I have a live WordPress project that needs several critical fixes and add-ons, all to be managed in a single GitLab repository. The very first milestone is to eliminate the Google sign-in failure that appears only in webview mode; once authentication works flawlessly, we can move on to the rest of the build. After that I need three things wrapped up: • Store-card API integration – the site must be able to accept and validate gift, loyalty, or similar cards through the existing back-end endpoint. • Payment gateway connections – Stripe, PayPal or another well-documented option can be wired in as long as it supports one-time and recurring charges. • Final wiring so every new component sits cleanly inside the current WordPress theme and plugin stack. All code must be committed to the GitLab repo with clear, meaningful commit messages. I’ve set aside a total budget of US $500, so please keep that figure in mind when you size the effort; I’m happy to break it into milestones with a fair split once we agree on the sequence. Acceptance will be based on these checks: 1. Google OAuth in webview signs in on the first attempt, returns correct scopes, and survives a full log-out / log-in cycle. 2. Store-card calls return valid JSON and update the user account without error. 3. Payments process in test and live mode, with webhook confirmations updating WordPress order status. 4. No PHP warnings, console errors, or unresolved merge requests in the final GitLab branch. If this fits your skill set and you’re comfortable delivering the above within the stated budget, let’s get started.
