About

Engineering, ESG and climate resilience — practiced where it matters most.

I'm an International Development Specialist working at the intersection of environmental safeguards, water and sanitation, and sustainable infrastructure. My work supports donors, governments and contractors to deliver compliant, durable projects in some of the most fragile and climate-vulnerable parts of Kenya and the Horn of Africa.
