Built a fully interactive executive project dashboard in Microsoft Excel for tracking enterprise implementation projects. This solution combines project timelines, milestone tracking, budget monitoring, task status, project priorities, and pending decisions into a single executive view. Designed to improve stakeholder visibility, streamline project reporting, and provide real-time insights for project managers and leadership teams.
I created this sales dashboard in Microsoft Excel to analyze sales performance and present business insights in a clear, visual format. The dashboard includes KPIs, monthly sales trends, product-wise analysis, order status distribution, a sales histogram, and outlier analysis using a box plot. I used Pivot Tables, Pivot Charts, Excel formulas, and data visualization techniques to transform raw data into meaningful insights that support data-driven decision-making.
Mandum Rimba Project.
Mandum Rimba is an open-source geospatial platform, I designed and developed to make environmental and conservation data more accessible, interactive, and easier to understand.
The platform brings together dozens of spatial datasets, including protected areas, endangered wildlife, deforestation, peatlands, mangroves, concessions, wildfire hotspots, and biodiversity records, into a single WebGIS experience.
Beyond visualization, I built features that help users explore complex environmental issues through interactive maps, story-driven content, spatial analysis, and automatically generated reports.
The project was built from the ground up using a modern full-stack architecture, with a strong focus on performance, usability, and scalability.
What I worked on
- Full-stack architecture and development
- Interactive WebGIS and map visualization
- Spatial data processing and optimization
- Backend API and database design
- UI/UX design
- Data integration from multiple environmental sources
- Performance optimization for large geospatial datasets
Tech Stack:
