About Me

I am an adaptable, resourceful, technology-driven professional. Along the way I developed a strong interest in technology and gained exposure to data analytics, SQL, data modelling, system analysis, software testing, application support and technical support.

I have worked alongside Business Analyst and DevOps teams on business applications built from defined requirements. My business administration and operations background helps me connect what the business needs with the technical solution that supports it.
