I need a program or Telegram bot for bulk creation of shipping documents through the Nova Poshta API.Main Task I upload 50–100 orders at a time into an Excel/Google Sheets/CSV table or paste a list of orders into the program. Clients provide data in different formats, so the system must automatically recognize the data, sort it into the necessary fields, and create shipping documents through the Nova Poshta API.Input Requirements Possible options: Upload an Excel/CSV file. Copy a list of orders into the program. Paste client messages in free format.What the Program Must Recognize From each order, it is necessary to determine: Recipient's full name; Phone number; City; Nova Poshta branch; Product/comment; Cash on delivery amount; Weight/dimensions, if specified.Operational Logic I upload 50–100 orders. The program processes each order. Data is automatically distributed into columns. The program checks the city and branch through the Nova Poshta API. If there is an error or missing data for an order, it highlights that order and indicates what needs to be corrected. If everything is correct, it creates the shipping document. After creation, it shows a list of completed shipping documents. It allows exporting the result to Excel.Output After Processing For each order, it is necessary to obtain: Shipping document number; Client's full name; Phone; City; Branch; Cash on delivery amount; Delivery cost; Status: created / error / needs verification.Mandatory Functions Bulk creation of 50–100 shipping documents at once; Verification of city and Nova Poshta branch; Ability to edit an order before creating the shipping document; Saving sender data; Working with cash on delivery; Exporting created shipping documents to Excel; Log of created shipments.Desirable Telegram bot or simple program for Windows; Excel/CSV upload; Ability to paste a list of orders as text; Saving a database of regular clients; Reordering with one click; Product and weight templates; Printing/downloading labels for packages.Important I need not just a form for manual filling, but a tool for bulk processing of orders. Main scenario: I upload 50–100 data entries, the program sorts the information itself, checks for errors, and bulk generates shipping documents through the Nova Poshta API.

Project: YOKA ASSIST — intelligent diagnostic and training system for mining equipment Project Description It is required to develop the YOKA ASSIST intelligent system based on a Telegram bot using artificial intelligence. The main task of the project is to create a digital assistant for electricians, mechanics, operators, and engineering and technical personnel, which will assist in diagnosing faults, training employees, and storing a technical knowledge base. The first stage of the project is focused on mining equipment (EKG excavators, SBSh drilling rigs, and other equipment), but the architecture should be universal and easily scalable. Main Functionality Telegram Bot - Modern interface. - Menu with buttons. - User authorization. - Access rights separation (user, administrator, chief administrator). Artificial Intelligence Knowledge Base A knowledge storage system needs to be created. Support: - PDF; - Word; - Excel; - photographs; - diagrams; - videos; - instructions; - equipment passports; - technical documents. After information is added by the administrator, the AI should use it in responses without changing the program code. Equipment Diagnostics Search support: - by error code; - by protection name; - by cabinet; - by unit; - by equipment; - by symptoms. For each fault, it is desirable to provide: - description; - possible causes; - sequence of checks; - photographs; - diagrams; - video materials; - links to related documents. Dynamic Buttons Buttons should be generated automatically depending on the situation. For example: - Check cabinet. - View diagram. - View video. - Next stage of diagnostics. - Go back. Administrative Panel The chief administrator should be able to: - add equipment; - create new errors; - add documents; - upload photographs; - upload videos; - edit the knowledge base; - manage users; - assign administrators of individual departments. QR System Each cabinet, unit, or equipment can have its own QR code. After scanning, the user immediately enters the corresponding section of the Telegram bot. Repair Log A log of completed work needs to be implemented. Functions: - who performed the repair; - date and time; - equipment; - description of completed work; - materials used; - comments; - repair history. Analytics It is desirable to implement: - most common faults; - repair statistics; - time to resolve faults; - reports on equipment; - reports on employees.

I'm looking for an experienced Python developer who can conduct a full audit of the existing project, fix errors, and bring it to fully stable operation. If necessary, a complete redesign of the project architecture or writing a new implementation while preserving all necessary functionality is allowed. What I will provide The source code of the current bot. A video demonstrating how the bot should work. A complete technical specification with the logic of operation. Main task The goal is to restore the stable operation of the bot and ensure the execution of the full scenario without failures. If the current architecture cannot be effectively fixed, a complete redesign of the project is allowed. The main objective is not to preserve the existing code but to obtain a fully functional, stable, and maintainable product. What needs to be done 1. Conduct a project audit Before starting work, it is necessary to: study the existing code; identify the reasons why the bot stopped working; assess what can be fixed and what is more reasonable to rewrite. 2. Restore all functionality After the work is completed, the bot should correctly execute the entire scenario: registration of a new account; confirmation of login via code from email; authorization; execution of the scenario according to the technical specification; completion of work; transition to the next account. All stages must work automatically without manual intervention. 3. Fix existing errors It is necessary to eliminate any errors related to: authorization; receiving the confirmation code; unstable operation; freezing; unexpected program termination; errors after website updates; incorrect exception handling. 4. Make the project resilient The bot must: correctly handle errors; not enter infinite loops; automatically terminate unsuccessful scenarios; correctly continue operation after non-critical errors; maintain clear logs. 5. Control panel It is necessary to preserve or redesign the control panel. It should allow: to start and stop operation; to change necessary settings; to view the current status; to view the log of operations and errors. The interface should be clear and stable. 6. Code Code requirements: clear project structure; separation of logic into modules; possibility of further support. 7. Compatibility The project must run on a modern version of Python. The contractor must provide a complete list of dependencies and instructions for running. 8. Result verification Before handing over the project, the contractor must demonstrate a fully working scenario on video: project launch; completion of the full cycle; absence of errors; correct operation of all functions. What to provide after completion source code; all modified files; instructions for running; list of dependencies; video demonstration of operation; brief description of the changes made. Important The work is considered completed only after all functionality described in the technical specification and demonstration video works stably without critical errors. If during the audit it turns out that the current project cannot be effectively fixed, a complete redesign is allowed while preserving all necessary functionality. When responding, please indicate immediately: experience with Python; experience in browser automation (Playwright, Selenium, or similar tools); experience with REST API; cost of work; estimated completion time.
