I’ve worked in the financial services industry most of my career, with companies such as Goldman Sachs and more recently
Credit Suisse. Putting it simply, I specialise in getting stuff done. I sit right in the middle of a bunch of agile
development teams, and I help them to get their own stuff done quicker and better than they could if I wasn’t there.
If you’re not into reading long resumes, read the following few bullets for a whistle-stop tour of what I’m good at:
- Linux (RHEL, Ubuntu) and Windows Server administration.
- Deployment and configuration management with Ansible.
- Scripting with Bash, Powershell, Batch.
- Development with Ruby, Ruby on Rails. Hacking on anything else thrown my way.
- Monitoring servers and applications with tools such as Collectd, Graphite/Grafana, InfluxDB, Splunk, Monit, Consul, Nagios.
- CI with TeamCity, version control with Git, SVN, Stash, Github Enterprise.
- Multi-region team management, including hiring, performance reviews, objective setting, workforce reduction

Credit Suisse - January 2015 - present
Vice President, Platform & DevOps Engineer, Equities Risk
I run DevOps (i.e. “Getting Stuff Done”) for the Equities Risk division.
- Management of a 1000+ server estate consisting of both physical and virtual servers, split approximately 85% Linux,
- Configuration management of infrastructure and deployment of software using Ansible.
- Physically located within an Agile dev team - involved in multiple daily team standups, production issues,
iteration planning. Work closely with devs and operations teams to attempt to break down traditional banking “siloed”
- Monitoring and capacity analysis using Collectd, Graphite, Grafana, Monit, Nagios. Built relevant dashboards to
monitor JVM & HTTP based applications. Understand the intricacies between monitoring VMs and physical hardware.
- Maintenance of deployment scripts in Ruby, deploying to both Linux and Windows hosts.
- Performance tweaking of Windows and Linux infrastructure to maximise throughput for JVM & HTTP based applications.
Some of the larger projects in this role:
- Managed and executed replacement of 600 virtual RHEL Linux servers and application migration to 150 physical
servers, for purposes of cost reduction, reliability and performance consistency. Post provisioning configuration and consistency checks were carried out via Ansible. Servers were split for use by multiple services using c-groups.
- Development of automated deployment tool for dev, UAT and production environments using Teamcity and Ansible.
Allows new services to be deployed and released simply by developers including an Ansible playbook within a build package.
- Development of a service “baseline”, consisting of a repeatable set of tools for use by new services; Ansible
for deployment, Collectd and Graphite/Grafana for metrics, Splunk for log collection, Nagios/Monit for monitoring
and Consul for service discovery.
Credit Suisse - May 2011 - December 2014
AVP, Environment & Release Management, Equity Derivatives
I managed the Release and Environment Management team at Credit Suisse, a team of eight, split across multiple
regions. The team is responsible for all software released into the Equity Derivatives division, the infrastructure
that it runs on, and the infrastructure used to develop it.
My role was extremely varied, but not limited to:
- Capacity and platform management - provisioning, decommissioning, capacity analysis. I lead the project to
introduce Nagios into Credit Suisse, which now monitors the entire Equity Derivatives estate.
- Technical consultancy - I worked closely with development teams to help them to select the best technology
and infrastructure for their application. This often involved introducing new previously-unapproved technology
into the bank and arranging approval for use.
- Strategic software development to assist my day to day role, e.g. scripting large scale software deployments
across multiple platforms.
- Release management - deploying the software produced by various development teams with Equity Derivatives IT.
I ran the team borrowing practises from common agile development methodologies. Rather than a weekly team meeting,
we had daily stand-ups and monthly retrospectives. With the high turnover of work, this allowed me to keep on top
of the teams’ upcoming deliverables ensuring targets were met.
