    Hello!
    I have reviewed the project https://cab.razmorozka.com/ and your description — I understand the task as creating a full-fledged backend and internal logic for the client cabinet and backoffice.
    What I can do within the project:
    Design and implement the database (PostgreSQL/MongoDB) + NestJS/Express.
    Set up authorization (JWT) and roles: client / operator / admin.
    Implement document upload with automatic saving to Google Drive/Cloud.
    Connect OCR, translation (Google Translate), and verification through your AI API.
    Create a document workflow: statuses, comments, requests for revisions, file versions.
    Develop a user-friendly backoffice:
    a list of clients with progress,
    viewing their documents and Google Drive folders,
    managing access and sections of the cabinet,
    reminders for uploads,
    log of manager actions,
    weekly export to Excel.
    Implement document generation based on templates and collective requests.

    Hello.

    I have reviewed the project razmorozka.com and the description of the required logic. At this moment, it is not just a personal account, but a document management system with a managed workflow, statuses, AI integrations, and increased security requirements.

    I am ready to take on the design and implementation of the internal logic from scratch, including:

    designing the database and access roles

    backend (Node.js / NestJS or Express)

    working with Google Drive (folder structure, access, signed links)

    document processing: uploading, statuses, comments, versions

    integration of AI checks, OCR, and translations

    operator admin panel (clients, progress, tasks, action logs)

    client account with dynamic document requirements

    notifications (email / Telegram)

    data export and reporting

    basic security audit and data access protection

    I see the project as a phased development, starting with architecture and basic workflow, followed by the integration of AI and automation. This approach reduces risks and allows for flexible budget management.

    I work in a B2B format, maintain confidentiality, and am ready to sign an NDA.
    I have experience in developing personal accounts, back-office systems, and projects with sensitive data.

    I am ready to discuss the details of the logic, propose optimizations, and provide a preliminary estimate on timelines and budget after clarifying the requirements.

    Rate is 30 currency units per hour.

    Good day.

    The company ViACore offers the development and implementation of a comprehensive personal account and back-office system for the project razmorozka.com from scratch — including architecture, internal business logic, security, and integrations with third-party services.

    We will send the commercial proposal in private messages.

    I am a full-stack developer (Node.js / NestJS / Prisma / PostgreSQL) with experience in creating client dashboards, admin panels, and document management systems with high security requirements.

    I have carefully studied the technical specifications. The project is clear — it is not just CRUD, but a system with statuses, roles, files, automatic document processing, and back-office logic. I have such experience.

    What I will deliver within the project:
    1. backend logic on NestJS (JWT, roles, RBAC, queues)
    2. database + document statuses, client progress, comments
    3. integration with Google Drive (folders, secure access)
    4. OCR / document translation (via API, with fallback to manual verification)
    5. logging of manager actions
    6. data export (Excel)
    7. security (bcrypt, HTTPS, file access restrictions)

    I work carefully with confidential data, understand NDA requirements, and write clean architecture without "workarounds" and backdoors.
    I also have a production project in my portfolio called SENTINEL — a system with personal dashboards and an admin panel, access roles, statuses and progress of entities, action logging, background tasks (queues), notifications, and data export; in terms of architecture and complexity level, it is comparable to the tasks of your project.

    I am ready to offer:
    1. phased implementation (MVP → expansion),
    2. a transparent work plan,
    3. a demo at each stage.

    I am ready to discuss the details and propose an optimal architecture for your budget and timeline.

    Hello, Mikhail! Seeing your high requirements for the functionality of personal accounts and the admin panel, I would like to offer my services.

    I have significant experience in creating complex web applications with a focus on integration with external APIs and data protection.

    I will pay special attention to the configuration of security and reliability of the backend, including encryption and protection against attacks. Working with Google Drive for storing and processing documents is also within my competencies.

    I am confident that I can make a significant contribution to the implementation of your project and I am happy to discuss the details.

    Hello!
    We offer to create the Razmorozka platform based on NestJS + PostgreSQL + Prisma, using Google Drive, openwebUI AI, and Google Translate for complete automation of document processing. The system will consist of two parts: a secure client portal and a powerful operator administrative block, accessible through the existing "Address" button.

    All client data, statuses, progress, AI results, translations, and logs will be stored in PostgreSQL. Files will be uploaded to temporary storage and then automatically moved to the corresponding Google Drive folder created for each client. After uploading, each document goes through an automated pipeline: AI check → OCR (if necessary) → translation → categorization → status update. If the scanning cannot be processed, the operator receives a notification in Telegram.

    Operators will see all clients with progress indicators, their Google Drive folders, automatically sorted documents, translated versions, and system-generated templates (application, power of attorney, list of participants). They can update statuses, leave comments, request corrections, upload corrected files, and control which sections the client can see. All actions are logged.

    Clients will log in using a password, contract number, or one-time link. Their dashboard will display the necessary sections, upload progress, interface examples, and submitted documents (not subject to editing). Weekly Excel reports will summarize progress with clients for administrators.

    Security includes HTTPS, JWT, RBAC, bcrypt, encrypted fields, file access with URL signing, protection against CSRF/XSS, and a final backdoor audit after project delivery.

    After signing a non-disclosure agreement, we will provide demonstrations of previous personal account systems, document automation interfaces, and administrator dashboards to assist in completing the development.

    AI Consultant with OCR (similar logic): https://217-154-170-186.nip.io/ — here context recognition and real-time data processing have been implemented.

    Lead management system for the US market: n8n + Postgres + CRM. Full automation from receiving emails to creating a structured dossier with logging of every step by the manager.

    Financial dashboards: Development of systems with 2FA, data encryption, and role-based access model (Admin/Manager/Client).

    Technology stack:
    Backend: NestJS (the best choice for scalable logic).

    DB: PostgreSQL (Prisma ORM) for complex relationships between documents and statuses.

    Security: Complete protection against SQL injections, CSRF, and log auditing.

    Infrastructure: Docker, Redis for processing queues of videos/scans.

    I am ready to sign an NDA and conduct a thorough security code review. I have experience writing "clean" code without third-party dependencies that could create backdoors.
