Our old custom system has outlived its usefulness, we need to grow. We are looking for an experienced professional to implement ERPNext. Must have experience, our field is wholesale and retail trade. There will be a lot of different standard and non-standard solutions, as well as classic connections to PRRO, Bank Mono and Privat, Nova Poshta, marketplaces, and so on. Ready?! :) Then send your resume and let's get to know each other.

General information: There is a Telegram bot written in Python (aiogram v3, aiohttp, MySQL, Redis). This is a service for interaction between clients and performers (profiles, projects, etc.). Required skills: - Confident experience with aiogram v3 (not v2!), asyncio, aiohttp; - Knowledge of Telegram Bot API (webhooks); - Experience with MySQL, Redis; - Ability to understand someone else's code; - Communication skills, responsibility. I need to fix a bug in the current version of the bot directly on the server. The problem is as follows: The chats (Nooks) are not functioning properly; there should be a cleaner that works according to an algorithm, but right now it is working with bugs and not cleaning on schedule. - A chat between the client is needed for discussing work matters with the performer. - Chats (nooks are already created, they need to be cleaned and queued. - The user bot creates chats (pair nooks, which we already have) and puts them in the queue; if a deal is made in the chat, the interlocutors are present (one chat for the performer, another chat for the client); if the chat is closed or there was no deal made and users did not write there for 7 days, the bot removes clients or performers from there and puts this chat (nook) back in the queue. - The client can switch to a chat with any performer who responded to the order. - The client and performer are in two parallel chats, so there is no possibility to see the direct account of the interlocutor and no possibility to write to them directly. * We do not change the operation of the chats and everything else. The main thing is that the fix does not lead to other problems.

Auto-notification system for inventory replenishment analytics. On 8n8. Small automation for e-commerce. Once a day, the system calculates the sales velocity for each product and sends a message in Telegram indicating when to reorder (with the recommended quantity) and how many days the remaining stock will last. What we do: Data retrieval: KeyCRM API (order history) + stock/orders from Rozetka (API or export) Storage in SQLite on my VPS (Contabo, Linux) Calculation of average sales, days of stock, reorder point ABC analysis: prioritization of which product to replenish first (class A — main by revenue — more important) Daily Telegram bot + cron job All thresholds (lead time, safety stock, target stock) — in the config

Hello! I need to visually customize the InvenTree system (open-source) for a coffee shop project presentation. A complex backend and integration with the cash register (POS) are not required — the external redesign of the interface is important to show the difference between "Before / After". Project stack: Python (Django) + React (Mantine UI). What needs to be done in the interface: Custom branding, Renaming in the sidebar menu and tables, Cleaning forms from engineering fields, Setting up one recipe for "making" a drink (for example, Cappuccino), so that when manually deducted from the warehouse, all ingredients are visually subtracted, adding functions in the form of additional reports, and explaining the principles of the changes made. We will discuss all specific details in person. Requirements for the performer: Experience with Django and React (Mantine UI). Ability to complete the task quickly — the project is needed for a presentation. We work through Safe (Secure transaction). In your response, start with the word "COFFEE", so I know you read to the end. Please provide your timelines and price.

A small adjustment is needed in the program that generates print orders. Task: We have added to the assortment soft glass with print. In the orders, the name of the print will be highlighted with the symbols #...# for correct recognition. Example: Soft glass, #White abstraction# 2.0mm, Shape: Rectangle... Requirements: If the text of the order contains a fragment between the symbols #...#, the program should recognize it as an order with print; when generating a PDF or print sheet, such an order needs to be highlighted in a different color (any noticeable color, to be agreed upon during execution); the rest of the program's logic should remain unchanged. An example of the order is attached below for testing.
