Senior Software Engineer

Almost seven years building across biomedical, e-commerce and cloud computing.

Most recently at AWS, working on Lambda's control plane. I'm drawn to computer networks, distributed systems and network security — and I like understanding a thing by taking it apart.

Currently on a career break — see what I'm up to now.
