Event Pipeline
Go microservices moving 100M+ ad-tech events a day at Mable.ai.
Open to contract & full-time roles
Hi, I'm Piyush Pandey, a software engineer.
Currently at Mable.ai, shipping Go microservices for the ad-tech pipeline. I like distributed systems, observability, and writing code the next engineer can read.

A note on what I do.
I'm a software engineer working on event-driven backends, the kind that quietly move a hundred million messages a day and aren't allowed to drop any of them.
At Mable.ai I build Go microservices for the ad-tech pipeline: ingest from Meta, TikTok, Pinterest and Shopify; transform, attribute, persist. The work lives across GCP Pub/Sub, Postgres, ClickHouse and Redis, instrumented with Prometheus and Grafana so failure has a face.
Before that, telemetry at UIDAI and a brief stint in frontend at Omikron. I care about latency budgets, error messages, and treating the next engineer with respect.
