About

I build products end to end.

I'm a full-stack software engineer focused on building reliable, intuitive web applications and AI-powered product experiences. I work across responsive interfaces, backend APIs, databases, authentication, payments, cloud services, and production delivery.

Most recently, I helped build Quill & Pigeon's multi-tenant commerce platform and developed AI-assisted product experiences using the OpenAI API, Claude API, MCP, Langfuse, and workflow automation tools.

Quill & Pigeon

Full-Stack Software Engineer Co-op · Portland, Maine

Built customer-facing product features, commerce workflows, AI-powered experiences, and production infrastructure for a multi-tenant platform connecting customers with independent greeting-card artists.

Full-stack product development

Built accessible customer experiences for product discovery, personalization, recipients, reminders, subscriptions, checkout, and card delivery using Next.js, React, TypeScript, Prisma, Zod, and PostgreSQL.

Commerce, subscriptions, and card credits

Extended Medusa with custom subscription-credit and payment-provider functionality so customers could redeem included card credits during checkout while Stripe handled subscription and standard payment workflows.

Context-aware AI workflows

Built AI-powered customer workflows using the OpenAI API and Claude API, including an MCP server that provided agents with user context such as subscription tier and available card credits.

Platform integrations and delivery

Developed AWS Lambda services with Kysely, integrated Meilisearch and USPS delivery estimates, and improved CI/CD and local GitHub Actions testing with OIDC and act.
