I am a data scientist that helps make large distributed systems more resilient and self-optimizing.

What I'm looking for

I am looking to solve difficult, interesting problems that make a difference. I write and ship production quality code, and I want this code to implement innovative algorithms with sound mathematical foundations. I want to make large distributed systems more robust and self-managing, better at taking evidence-based autonomous decisions.

My specialty is the application of optimisation to the solution of applied problems. In the past I have done so in the context of network capacity planning and video quality of experience; more recently, in the context of statistical estimation and network traffic engineering. Depending on the problem I sometimes approach data science by formulating an optimisation algorithm in terms of the data and solving it, on other occasions, by simply using libraries as black boxes. I have always practised data science while embedded in software development teams, sharing their methodology and pushing code into production systems. In that sense, it could be equally argued that I am a software engineer with ample specialisms in optimisation and data analysis, or that I am a data scientist with ample experience with designing, building and deploying software into cloud-based production systems. Finally, my experience in academia has helped me to explain complex concepts clearly and succinctly, and to manage long-term projects with uncertain outcomes.

Principal Data Scientist

Apr 2016 - Jan 2023 (6 years 9 months)

In practical terms, my work helped Fastly improve fleet efficiency by co-optimizing infrastructure capacity and service performance. To achieve this I coded machine learning algorithms in Go, Python and jinja-driven multistage SQL pipelines running on Bigquery and orchestrated using dynamically generated DAGs using Google Cloud composer (Airflow). I also focused on demistifying ML within devs.

Data Scientist


Feb 2013 - Apr 2016 (3 years 2 months)

My work in Sky revolved around creating reusable components to automate decision making and plan execution for network capacity planning. I created a traffic-matrix forecasting component that fed a what-if network simulator that analysed multiple failure scenarios; the results were used to plan for CDN and peering/transit capacity. I also helped model how video impairments harm user engagement.

Research Associate

University College London

Feb 2010 - Mar 2013 (3 years 1 month)

My research encompassed novel Internet protocols and mathematical models, aided by purposefully- built network simulation, measurement and analysis software. I helped tutor MSc and PhD students, define research strategy and delivery of research outcomes, wrote research proposals, and collaborated with industry partners.

Feb 2001 - Sep 2005 (4 years 7 months)

My work allowed large telecom companies to better understand their network performance by developing and integrating network failure and performance management software components in Java and Perl.
