Real-time systems that don’t lose data.

Senior software engineer, 8+ years. I build telemetry pipelines and event-driven backends that stay correct under load — and ship them to enterprise clients.

ABSTRACT · Eight-plus years across telemetry, logistics, and enterprise platforms. At Tenderd (YC S18) I led a 7-engineer team to deliver the module that onboarded Saudi Aramco inside a hard <2.5-monthwindow, and migrated live CDC → Kafka telemetry across 200+ devices with zero event loss. Earlier: event-driven backends serving 5M+ users at Bykea.
