Tableau Data Visualisation - Data Structure and Design

@AwaisChaudhry

Hello, I’m Muhammad Awais and I can tighten your Tableau data model by auditing the SQL Server and MySQL joins, mapping them to business rules, and delivering a gap report. I’ll re-engineer data sources and relationships in Tableau (and adjust SQL where needed) to support accurate segmentation logic, then refresh and redesign dashboards for clear cohort breakdowns, faster filtering, and scalable performance. I’ll provide concise hand-over notes and run hands-on training sessions, with step-by-step documentation and recordings for future staff. Milestones will be met with clear deliverables: gap report, re-structured sources, redesigned dashboards, and training materials. I’ll keep you informed throughout and ensure your team can own day-to-day Tableau management after this. What are the top 3 business rules that must drive segmentation? Do you have naming conventions or standards for data sources and fields? What is your target data refresh cadence and expected growth to keep dashboards fast? Are there any privacy or governance constraints I should respect? Do you prefer live training, recorded sessions, or both? What is your target data refresh cadence and expected growth to keep dashboards fast? Best regards,

@MSaadJaved

Hi Anthony, Let's create clear cohort-driven Tableau dashboards by fixing SQL Server and MySQL joins, then redesigning visuals for fast filtering and growth-ready performance. I’ll start by auditing your SQL Server and MySQL joins to pin down the segmentation errors you mentioned and map each relationship to explicit business rules, delivering a gap report that prioritises fixes. I’ve done this for SaaS and healthcare platforms where mis-joined tables distorted cohorts; I rebuilt the data model, corrected join logic in SQL and Tableau, and saw cohort metrics and dashboard accuracy improve. On the dashboard side I redesign for clear cohort breakdowns, fast filtering and tuning for scale, and produce concise hand‑over notes plus recorded hands‑on training so your team owns Tableau day-to-day. I work quickly with strategic clarity and outcome focus; I’m responsive and timezone‑flexible. Happy to chat about next steps. Best regards, Saad

I can help you tighten your data model, rebuild your Tableau dashboards, and leave your team confident to manage everything going forward. I have strong experience auditing complex SQL Server and MySQL sources, correcting join logic, and aligning data relationships to real business rules so segmentation and cohort reporting stays accurate as data grows. I will review your existing workbooks, document current joins, and deliver a clear gap and risk report. I will then re-engineer your Tableau data sources and, where needed, optimise the underlying SQL to support reliable segmentation logic and faster queries. Dashboards will be refreshed with clean, consistent UX, intuitive filtering, and performance tuning so they remain responsive with larger datasets. You will also receive concise handover documentation and live, recorded training sessions that walk your team through data sources, dashboards, refresh processes, and day-to-day management. The result will be accurate reporting, clearer visual stories, and a team that can confidently own the platform.
