Telegram bots to form a client base with olx website processing

Technical task for a Telegram bot / mini-platform 1. Project goal Create a Telegram bot and mini-platform for finding specialists and posting requests from users. The user can leave a request, the specialist can respond, the administrator controls publications, moderation, payment, and security. 2. User roles User: can register; confirm phone number and email; create a request; view specialists; receive responses. Specialist: can register; fill out a questionnaire; specify services, prices, city, experience; add photos of completed work; respond to requests. Administrator: can moderate requests; verify specialists; review complaints; manage advertising; control payments; block users. 3. Registration Mandatory: confirmation of phone number via Telegram or code; confirmation of email via link or code; without confirmation of phone and email, the request is not published. 4. Requests The user fills out: service category; task description; city/region; deadline; budget; photo (if necessary); contact details. Limitations: no more than three requests per day from one user. 5. Moderation All requests initially go for moderation. Automatically block or send for manual review: photos of category 18+; spam; offensive statements; suspicious links; duplicate requests; mass requests from one account. 6. Specialists Specialist questionnaire: name; city; services; experience; prices; portfolio; photo; description; link; reviews; verification status. Important: the platform is not responsible for the quality of the specialist's services. This must be stated in the user agreement. 7. Payment Monetization options: paid placement of the specialist's profile; paid boosting of the profile; paid access to requests; advertising after approval by the administrator; subscription for specialists. Integrate payment: Stripe / Przelewy24 / PayU / Fondy — as per the developer's capabilities. 8. Administrative panel It is necessary to create a convenient admin panel: list of users; list of specialists; requests under moderation; complaints; payments; statistics; blocking users; editing categories; managing advertising; manual approval or rejection of publications. 9. Security Mandatory: protection against spam; request limit; message limit; protection against mass registrations; action logging; database backup; file and photo verification; CAPTCHA or other spam protection mechanism; blocking by phone number, IP address, or Telegram ID. 10. Responsibility The user agreement must specify: the platform is not an employer; the platform is not responsible for the actions of specialists; the user independently makes decisions about cooperation; the administration has the right to delete a request or profile without explanation; advertising is published only after approval by the administrator; spam, fraud, 18+ content, and any manifestations of aggression are prohibited.

Good afternoon. I need a keyword parser that outputs results through a Telegram bot. How it should work: Automatic search on 4 websites for keywords that change from time to time. Search queries are sent every few minutes. The words are uploaded in the form of a .txt file. The Telegram bot should have buttons: start bot, stop bot, download file (downloads a file with active keywords), upload file (uploads an edited file with new words). The bot should ignore previously found results, i.e., it should not indicate the same ad twice. The result comes to the bot in the form of a link with a photo, but just a link is sufficient. P.S. searching websites without API, VPS with 6TB and 50 IPs are already available. For detailed information, please contact me via private message.

Development of a Telegram Mini App (store) with CRM and Nova Poshta integration It is necessary to develop a Telegram Mini App (store inside Telegram).Main functionality A catalog with approximately 20 products is needed. For each product: photo; name; description; price; model selection; color selection; quantity. Order processing The client must have the ability to: view the catalog; add products to the cart; change the quantity; place an order; enter: name; phone; city; Nova Poshta branch number; payment method; order comment. CRM All orders need to be automatically transmitted to the CRM via API. It is preferable that the integration is universal and in the future, the CRM can be changed without a complete redesign of the project.Nova Poshta Integration with the Nova Poshta API is needed or data transfer to the CRM if the creation of the shipping document will be done by the CRM itself.Administrator A simple administrator mode is needed: adding and editing products; changing prices; changing stock levels; adding new colors or models. Important The project must work as a Telegram Mini App (not a regular bot with buttons). The code, database, and all access after the completion of work must belong to me. The architecture must allow for additional features to be connected in the future without a complete redesign. Please inform: Estimated cost. Completion time. What technology stack you plan to use. Do you have experience in developing Telegram Mini Apps and integrating with CRM and Nova Poshta API.

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.
