Over deze dienst
Hi, I'm Michael; data analyst and visualization specialist. I design live, interactive visuals and tableau dashboard builds that turn raw data into decisions; whether Tableau for rapid BI or custom React/D3 for pixel-perfect, embeddable web apps. All work is thoughtfully designed, tested, and deployment-ready.
This service offers:
Interactive dashboards: filters, drill-downs, cross-filtering, tooltips.
Data integration: Excel/CSV, SQL/cloud warehouses, APIs; multi-source blending, basic cleaning/modeling.
KPI design: metrics, layouts and narrative aligned to your audience.
Performance: extracts/aggregations, query tuning, pagination, large-data rendering.
Security: env tokens, role-based access (web), guidance for Tableau Public/Server/Cloud.
Deployment & embeds: Vercel/Netlify (web) or Tableau Server/Cloud/Public; seamless site embedding.
Docs & walkthrough: clear handover + 1020 min call/video.
Post-delivery support: fixes within support window.
Premium AI (optional): forecasts, anomaly flags, natural-language summaries.
Platforms: Tableau, React, D3.js (choose one).
Feel free to message me for a tailored scope and quote, looking forward to working on your project!
Michael.

Veelgestelde vragen
Do you provide hosting or deployment for the dashboard?
Yes, deployment is included in every package. I will host the dashboard on platforms like Vercel, Netlify, or your own server. Your app will be configured and launched on your preferred hosting or domain.
How do revisions work if I need changes
Each package includes a set number of revisions. During the revision period, I'll make requested changes (like adjusting charts, layouts, or data handling) until the dashboard meets your needs. Major new features beyond initial scope may have extra cost.
What technology stack will you use? Do you work with WordPress or templates?
It's fully custom: React for UI, D3.js for visualizations, and Node.js/Express (or serverless functions) for the backend. To ensure an optimized, tailored solution, I do not use WordPress, Wix, or templates unless specifically requested for.
Can the dashboard connect to my data source (API, database, etc.)?
Absolutely. I can connect to REST/GraphQL APIs, SQL/NoSQL databases, or CSV/JSON files. Provide the needed access or documentation, and the dashboard will securely fetch and update your data in real time.
Will the dashboard be mobile-friendly and responsive?
Yes. All dashboards are responsive. I use design techniques so charts and layouts adapt to different screen sizes (desktop, tablet, mobile), ensuring your team can view and interact on any device.
What do I need to provide to get started?
You’ll need to provide your data (or existing Tableau dashboards, if preferred) or API/database access, any design preferences or mockups, and deployment details (like hosting credentials or domain). With these, I can begin building and deploying your custom dashboard.
Will I own the code and design after delivery?
Yes. You will own the code and design fully. It’s custom work, so you’ll receive all source code and assets. You can host, modify, or extend the dashboard freely.
Do you provide maintenance or support after delivery?
Yes. I offer ongoing maintenance and support via separate agreements. After delivery, minor fixes are covered under revisions. For longer-term support or new features, we can set up a maintenance plan.
What types of charts and visualizations can you include?
I can create a wide range of visualizations: bar, line, pie, scatter plots, maps, gauges, heatmaps, and more. With D3.js and custom coding, nearly any interactive chart or graph is possible. Just let me know what you need.
