Selected Work
Chewy Prescription Management Platform
Technicians and pharmacists needed a more efficient and accurate way to review prescriptions and perform drug utilization review while minimizing cancellations on autoship orders.
Controlled Substances Compliance & PDMP Integration
Handling controlled substances required strict compliance with state-level PDMP checks and regulatory requirements, but existing systems were not designed for these workflows.
Internal AI Knowledge Assistant (Org-wide Chatbot Platform)
Engineers and teams needed faster access to internal documentation, workflows, and systems without manually digging through multiple tools and repos.
Fax OCR & Textract Prescription Workflow
Fax prescription forms were difficult to read and process, resulting in poor readability and manual effort for pharmacy staff.
