    I have full access to a PHP code-base that I can share immediately. I already know exactly which file and function contain a hidden back door; I just need a seasoned developer to: • remove every trace of that back door cleanly, • rebuild/package the application so it runs flawlessly after the fix, and • verify the change with a quick security review and functional smoke test. You’ll receive the source archive, a short note pointing to the suspect section, and the steps I normally use to deploy. Hand back the cleaned code, a brief changelog, and confirmation that the application still behaves as expected on a standard LAMP stack.

    I am ready to invest time in mastering n8n so I can design and run my own no-code, AI-assisted automations. I already have a few simple flows in mind but need structured guidance to go from basic triggers to production-ready workflows. Here’s what I expect from our collaboration: • Short, live coaching sessions (screen-share preferred) where you walk me through real examples and answer questions on the spot. • Clear explanations of core n8n concepts—triggers, nodes, error handling, environment variables, credentials—so I understand not only how but why each piece works. • Practical tips on scaling, securing, and monitoring flows once they are deployed. • A concise set of reference notes or recordings after each session so I can review...

    I need a full-feature, web-based no-code app builder that mirrors the user experience and power of Base44. The platform has to let non-technical users create production-ready apps through a clean drag-and-drop interface, start quickly with polished pre-built templates, and fine-tune every screen via fully customizable components. Generated apps must compile for iOS, Android, and Web from the same project, with an automated build pipeline that produces store-ready IPA, APK, and a responsive web bundle. Core integrations are essential: • Payment gateways (e.g. Stripe, PayPal) ready to switch on from the editor • Universal third-party API connectors that users can map to data sources without writing code • Social media login using standard OAuth flows for ...
