About Me

I am an enthusiast who provides actionable insight into data and perspectives, which helps answer relevant questions relating to any initiatives (rewarded or unrewarded) to gain a competitive advantage and support effective decision-making.

My domain background is IT infrastructure and security, but I have some abilities spanning any full life-cycle quantitative initiatives as showcased by projects in my portfolio. My work is progressively being uploading to GitHub to demonstrate these capabilities, so please check it out.
