-code repositories as .zip files • Chat continuously with the system about the uploaded code • Ask follow-up questions naturally • Receive consolidated, reviewed vulnerability analysis From the user’s perspective, this behaves like a single intelligent AI assistant. Internally, it is a multi-step, multi-model orchestration system. ⸻ Core Requirements 1. Web User Interface (UX) The system must include a minimal but usable web UI, such as: • Chat-style interface • ZIP upload (drag & drop) • Display of analysis progress • Structured responses • Session-based conversation history • Ability to reset or start a new analysis session Visual polish is not the priority; clarity and usability are. ⸻ 2. ZIP Handling & Local Code Processing • Upload .zip archives via the UI • Securely extract and process code locally on the backend • Navigate full repository structures • Select and pass relevant files to LLMs as context AI models do not unzip or execute code directly. ⸻ 3. Conversational AI (Persistent Chat) • Continuous, stateful chat sessions • Context-aware follow-up questions • Conversation memory per session • Each user message triggers a new analysis cycle ⸻ 4. Multi-Model Orchestration (Per Message) For every user message: 1. Claude Opus 4.5 • Primary analysis and hypothesis generation 2. Gemini Pro 3 (Custom Gem Configuration) • Secondary analysis using my existing Gem setup 3. Claude Opus 4.5 • Final review, consolidation, and response generation The backend controls: • context selection • prompt construction • data flow between stages Claude must be able to pass full relevant code context and intermediate analyses to Gemini via the orchestration layer. ⸻ 5. Tool Usage & Local Commands • Controlled execution of local analysis tools (sandboxed) • Models decide what to analyze; backend executes ⸻ 6. Privacy & Security • Secure handling of API keys • No unintended data persistence • Sandboxed command execution • No training on user data ⸻ Technical Expectations • Python backend (FastAPI preferred) • Simple frontend (React / [login to view URL] or similar) • Clean modular architecture • Well-documented code • Basic logging and error handling ⸻ Required Skills • Full-stack experience (backend-heavy) • Strong Python backend skills • Experience with LLM APIs (Claude, Gemini, etc.) • Agent-based or tool-using AI systems • Secure file handling and sandboxing ⸻ Deliverables • Working web-based AI system • Backend + frontend source code • Setup and deployment documentation • Architecture overview • Example usage scenarios Budget Expectations Depending on experience, robustness, and UX quality.

Hi jnr777, Your project vision is genuinely impressive, building a high-fidelity orchestration layer for Security Vulnerability Analysis that leverages a multi-model 'Sandwich' architecture (Claude-Gemini-Claude) is the correct way to mitigate hallucinations and capture deep-logic flaws in source code. To develop a secure, private, and stateful conversational AI system that orchestrates Claude and Gemini to perform deep-tier security audits on uploaded codebases. Core Strategy: --> Multi-Model Orchestration: Implementing a three-stage 'Audit-Review-Consolidate' pipeline for maximum accuracy. --> Active Tool-Usage: Enabling the AI to execute local static analysis tools within a secure sandbox to verify findings. --> Privacy-First Design: Ensuring zero training on data, secure API handling, and temporary local file extraction with automatic cleanup. --> Stateful Context: Maintaining a continuous conversation loop where the AI remembers previous code blocks and follow-up questions. I focus on "Agentic Precision." In security, a general LLM response isn't enough. By building a backend that manages the "Handshake" between Claude and Gemini, I provide you with a tool that doesn't just chat about code, it deeply analyzes it like a human security researcher. I am available to sign the NDA right now. Once signed, I can provide a Technical Architecture Diagram for the multi-model data flow. Please send the document over, and we can proceed. Regards, Atta

HI, there. I fully understand what you need. Success depends on safe zip handling plus sandboxed tool execution so the multi model pipeline stays private and cannot be abused by repo content. Will this run fully in your own environment on a single server or inside your VPC, and do you require user auth or is it single user with session based access only? The major pitfalls which might be appear to perform this project are zip path traversal or zip bomb risks, prompt injection from repo files, leaking API keys in logs, unsafe local command execution, and context selection that misses critical files and produces weak findings. I can build this with a FastAPI backend and a simple Next js UI, with session memory, progress display, and a Claude to Gemini to Claude orchestration per message. You will get a working private system with secure uploads, sandboxed tools, clean modular code, and setup docs and architecture notes exactly as specified. hope to discuss more on chat. best, Danylo.

I specialize in deploying secure, production-grade conversational AI systems, having recently delivered a RAG solution for classified compliance documentation. My background as a Senior AI/Full-Stack Engineer aligns perfectly with building your private security analysis chatbot, prioritizing architecture that ensures strict data isolation and maximum query precision. I approach this as an immediate security necessity, not just an AI project. We will architect this using a robust, self-hosted LLM (e.g., Llama 3 or fine-tuned Mistral) managed via Hugging Face or Ollama for guaranteed data residency and minimal latency. Implementation involves LangChain/LlamaIndex for advanced RAG context indexing across security data. The full-stack build will utilize Python (FastAPI) for the backend processing and a modern JS framework (React/Next) for the secure, authenticated conversational interface, ensuring auditability and enterprise-grade authorization throughout. What are the primary data sources (e.g., SIEM logs, vulnerability reports) that the RAG needs to index? Is the deployment environment fully air-gapped, or will it require secure VPN access? I am available immediately to discuss the architecture constraints and quickly define the MVP scope to ensure a swift, secure deployment.

Hello. You are building a private conversational AI that analyzes uploaded code repositories for security risks through continuous dialogue. The costly failure here is not model quality, but losing context control across sessions and analysis steps. This type of system often breaks when repositories are partially loaded or when model outputs are merged without review boundaries. That leads to confident but incomplete findings, which is worse than obvious errors. This matters because vulnerability analysis must be repeatable and explainable, not just plausible. I would keep each chat message as an isolated analysis cycle, with explicit context selection, staged model handoff, and sandboxed local tools. The UI stays simple while showing progress and preserving session memory without data leakage. Each response is consolidated only after cross-model review. I have handled paid systems where the main task was preventing silent analysis drift under real usage. Before delivery, results are validated through repeat runs to avoid rework or disputes. Once the NDA is signed, alignment can be locked and execution can move forward.
