Message

At ArgoBrands, I develop and maintain full-stack applications for warehouse and operational workflows. I built marketplace-integrated order workflows that connect order data to a central stock database, including shipping-label generation, order verification, and inventory management.

I also automated order creation, processing, and reporting with Google Apps Script to reduce repetitive spreadsheet data entry. Earlier, I built an e-commerce capstone with shopping cart and admin features, and developed customer-facing pages and API integrations for an online auto dealership platform.
