What I'm looking for

I’m looking for a backend/distributed systems role where I can own end-to-end architecture, build Kafka + Kubernetes pipelines, and measurably improve reliability and performance for multi-tenant platforms.

I’m a backend engineer with 5 years designing and operating distributed systems at scale in Python. I own systems end-to-end—architecting workflow-orchestrated execution platforms (Temporal, Argo Workflows) and async, Kafka-backed pipelines that serve 160+ enterprise tenants.

At Atlan, I drove a >93% performance improvement (11 hours to ~40 minutes) across 9,958 production runs by hardening pipelines with idempotency guardrails and circuit breakers. I also improved production reliability for 30+ enterprise accounts, independently triaged and resolved 11 P0 incidents, and built metrics-to-alerting using Clickhouse + Grafana; previously, at Cashflo, I delivered a 93 GB/day distributed pipeline and reduced processing errors by 99%, while mentoring a 4-engineer team.
