AI shopping marketplace
MixR
Full-stack developer, full-time (Mar 2024 - Aug 2024)
MixR is a community-first marketplace where an AI agent finds products across stores and checks out for you. I built the Go, PostgreSQL, Redis and GraphQL backend, the agent-friendly APIs, MixR Pay on Privy wallets, Shopify sync through Rye, trigram search and Docker Compose deployments with CI/CD.
What it does
- Go services on PostgreSQL, Redis and GraphQL behind search, catalog sync and order flows.
- Agent-friendly APIs so the AI shopping agent can read and act on them reliably.
- MixR Pay, a crypto checkout on Privy embedded wallets that lets the agent pay on-chain.
- Shopify catalog sync through the Rye API, with Redis caching and PostgreSQL trigram search.
- Docker Compose deployments with CI/CD on a VPS.
