I build the infrastructure that intelligence runs on.

SDE 2 at Microsoft, on Azure's data platform. Previously cellularized DynamoDB's US-EAST-1 region at AWS and built the SmartThings notifications platform at Samsung. Two patents. M.S. CS, USC.

The pattern I shipped at AWS: isolated cells cap blast radius; unhealthy cells are weighed away automatically. Hover a node · numbers are from production.

experience

Microsoft · SDE 22024 — now
  • Azure's data platform: durable, idempotent pipelines reconciling legacy data.
  • Information-theory health snapshots driving auto-healing container apps.
AWS · SWE2023 — 24
  • Cellularized DynamoDB's US-EAST-1 region into isolated failure domains; extended AWS SDK Java v1/v2 for the new topology (+30% reliability, −20% p99 latency).
  • Built elb/auto-weight-away: load-balancer management that pre-allocates surge capacity and weighs out affected LBs with no human in the loop (−10% peak latency, 90% of capacity ops automated).
MathWorks · Software Engineering Intern2022
  • Web-MATLAB performance on low-bandwidth connections.
  • Cut the JS test suite runtime by 3 minutes.
Samsung · Senior SWE2017 — 20
  • Built the SmartThings notifications platform.
  • Shrank the app APK from 150MB to 90MB.
  • Shipped a patented contextual widget on Galaxy S21.
  • Built multi-client RTSP streaming.
