At Chewy, I built responsive React and Next.js front ends over Node.js and Python services for customer-facing and internal workflows. I also integrated REST APIs, webhooks, and MCP fulfilment servers across services.

I shipped production AI features, including RAG-grounded natural-language querying and token-streamed responses. PostgreSQL schemas with row-level security and audit-oriented design helped keep multi-user data consistent and access scoped by role.

At Nature's Path Foods, I built a configurable Price Management SaaS that gave sales teams fast, accurate quotes in place of manual spreadsheets. I also integrated a merchant CRM with finance and supply-chain systems to sync contacts and transactions and automate month-end reconciliation.

At Drawboard, I delivered and supported a cross-platform client application for 10k+ users, with a focus on dependable offline-capable field use. I worked on reliability, monitoring, and safe change delivery.
