👋 About Me

I'm a Software Engineer on the Infrastructure team at Chime. My work primarily involves building and maintaining highly available and scalable systems using AWS, Kubernetes, ArgoCD, Datadog, and Terraform.

I mainly code in Python and Bash, with some experience in Ruby and Go.

I write about infrastructure and engineering on my blog.

Most recent blog series:

  1. Streaming LLM inference on EKS — the build: VPC, EKS, vLLM Production Stack, and the streaming gateway.
  2. How much can two L4s serve? It depends on the prompt. — capacity, prefix caching, and the methodology trap.
  3. Per-tenant concurrency caps — protecting well-behaved tenants from a bursty neighbor.
  4. Adaptive concurrency on a multi-tenant vLLM gateway: WFQ + AIMD against a TTFT SLO — the self-tuning gateway.
  5. Autoscaling a GPU Fleet on Inference-Aware Signals - 🎢 ↔️

I've also shared insights on Chime's engineering blog:
