Head of Engineering | Software Development • Data Engineering • Data Analytics

Experienced technology leader managing large-scale data operations and engineering teams in the financial services sector. I bridge the gap between technical execution and business outcomes, having led initiatives that process 566+ million records and 1.4TB+ of data monthly.

I lead engineering teams in building robust, scalable systems that handle mission-critical data operations in highly regulated environments. My focus is on delivering reliable solutions that meet strict compliance requirements while maintaining high performance standards.
