About

I'm a backend engineer with 5+ years of experience designing and operating distributed, cloud-native systems. My work spans real-time data pipelines, event-driven architecture, and financial infrastructure — from telemetry ingestion on large-scale infrastructure projects to production fintech platforms used by thousands of people.

Currently, I'm a Senior Software Engineer at Proqio, where I build backend services for real-time construction and field data ingestion, including 3D mapping and digital twin platforms for projects like NEOM. I care about systems that are reliable under load, easy to reason about, and built to scale.
