Climate Risk Scoring Dashboard — Malawian Districts Python · Streamlit · Plotly · IPCC AR5 National risk assessment platform across all 28 districts. 50,000+ daily records (2020–2024). SPI + Coefficient of Variation with percentile normalization. Choropleth maps and radar charts — policymakers identify high-risk districts in under 5 seconds on mobile.

WasteWatch — Waste Management DSS Python · FastAPI · Next.js · DBSCAN Geospatial decision-support system for Blantyre City Council. 333+ illegal dumpsites mapped. Custom 0–100 risk scoring engine across health, environmental, and volume factors. DBSCAN for skip placement optimization. Deployed to production.

Malawi Climate Data Pipeline & Dashboard Python · PostgreSQL · Streamlit · NASA POWER API Automated ETL pipeline centralizing 10,950+ daily climate records. Interactive dashboard for Blantyre, Lilongwe, and Mzuzu — eliminates manual CSV handling across the full workflow.

Ascend Spatial Labs Platform Next.js · Mapbox · Clerk · Sanity Full company site and client portal for a geospatial intelligence startup. Clerk auth synced to Sanity, project visibility states, webhook retry logic, transactional email. Live.

Evaluation of Climate Finance in Malawi — BSc Thesis Python · Excel · QGIS · MAXQDA MWK 16B+ analyzed across 48 CCA projects (2018–2023). Found 85% international grant dependency, 65% forestry concentration, 11 underserved districts. Presented to department committee.
