    ...times, and the only thing I can see on screen is a “404 Not Found”. Support queues run an hour and, when I finally get through, nothing gets fixed. What I need is straightforward: get my website back online and keep it there. WordPress itself was working perfectly before the migration, so the issue almost certainly lives in the hosting setup—whether that’s DNS, .htaccess, permalink structure, database paths, or something else inside GoDaddy’s environment. Deliverables • Pinpoint the exact cause of the recurring 404 Not Found errors • Apply the necessary fixes so every page resolves correctly • Verify the site remains reachable (no downtime) for at least 48 hours after the repair • Provide a brief summary of what was wron...

    I’m deep into a set of large-scale clinical-trial datasets and need a seasoned partner who can move effortlessly from raw tables to polished Tableau dashboards. The stack is Google Cloud Platform (BigQuery in particular), Amazon Redshift, advanced SQL, and Python, so you should feel at home optimizing long, complex queries, tuning warehouse performance, and scripting repeatable data-quality checks. Where you’ll start I already have a working schema, but it’s straining under growing volume and new KPI requests. You’ll review the existing models, refactor where necessary, and introduce best-practice partitioning and clustering so queries run in seconds, not minutes. From there, we’ll design consumable, high-performance Tableau workbooks that clinicians...

    I run a fast-growing HR-tech SaaS targeting companies (SMBs to mid-market), and I’m looking for an experienced freelance Google Ads specialist to take full ownership of our acquisition on the US market. This is not a generic lead-gen project. The only metric that matters is qualified pipeline — not just form fills. We’re targeting HR manager...only (no agencies or teams) * Looking for someone hands-on, strategic, and comfortable working autonomously Bonus: * Experience in HR tech / ATS / recruiting software * Experience scaling campaigns in competitive US SaaS environments Important: Applications without clear B2B SaaS case studies (including CPL or pipeline impact) will not be considered. If you’re used to thinking in terms of CPL, SQL, and pipeline&mda...

    I already run a custom POS on a PC for my café, backed by a MySQL database. The goal now is to rebuild that experience as a .NET MAUI application that can run cross-platform while sharing the same data source. Core scope • Re-use the existing MySQL schema so staff see the exact products, prices, branches and user accounts they work with today. • Work fully offline when the connection drops, then sync seamlessly once connectivity returns. • Replicate the complete checkout flow from the current system—including order creation, modifiers, discounts and payment confirmation. • Add a “send gift” feature that lets customers transfer prepaid credit or items to another account. • Provide login and sign-up screens, plus a branch se...

    I need a Microsoft Access database built from the ground up to manage multilayer Bills of Materials exported from SolidWorks. The single most critical feature is a master parts table that enforces truly unique part IDs—no duplicates can slip through. Around that core, I also want: • A BOM table that captures all parent-child relationships between assemblies and parts. • An operation table covering every manufacturing step (laser, punch, fold, weld, etc.). • A routing table that ties each part to its sequence of operations. • A revision table so every change is tracked and auditable. The relationships among these tables must be fully defined and referential integrity enforced. On the user side I’m looking for: • A clean part-entry f...

    ...on demand and run seamlessly on more than one EVM chain (at minimum Ethereum, BSC and Polygon). The contract will be called by my website and must expose clear, documented functions so I can expand or upgrade logic later without breaking existing calls. On the front-end I have a “phrase collector” widget where users submit short text snippets. Those phrases need to be written to a lightweight database (your choice of Firebase, Supabase or a comparable serverless store) and the resulting event ID or hash pushed into the contract so everything stays verifiable on-chain. My site already runs on a simple HTML/CSS/JS stack. I need you to wrap it with interchangeable landing-page templates so that I can swap designs by dropping a new template folder in a /themes directory...
