...finished solution to do: • Track on-hand quantities in real time across all my sales channels. • Trigger a restock the instant preset thresholds are reached, create the purchase order, and route it automatically to my supplier’s API or email. • Update order status and stock counts back to the storefront so customers always see accurate availability. I am open to the tech stack, but the system must be reliable, well-documented, and easy for my team to tweak later (think Python, Node.js, or another mainstream language paired with a lightweight database and clear API integrations). When you respond, please link to past work that shows you have built similar automation or inventory tools. A short note explaining the approach you would take is we...

...lightweight system-monitor overlay that can sit in a corner-or go full screen-through a keyboard shortcut. • Major Improvements to my web browser Axapp. Visual consistency is central. The colour scheme and all icons/graphics must reinforce the deep-space look while staying readable on everyday monitors. Tech notes • Python is mandatory; Python standard library only, no pip installs. • Use the API for app development. • Keep it in TUI, not GUI not CLI. Logistics I can pay 650 ₹ per hour, preferably to an Indian developer for easier timezone coordination. Expect frequent code reviews so we can stay aligned. If you are confident you can merge solid Linux engineering with a convincing space aesthetic, and you fit above criteria, you will be right for t...

I need a single, streamlined tool that can push high-volume messages to both Telegram and WhatsApp through an exposed API. The workflow should be straightforward: I pass a list of chat IDs / phone numbers and message content to your endpoint, the system queues everything sensibly to stay within platform limits, and I get clear delivery reports back. Key points • Platforms: fully support Telegram Bot API and the WhatsApp Cloud / Business API from one codebase. • Core function: send bulk messages (text first; media support is welcome if practical). No separate agent layers or campaign dashboards are necessary. • Optional plus: a lightweight AI-style templating or text-spinning helper for basic personalisation if it adds minimal overhead. • Te...

I run a small business and want to automate how new customer inquiries are handled. Right now I copy details from a Google Form into a spreadsheet by hand and message each customer myself. What I need built: When someone submits my Google Form, the details are added to a Google Sheet automatically. An AI step (OpenAI or Claude API) classifies each inquiry as sales, support, or spam, and writes a one-line summary. Sales inquiries trigger an instant WhatsApp message to me with the customer’s name, request, and summary. The customer gets an automatic confirmation email. A simple weekly summary is sent to me by email. To bid, please include: A similar automation you’ve built, with a link or screenshot Your estimated timeline Any questions about my setup

My production site runs on the React JS on the client, a Node.js/Express API, and MongoDB for persistence. After an external audit with another freelancer I now have a clear list of security weaknesses and several functional bugs that escaped earlier testing. Most of the issues sit in server-side logic: exposed endpoints that bypass auth checks, insecure data validation, and some race-condition edge cases that crash certain requests. On the client, a few components render unpredictable states after failed API calls, so error boundaries and tighter state management will need attention as well. I will share the exact findings (code snippets, Postman collections, and a short Loom walkthrough) at project start. All fixes must be applied directly to the production branch via fo...
