Key Contributions

  1. Edge Architecture: Architected edge microservices on Cloudflare Workers, cutting infrastructure costs by 60% versus VM deployments with near-zero cold starts at $400/month projected for 1M MAU.
  2. API Performance: Optimized GraphQL API to 120ms P95 latency at 5K RPS using Houdini client caching and Pothos persisted queries, reducing payloads by 45%.
  3. Notification Mesh: Designed multi-channel notification system orchestrating in-app (GraphQL Subscriptions, SSE, Durable Objects), push (VAPID/ECDH), and email (Postmark) with 99.9% delivery reliability.
  4. Search Engine: Built search and recommendation engine with PostgreSQL + Drizzle ORM using tag-weighted scoring, delivering sub-200ms results on 1M+ rows.
  5. Video Streaming: Implemented video infrastructure with Bunny.net HLS, custom Vidstack player, adaptive bitrate, and signed .m3u8 URLs, cutting buffering events by 80%.
  6. Session Management: Built session system extending Lucia v3 with custom Redis adapter (ioredis-Upstash), achieving sub-5ms lookups at $0.02 per 10K operations.
