Software Engineer · Data Infrastructure & Platform Engineering
Profile
Software engineer focused on dependable data infrastructure and internal platforms, with experience spanning data architecture, engineering tooling, analytics engineering, and cross-functional software delivery.
My work has moved from software stability and release engineering into data models, internal data products, and platform-oriented systems. I value useful abstractions, operational clarity, and making reliable data easier for others to use.
