Work Experience

Staff Software Engineer at Credit Karma, London

Since July 2019 to now

I am attached to multiple teams to provide platform and product engineering leadership. In recent months, I have led the UK team’s migration from Linkerd to Envoy and I have led the implementation of features to comply with GDPR.

My current area of focus is platform security and data encryption using Gemalto’s hardware security modules.

Senior Software Engineer at Deliveroo, London

From September 2016 to July 2019

At Deliveroo, I played an instrumental role in multiple projects.

In the Logistics Algorithms team, I worked closely with data scientists on Deliveroo’s famous rider dispatch algorithm - Frank; soon afterwards, I led the design and development of the company’s first framework to train statistical models - Canoe.

In the platform team, I reduced datastore costs, built load-source observability, and helped transition from monolith to service oriented architecture.

My last few months were spent in the Payments group, adding support for new payment providers and improving the build-times of the central monolith.
