    White-Box Web App Penetration
    6 дні(-в) left
    Верифіковано

    I am ready to put my in-house web application through a thorough white-box penetration test and need a seasoned ethical hacker to run point. Because I can supply source code, architecture docs, and admin-level credentials, you will have full visibility to explore logic flaws, insecure configurations, and anything else that could turn into a real-world exploit. A key requirement is prior experience registering newly discovered vulnerabilities in official government vulnerability databases or repositories; I will rely on you not only to uncover issues but also to craft the correct disclosure package so the finding can be submitted and tracked according to policy.

    Web App Manual QA Testing

    The goal is to complete a thorough round of manual QA on my production-ready web application before the next release. All core journeys—login, form submissions, multi-step user workflows, and the main dashboard—must be verified end-to-end. Testing should run on Google Chrome, Mozilla Firefox, and Safari across Windows and macOS so we can be confident of cross-platform consistency. I also need coverage for every permission level: Admin, Regular user, and Guest. You will exercise standard functional and regression scenarios as well as edge cases to surface UI defects, logic errors, and stability issues. Please explore negative paths in addition to the happy paths, keeping an eye on usability and performance hiccups that might slip past automated checks. Deliverables: • A ...

The task is to take my existing Pro-face HMI application, study how every screen, alarm and data point works, then rebuild the same functionality in the Beckhoff HMI environment so it talks smoothly to a new Beckhoff PLC. You will start by reviewing the current project files I provide, mapping all tags, recipes and alarms. From there, recreate the screens, navigation and any underlying logic in TwinCAT HMI. Along the way I expect you to flag any behaviour that will need re-thinking in Beckhoff, suggest work-arounds, and implement them.

    I run several Pixel 3 handsets on GrapheneOS and need a straightforward way to duplicate my primary phone—complete operating system, settings and chosen apps—onto more devices. I picture a Windows-only desktop application with a clean, friendly GUI that lets me plug a new phone in and replicate the master image with as little fuss as possible. Core flow I have in mind: • Connect master Pixel 3 → press “Create Image” to capture system, data and boot partitions. • Connect target Pixel 3 phones (one after another or several in parallel if you can make that work) → press “Clone” and watch progress bars until each device is ready to boot.

    We ship new features every few days, so quality must keep pace. The task is to own end-to-end testing - both manual and automated; from designing cases right through to signing off each release. Manual coverage is expected on functional flows, user-experience quirks and full regression sweeps.

    My team is ready to streamline several routine processes, and the quickest path is to wire our third-party apps together through Zapier, n8n, or —whichever tool best fits each scenario. The objective is simple: build reliable connections that automate complete workflows from trigger to final action. Expect to start with a brief discovery call so I can outline the exact apps in play and the business rules that drive each flow. Once the map is clear, I’ll count on you to: • Configure and test every connection until data moves hands-free and error-free • Optimise the logic so each step fires only when it should, avoiding duplicate tasks or loops • Document the finished automations in a concise hand-over note I can follow later You’ll have direct acces...

All products and their sub-categories must live in the database and be created or modified through a dedicated admin dashboard—no code edits or CSV uploads, just real-time forms that write directly to PostgreSQL. Core user-side features come first: powerful product search with layered filters (category, price, trending, etc.), a secure payment gateway integrated end-to-end, and authentic customer reviews with star ratings.
