    I’m launching a medium-scale online store that serves customers exclusively within my city. The site will sell physical goods only, so the buying journey must feel fast and friction-free from browsing to doorstep delivery. Core functionality I need you to put in place for this MVP: secure user registration/login, full product catalogue and cart flow, a checkout that accepts credit/debit cards, popular digital wallets, UPI, and a fallback Cash-on-Delivery option, plus separate dashboards for Administrators, Vendors, and Customers. I’m flexible on the tech stack—Laravel, Django, or a modern JavaScript framework such as React with Node/Mongo are all fine so long as the code is clean, well-documented, and scalable for future city-wide growth (think flash-sale traffic sp...

On the frontend you’ll ship responsive React interfaces that consume those services smoothly. Our data layer runs on MongoDB, so you’ll model documents, tune queries, and manage indexing for performance and scale. Day to day you’ll touch every layer of the stack—from server-side architecture and deployment scripts to pixel-perfect components—so broad curiosity and independent problem-solving are essential.

The URI is tucked away in an environment variable, but at runtime I receive a generic “connection string” error and no data appears. I need someone to: • review how I’m importing the .env values and verify the string syntax • confirm the driver / library I’m using from the React side (or its Node-based API layer) is configured correctly for an Atlas URI • diagnose any authentication, whitelisting, or network nuances that Compass might mask • deliver a working example and a brief explanation so I can replicate the fix across environments Once the project builds and fetches data from Atlas without throwi...

    I am building Meet-sphere, a browser-based video calling platform geared toward friends and family.

I now want to move from demo to production quality by adding: • Screen sharing that works smoothly on Chrome, Firefox, and Safari • Multi-user conferences (3–6 participants in a room without noticeable lag) • An integrated text chat pane, delivered over the existing socket layer and persisted to MongoDB for reloads The codebase is modern React (hooks, Context, Vite), and the server runs on Express with JWT auth.

Only portions of the existing schemas are documented, so the very first step will be to inspect each system, reverse-engineer any missing metadata and confirm table relationships.

    My container is deployed on Cloud Run and attached to a VPC via a Serverless VPC Access connector that in turn goes through Cloud NAT with a public IP. A custom domain is mapped as well.

I have already reviewed firewall rules, confirmed the NAT configuration, and inspected container logs, yet outbound traffic still fails (other external endpoints time-out too).
