What I'm looking for

I’m willing to relocate globally and am preparing to pair with AI as a system engineer.

At Deustche Telekom, I developed the SDX WAN orchestration platform using Java and supported its deployment on AWS and OpenShift. I also worked on network feature design and UML specifications, and developed modules and client libraries.

I built and maintained services across my work at TestVagrant, Jaarwis Technologies, Ciena, Mitel Telecommunication, and Infosys Pvt Ltd. My projects included subscription services, ISP APIs, network configuration frameworks, and VoIP infrastructure.

I love automating boring stuff so I can focus on exploring unknown territory and working with greater precision and efficiency. I’ve also contributed to open source, including a web-based testing suite built with Robot Framework and Django.
