Employment Experience
|
Mar 2017 - |
OLX Senior Site Reliability Engineer |
|
Sep 2016 - Feb 2017 |
Gaikai Site Reliability Engineer Worked on upgrading internal monitoring and alerting platform, and trying to drive new methods of managing and configuring systems. Also responsible for day-to-day management and on-call handling, and trying to improve post-incident fixes to underlying systems. |
|
Jan 2016 - Jun 2016 |
Brandwatch Contract Senior Systems Engineer Hired to upgrade the HDFS and HBase versions for Brandwatch's existing installation, I built a completely new management platform allowing us to spin up and manage new clusters, and migrate to an install on the newest HDFS versions. We couldn't execute the planned HBase upgrade, because of application code changes and other priorities at Brandwatch. This management platform allowed easy spin-up and operation of different test clusters for Solr as well as HBase. I also introduced code-review to the systems team using Phabricator. |
|
May 2014 - Dec 2015 |
Apple (UK Ltd) Senior Big Data Operations Engineer As an early part of the Hadoop SRE team at Apple, we had to take over the running of existing clusters and applications from vendor consultants. As our team grew we were supporting multiple services on MRv2 and Spark, built on YARN, HDFS and Azkaban. Using techniques from Facebook, I built advanced telemetry to get and visualise high-quality data about the operation of the clusters. I also started to design and prototype a scaled monitoring system based on what I'd seen and learnt at Facebook. |
|
October 2012 - February 2014 |
Facebook, Inc Production Engineer I was part of the team managing the operational side of Facebook's production infrastructure for its 70+ HBase databases in 8500+ servers. These databases were the data storage for the 10bn+ messages a day in Facebook's messaging and chat application, and for much of the internal monitoring data. As well as ongoing maintenance, we built software to detect and remediate problems earlier and in more automated ways, and to better allow us to monitor and tune and configure the databases. |
|
April 2008 - August 2012 |
British Broadcasting Corporation Systems Engineer/Technical Architect (Senior Software Engineer) During 4 years at the BBC, I started on their post-broadcast VoD service (iPlayer), and then moved to consult on all areas of the BBC website. On iPlayer, I designed and implemented systems relating to content publishing, statistics and DRM licensing, and across the BBC I rolled out a refreshed implementation of the Zenoss monitoring, and consulted in systems design and operational supportability for product owners, as well as trying out new designs for the website as a whole. |
|
March 2005 - April 2008 |
Venda Ltd Senior Developer / Senior Systems and Networks Administrator I started off as a developer on the Venda codebase, and having worked extensively on optimisations and new features, was able to move, in October 2006 to their Systems team. There, I helped implement several network improvements, as well as leading operational maintenance tasks, and engineering several new systems. |
|
April 2001 - March 2005 |
The Bunker (previously A L Digital) Software Developer and Network Manager In nearly 4 years at A L Digital (now replaced by The Bunker Secure Hosting), I was involved with many projects, many concerned with security, and later on in terms of building and maintaining networks and network devices. As a programmer, I was involved with security, both writing SSL libraries and doing security reviews (including one on OpenSSL), as well as web application work carried out by A L Digital. |
|
July 1999 - April 2001 |
Codix.net Software Developer and Systems Administrator In July 1999, I helped Alex Nunes start up Codix.Net (since, a part of Venus Internet) by setting up the internal network, procedures and development environments. I wrote much of codix's infrastructure, including a small templating system, a cryptographic session-management system, and I co-wrote a small-scale fast search engine. I was also involved with much of the web application work done by codix. |
