I build analytics systems for teams working across countries, programmes and complex operations.

My work sits between business problems and technical delivery. I design the data pipelines, dashboards, models and AI-assisted tools that make operational work easier to monitor, explain and improve.

I have worked with GardaWorld Security, IOM, CWS RSC Africa and Resolution Insurance Kenya. That experience brings together private-sector discipline, humanitarian accountability, donor reporting and practical automation.

🌍International delivery

Analytics and BI delivery across Africa, the Middle East, UN migration operations, and multi-country security environments.

🤝Cross-cultural collaboration

Worked with governments, donors, UN agencies, NGOs, country analysts, operational leaders, and technical teams.

📈Measurable business value

Focus on time saved, process improvement, risk reduction, data quality, and decision support for leadership teams.

Skills I use to move from raw data to usable decisions.

A practical toolkit across BI, data engineering, machine learning, applied AI, automation and stakeholder leadership.

A cleaner route into the deeper proof.

The main portfolio stays simple. The War Room holds the deeper evidence: impact receipts, audience-specific paths, production readiness, architecture choices and case-study proof rooms.

Ideas behind the work.

Short technical notes and practical reflections on analytics, AI and data products — written for teams that want to move from dashboards to decisions.

Let’s talk about data products that can improve decisions, reporting and accountability.

I am open to senior data, BI, analytics engineering, applied AI, consulting and partnership conversations across Africa, the Middle East and global teams.
