What I'm looking for

I’m looking to build and harden reliable, event-driven backend platforms—owning high-throughput pipelines, driving reliability standards, and improving incident response with measurable uptime and performance gains.

I’m a Backend Software Engineer with 4 years of experience architecting reliable, event-driven systems for multi-tenant SaaS products. I combine deep, hands-on ownership of high-throughput pipelines with cross-team technical leadership—defining engineering standards, driving reliability initiatives, and raising the quality bar across integration-heavy backend infrastructure.

I’ve scaled production systems 20x under load, including building Thena’s Slack-native event ingestion backbone and improving throughput from 5K to 100K+ daily events with zero message drops at 500K peak load. I’ve also delivered measurable outcomes like reducing p99 latency from 30 seconds to under 2 seconds, cutting unplanned downtime by 70%, and improving incident response from multi-hour events to under 30 minutes through runbook-driven protocols and distributed tracing.
