    I need an experienced Notion builder to create a streamlined personal-organization hub focused on two things: keeping my tasks under control and tracking the goals that matter most to me. The core database should open in List view—this is how I naturally process information—yet still be structured well enough that I can later switch to Kanban or Calendar if I ever change my mind. Here’s what the workspace must cover: • A task-tracking system with statuses, priorities, due dates, and a clean List view as the default. • A goal-setting area that links seamlessly to the tasks so every action clearly rolls up to a bigger objective. Once the build is complete, I’ll also need a quick loom or written walkthrough so I can tweak properties and filters on my ...

    My current data platform is overdue for a full-scale health check and future-proofing plan. The workload is hybrid—heavy transactional traffic combined with analytics—and I need clear, vendor-neutral guidance on whether the existing setup should stay on-prem, shift to SQL, NoSQL, or even a NewSQL engine, and which cloud provider (AWS, Azure, or Google Cloud, or another) would suit the roadmap best. What I expect from you: • A concise audit of the present environment covering performance, security, scalability, backup/DR, and cost drivers. • Best-practice do’s and don’ts tailored to a hybrid workload. • A migration and integration blueprint that shows how the database layer should connect with the application, analytics, and orchestration layer...

    I have bike-sales data sitting in a SQL Server database and I need a clear, insight-driven view of what is really happening in the business. You will start by writing well-structured SQL—JOINs, GROUP BYs, subqueries, the works—to pull everything together. From that result set, build an interactive Power BI dashboard that surfaces the three core KPIs I rely on: Revenue, Sales Volume, and Profit Margin. Because our immediate focus is growth in Asia, the visual story must spotlight that region’s performance while still letting me drill into individual models to see which bikes are driving results. The finished dashboard should help my team make faster inventory and demand-forecasting decisions, so usability and speed matter as much as visual polish. Deliverables I expe...

    I have a live database that holds several hundred records which now need to be migrated, field-by-field, into a new database. Everything is already structured; the task is strictly copy-pasting each value into its matching field while keeping the original order intact.

I will provide: • read-only access to the source database • write access to the destination database plus a short video walkthrough of the required workflow What I expect back: • every record copied over without omissions • consistent formatting of dates, numb...
