Working on the core sync engine, the heart of the Dropbox desktop app, 100% in Rust.Highlights: Started performance measurement sub-team. Saved over $250k / year in compute andstorage costs by rebuilding observability tools to use metrics instead of events, and by finding andremoving unused test suites. Halved primary and secondary on-call queues. Fixed all Rust lints,across teams and projects. Started CPU micro-architecture reading group.

[Remote] Easy low-latency screen sharing (try it!). Y Combinator funded. Very small distributed team. Screenleap is a low-latency distributed system for state sharing.Principal developer of back-end services (Go), WebRTC conferencing server (Rust), web front-end(Typescript), Ops tools, and integration and end-to-end tests.Highlights include building a video encoder with ffmpeg, building server auto-scaling tools, and auditing the whole platform for security (many defense-in-depth improvements). With founder,handled all releases and production SRE (CentOS, Prometheus, Packer, etc).Quadrupled daily screen share numbers, reduced share latency from multi-second to milliseconds, scaled to hundreds of live viewers. Customers say: ”absolutely the best of its kind”, ”easy to operate and marvellously efficient”, ”easiest screen sharing app”, ”my clients absolutely love it. wish I had used this years ago”.

[Remote] We built Nitro, the instant messaging server (XMPP and SIP protocols) which powers Eikon Messenger, the busiest chat system in finance (6 million messages / day). I wrote the bulk of the XMPP side (Go), working in a distributed team of six.Nitro is a cluster of servers running our Go application, with Redis and MySQL storage. Highlights for me have been implementing zero-downtime restarts, faster inter-cluster messaging, pure-Go XML parsing, implementing tens of XEPs (the XMPP equivalent of RFCs), and handling major refactorings in an extremely change-averse environment.

[Remote] Lincoln Loop are the Django experts. For our clients I did full-stack work web work, from system administration and performance (Ubuntu Linux, MySQL, Redis), up through back-end (Python w/Django, Go) and front-end development (JS w/ jQuery and Backbone, CSS3, HTML5). Major clients I have worked with are Future Publishing (for GamesRadar.com) and Broadway.com.I also wrote for the Lincoln Loop blog on topics such as the psychology of motivation, SPDY (nowHTTP/2), and WebRTC.

[Remote]. Acquired by Local.com"Find new things to do and places to go based on recommendations from people like you. Save all your product and place reviews in one place. Share with friends.”Two year freelance project, doing everything from server (Ubuntu Linux) and database (MySQL) setup and admin, through Python / Django development, up to the Javascript front end and the HTML / CSS. A Python daemon, connected to the site via Gearman, computes similar users,calculates recommendations, and pulls and pushes data to / from Facebook, Twitter, Amazon, and many other sites.

Start-up I co-founded focused on pro-environmental behaviour change. As the technical co-founder,I did everything except the design: Hosting and database setup and management on Linux and MySQL (at Linode), Python / Django back end development, and Javascript / jQuery / HTML /CSS front-end development. I also dug deep into social psychology and behavioural economics, as applied to web-based systems.

In a team of two, we designed, built and maintained all of KBCFP’s web and server-side applications.We built a trading / reporting application for the new Fund Derivatives (Funds of Funds) businessin Java / Struts / Hibernate. We designed test-first using JUnit and mock objects, coded as a pair,and interacted with the key users as we went. Aside from the browser, the server has a Swing client which talks COM to Outlook, and clients/interfaces in Excel, C# and Jython.I introduced Python and Django, with which we built an application for H.R. to handle all the firms recruitment, the KBC AIM and KBC Alpha hedge fund sites, and several others. We managed our own Linux and Solaris servers and MySQL databases.
