Personal bio

I am a seasoned Commercial & Contractual Affairs Leader with 20+ years of cross-continental experience delivering high-value CAPEX projects in infrastructure, industrial, maritime, commercial, and diplomatic sectors across Africa, the Middle East, and Europe.

Specialised in FIDIC-based contract administration, cost engineering, and claims/dispute resolution for EPC/Turnkey and public procurement frameworks, I have advised government entities, global contractors, and leading engineering consultancies on projects exceeding USD 400 million.

From business setup and tendering to post-contract execution, delay analysis (SCL 2017), claims negotiation, and final account settlement, I bring a strategic, results-focused approach that safeguards commercial interests and optimises project outcomes.

Fluent in both Anglophone and Francophone legal and business environments, I excel at leading multicultural teams under high-pressure conditions, ensuring contractual compliance, financial security, and operational excellence.

I bring strategic clarity, contractual discipline, and cost efficiency to EPC and public infrastructure programs worldwide—poised to deliver value in client advisory, claims management, and cross-border dispute resolution
