Senior Data Engineer at Yelp

Alireza Davoudi

I build the pipes data flows through: streaming, lakehouse and the cloud infrastructure underneath. Raw events in, something you can trust out.

How I think about data

From noise to signal.

Every platform I work on follows the same arc. Scroll to fly through it.

01/ 04

Capture

Everything starts as noise.

Databases, events and clickstreams never stop talking. I like the part where change data capture and event buses turn that chatter into a stream you can actually reason about.

  • Kafka
  • Debezium
  • EventBridge
  • Lambda

02/ 04

Process

Turn motion into meaning.

Streaming and batch compute that reshapes events at scale. Underneath it all sits plain systems work, so I enjoy pulling containers, CPU limits and autoscaling apart to see how they behave.

  • Spark
  • Flink
  • dbt
  • Python
  • Docker

04/ 04

Operate

Run it like you will be paged for it.

A pipeline is only as good as the infrastructure it runs on. Infrastructure as code, least-privilege access across accounts, and a close eye on the bill.

  • Terraform
  • CDK
  • CloudFormation
  • IAM
  • Systems Manager
