Peter Zhang — Portfolio (v3)

Experience

Places I've shipped
real things.

A few of the teams I've shipped real code with — from RTOS graphics drivers to AI-powered video pipelines. Open any role to see the highlights.

Built Medic, an internal AI Slackbot that triages brand health on demand through Snowflake and MongoDB — eliminating manual dashboard lookups for on-call engineers and saving ~20 min/query across the Guest App and Launch teams.
Shipped a full-stack address-deletion feature (GraphQL endpoint + mobile UI), then wrote a remediation script that purged orphaned address entries across the production MongoDB instance.
Leading productionization of the Guest App mobile catering flow — entry points, deep-link routing, fulfillment scheduling constraints, and checkout — promoting a spike PR stack to production with finalized design specs.

Rolled out a shared OpenTelemetry SDK across the Finks service fleet, replacing logfire and wiring EventBridge error-event publishing across multiple Python services.
Built Auxo Studio, a multi-surface content automation platform for the Finks creator program — a Rust/Tauri desktop app, a Rust MCP server, and a Vercel-hosted frontend backed by an AWS EC2 service — automating 3 Instagram carousels a day and saving ~1.5 hours of manual content work daily.

Engineered a cross-service RBAC system (Ruby on Rails, Bun/TypeScript) for 30k+ users, unlocking Fortune 500 compliance and enterprise-tier adoption.
Led a 3-developer squad to deliver the AI Video Backgrounds feature in 5 weeks, owning the full SDLC from systems design to production deployment.
Reduced media rendering failures by optimizing AWS Lambda timeouts and configuring Datadog alerts for the video generation pipeline.
Enforced data integrity across HubSpot/Zapier integrations by implementing granular permission scopes within the microservices architecture.
