What I'm looking for

I’m looking for a role where I can apply my CS background to build and improve products, while handling operational data with accuracy. I want a collaborative Agile environment where I can keep learning and shipping.

I’m a B.S. Computer Science graduate with hands-on experience in the IBM AS/400 (IBM i) environment and a strong drive to build user-focused apps. In my role as AS400 Data Entry at HR Direct Services Inc., I enter and update inventory, shipping, and order data, generate shipping documents and labels, and coordinate with the warehouse team to resolve discrepancies between physical inventory and system records.

Beyond operations, I build software projects that sharpen my engineering instincts: a React Native music app (Expo/create-expo-app), a React journaling web app with light/dark themes and calendar/to-do features, and a Unity 2D platformer with core gameplay mechanics. I collaborate in teams using GitHub and Agile sprints, and I bring clear UI/UX thinking (Figma) plus disciplined development practices like debugging and unit testing.
