In my opinion, I think this setup is most suitable to do in web. You need many features, for instance role based features, which are easy to create in web. Additionaly, you need to do crud operations, which are again easier with several feature types. We can create role-based web App with admin having all access, and other users have restricted access like you have mentioned. We can then implement the dashboard having drilling features like you have mentioned. That is show the information at abstract level, and then the detailed views in categories. The important thing here is that whether the new data will be imported into the system regularly? Or you will have a 270K record base, and onwards web app will be used to add records? I have created dashboards in the past, and I can share relevant examples with you. I will be happy if we can discuss this further. Regards.

Hi, I can build this urgently as a secure web-based dashboard using a cloud database (instead of Excel/Google Sheets alone) for better performance with 270K+ records, with role-based login for Admin and DUN users, fast filtering, Excel import/merge, and a clean professional dashboard UI. My recommended stack is Laravel or Node.js backend + MySQL/PostgreSQL + responsive admin dashboard, because it will be more scalable and maintainable than relying only on Power BI for heavy data management and role restrictions. I have experience with large-data dashboards and can deliver a practical first working version quickly, with timeline depending on final scope but I can prioritize a 24–72 hour MVP for core dashboards, login, filtering, and data import.

Hi, I see you need a scalable, role-based online dashboard for “Bantuan Kasih Johor” to manage and visualize 270K+ records from Excel, with both Admin and DUN user access. The goal is to provide a fast, user-friendly dashboard that allows admins to manage data, and DUN users to view filtered records, with interactive analytics by aid category and region. I would build this as a web-based dashboard using a cloud database (MySQL/PostgreSQL) to handle large datasets efficiently, with a responsive frontend for clean, modern UI/UX. Admins can add/edit/delete records, upload and merge new Excel files, and changes will reflect in real-time. DUN users will see only their assigned data. The dashboard will include interactive charts and drill-downs for aid categories and DUNs. I’ve developed large-scale dashboards with role-based access and real-time updates, ensuring fast load times even with hundreds of thousands of rows. Suggested timeline: 48–72 hours for full delivery with testing. Preferred tech stack: Web App (React + Node.js) + Cloud DB, optionally Power BI if rapid deployment is needed. Happy to discuss the architecture and start immediately. https://www.freelancer.com/u/mhmamun360 Best regards, Injaazh.

Hi — I can build a fast, scalable dashboard for your Bantuan Kasih Johor dataset with proper governance and role-based access. Given the size (270K+ records and growing), I would not rely on Excel/Google Sheets as the primary engine. My recommended setup is: • Backend: Cloud database (PostgreSQL / BigQuery) for speed and scalability • Frontend: Power BI Service (with Row-Level Security) or a lightweight web app (React + API) depending on your preference • Integration: Admin upload tool to merge new Excel files directly into the database with validation This ensures fast filtering, real-time updates, and long-term reliability. I’ve worked on finance and operational dashboards where large datasets required clean structuring, optimized queries, and intuitive drill-downs. Here’s how I’d approach yours: • Build a structured data model (optimized for filtering by DUN & Jenis Bantuan) • Implement secure login with role-based access (Admin vs DUN users) • Design clean dashboards with clear KPIs and click-through views to full recipient lists • Ensure fast load times using indexed queries and optimized measures • Mobile-friendly, minimal, and easy to navigate Admin will be able to add/edit/delete records and upload new files, with updates reflected instantly. Happy to quickly review your dataset and suggest the best architecture before starting. Regards, Taha

The real issue here isn't Power BI vs web app. Still, it's storing 270K+ rows correctly so filtering stays fast and admin imports don't break the dataset. And i would build this as a lightweight web app with database-backed storage, role-based login, Excel import/merge, and separate Admin/DUN dashboards. that's safer and more scalable than keeping Google Sheets as the main source. I'm Artur, full stack developer since 2011. I can offer a very competitive price to help me grow on this platform with a good review. while still delivering clean and fast work.
