The workflow is straightforward—once authenticated with my account, the script should pull a link from a list (CSV or JSON, whichever is easier), dispatch it through the platform’s approved method for messages or posts, then log success or failure before moving on to the next item. I’m open to whatever stack you feel is most reliable—Python with the platform’s official API, Node.js using puppeteer, or another language if rate limits and security are handled cleanly—but I do want clean, well-commented code and a quick read-me so I can spin the bot up on my own machine. Deliverables • Complete source code ...

Cloud360 is moving into Phase 2, a cycle dedicated solely to squashing the bugs that surfaced after launch. I’ll hand you a clearly documented backlog—steps to reproduce, log excerpts, and a link to the Git repository—and expect clean, well-commented patches submitted via pull request. Each fix must be accompanied by unit tests and must pass the existing CI pipeline before we promote it to our staging environment. The stack is a typical cloud-native mix of Node.js, React, PostgreSQL, Docker, and AWS services, with automated testing through Jest/Mocha and a CI/CD workflow.

I’m refreshing an existing production app built with on the front end and Express plus a few Python micro-services on the back. The whole stack runs in Docker containers orchestrated by Kubernetes. The task is a comprehensive update—user interface, backend logic, and database layer all need attention—but we are not adding new features.

I need our Firebase project to start sending email notifications through the official “Trigger Emails” extension. All message bodies are already stored as plain-text documents in a Firestore collection, and I only want an email dispatched when an Order confirmation event occurs. Here’s what has to happen: • Install and configure the Trigger Emails extension in our existing Firebase project. • Map the correct Firestore collection path so the extension pulls the plain-text template for each order. • Wire the extension to fire exclusively on the order-confirmation event (a new document insert in /orders, or similar—happy to clarify). • Prove it works by triggering a test order: I expect the message to reach my inbox with the exact text stored...
I need an end-to-end solution that lets our users open a React-based dashboard each morning and instantly see fresh, role-specific metrics. Here is the flow I have in mind: every night a batch job connects to our SQL databases and a couple of internal APIs, pulls the required product data, and writes a clean, report-ready snapshot into a staging table (or tables) that you design. As soon as a user loads the dashboard, individual widgets fire the SQL you attach to them, read from that snapshot, then hand the results to a rendering layer that turns the numbers into the appropriate visual—bar graph, doughnut, pie chart, line graph, or whatever makes the most sense for that data point. Each widget also checks the visitor’s role and shows or hides itself accordingly, so our sa...

I’m building a full-stack web platform that sells access to an in-house large-language-model (LLM). The site’s core is e-commerce, but instead of one-off product sales I need subscription services with clear, tiered plans (think “Starter”, “Pro”, “Enterprise”).

I’m ready to retire the old PHP backend that powers my website and rebuild it in Node.js so the platform can scale without strain. Today the app runs on MySQL, authenticates users, performs a mix of simple and complex database queries, and talks to several external services through REST APIs. I need every one of those capabilities transferred to the new stack with behaviour, data, and response formats unchanged. You will have full access to the existing PHP codebase, database schema, and the live API keys. Using Node.js—Express, Koa, or a framework you’re comfortable with—your task is to mirror the current functionality and leave room for future horizontal scaling. Deliverables • User authentication flow reproduced in Node.js, maintaining current password-h...
