About
Developed an interactive web tool that enables consultants and municipal planners to quickly generate, visualize, and compare optimized district-heating network layouts. Built with Next.js, React, and Mapbox, the system integrates AI-driven optimization with intuitive map overlays and a scenario comparison dashboard. It reduced planning time from weeks to just a few hours, improved stakeholder decision-making, and delivered smoother performance o
Challenge, approach, and impact
Handling Large Geospatial Datasets
Challenge: Map performance slowed significantly when loading dense heat-demand and terrain data. Solution: Implemented clustering, tiling, and lazy-loading to ensure smooth navigation and responsiveness.
Balancing Simplicity with Technical Depth
Challenge: Stakeholders needed a tool usable by non-GIS experts, while technical users demanded detailed metrics. Solution: Designed a progressive disclosure interface — showing a simple overview first, with the option to drill down into advanced data.
Aligning Client Expectations with Technical Feasibility
Challenge: Differences between stakeholder design preferences and what was technically feasible. Solution: Held regular review sessions, proposed compromise solutions, and prioritised features that delivered the highest business value.
Ensuring Cross-Browser & Device Performance
Challenge: Users accessed the platform on varied devices and browsers, creating inconsistencies. Solution: Conducted multi-device testing, optimised rendering pipelines, and introduced fallbacks for lower-spec systems.
Driving Adoption Among Non-Technical Users
Challenge: Consultants and planners unfamiliar with GIS tools needed confidence using the platform. Solution: Simplified workflows, added clear visual cues, and conducted usability reviews to refine the interface.
