Technical Lead - Data Platform

As a technical lead software engineer, I enjoy tackling large scale data challenges.
Designing distributed yet simple systems is something I am passionate about. Constantly learning about new technologies, approaches and problem solving skills makes this always evolving field exciting.
I take pride mentoring juniors so that they see the value of shipping quality software, building clean architecture and reducing operational complexity.
