    Hello Alexander.

    I have experience deploying projects on AWS services. I have extensive experience writing CI/CD pipelines for automatic updates from your repository on GitHub or GitLab. I am well acquainted with Docker, using it in all the projects I am involved in. I have experience using Google Vision API. I have extensive experience working with OpenAI API, Claude, and other AI services. I have experience writing applications that work/process images, Text-to-video, text-to-voice, etc. I have over 5 years of experience with REST APIs and websockets on large projects, primarily in American companies.

    For the backend, I recommend using FastAPI - asynchronous out of the box, this feature will be useful as we will need to make many requests to third-party services. Database - PostgreSQL, for websockets - Redis, and if necessary, we will connect ElasticSearch. Frontend - React will be the ideal choice for your project. If needed, we will connect Redux for normalizing state management, if required. I am ready to answer all your questions.

    Best regards,
    Georgy
    Senior Python Developer

    Hello, Oleksandr! 🌟

    My name is Semen, I am a specialist with many years of experience in developing backend systems, particularly LegalTech platforms, focusing on AI integration and GDPR compliance. I am ready to develop an MVP LegalTech platform for checking AI products for GDPR compliance within 6–8 weeks.

    📋 Implementation Plan:
    User data intake:
    I will implement FastAPI endpoints for uploading the description of the AI product (text or PDF/DOCX file).
    I will use the PyPDF2 and python-docx libraries for file parsing.
    Integration with OpenAI GPT-4 and LangChain:
    I will set up integration with the OpenAI API (GPT-4) for analyzing the text of the AI product.
    I will use LangChain to create a processing chain: extracting key aspects of the product and comparing them with GDPR requirements (based on pre-prepared prompts).
    Generation of the legal report:
    The report will be generated in PDF format (using reportlab) and API response (JSON).
    The report will include: GDPR compliance, identified risks, recommendations.
    GDPR compliance:
    Data will be stored in the EU (Supabase/Hetzner).
    Data encryption at rest (AES-256) and in transit (TLS 1.2+).
    Logging requests without storing personal data.
    I will set up a data deletion mechanism upon user request (GDPR Article 17).
    Architecture and stack:
    FastAPI for REST API.
    PostgreSQL for the main database (Supabase).
    Redis for caching requests to the OpenAI API.
    Backblaze S3 for file storage (PDF/DOCX).
    Logging via logging and monitoring via Prometheus (optional).
    💻 Sample code for MVP:
    A sample implementation of the core functionality of the backend system is provided in personal messages.

    💰 Estimated cost:
    MVP development (6–8 weeks): 120,000 UAH.
    Infrastructure setup (Supabase/Hetzner, Backblaze): 5,000 UAH.
    Support: 10,000 UAH/month (optional).

    ❓ What’s next:
    We will discuss the details (report structure, prompts for LangChain).
    I will provide access to the testing environment.
    I am ready to start immediately! 🚀 I look forward to your feedback.

    Best regards, Semen 😊
