Climate Data Scientist · Geospatial Engineer · Founding CTO, Ascend Spatial Labs
BSc Meteorology & Climate Science (MUST, 2025). Graduate Intern at DCCMS — Engineering & Communication division — working on meteorological infrastructure, data pipelines, and decision-support systems. I build tools that go from raw climate or sensor data to deployed products that inform real decisions.

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.
