Who Am I ?

I am Paul Hammant, Senior Director of Engineering at HedgeServ.com, and oversee all software development. I have teams in New York, Boston, Ireland, and Bulgaria. Teams make applications and services with different technologies, different release cadences, but all are agile and rest on DevOPS + Continuous Delivery best practices.

I used to work at ThoughtWorks, and spent nearly all of 12.5 years there on client engagements (finaincial services, an airline, retail, startups). Roles ranges from developer, tech lead and Director of Engineering. Before ThoughtWorks, I was Head of Development at a UK M-Commerce startup. In the early 90's I was a freelancer on green-screen systems development in the insurance field. Before the turn of the millenia, I was developing fat and thin solutions for enterprise Java needs.

I’m a Brit in the US (Green Card), and in my late-40’s. I have mostly been a IT consultant since 1989. I’m an Agile advocate, and love open source development.



Dependency Injection Pioneer




I was rabid about Inversion of Control (IoC) long before I arrived in ThoughtWorks, or indeed before it was popular anywhere. I’m also one of the pioneers of the related topic Dependency Injection and guilty of defining some numerical sub-types for IoC, before ThoughtWorks’ chief scientist, Martin Fowler, wrote his widely-read article renaming what I was talking about to Dependency Injection (DI)

Back then in 2002, I was busy working on the first constructor injection DI container with Aslak Hellesoy (more famous for Cucumber these days) - PicoContainer, in Java.

Selenium Co-Creator




Selenium, is the defact-standard functional web-app testing technology. I’m co-creator of Selenium 1.0 (2004). The bit I did was Selenium-RC's browser process spawing side, to allow your choice of driving language, with your choice of browser (Firfox or IE, back then). That used a Comet mechanism, although it wasn't called that until later. These days Selenium 2 (WebDriver) is a huge force, with cloud testing grids, and just about every web-development team uses it. I was until 2016, in the Selenium management committee.

Flag Carrier For Trunk Based Development




I talk about “Trunk Based Development” (TBD) a lot. Enough so that you’d think I’m its inventor (I am not). Similarly associated practices, “Branch by Abstraction”, and Feature Toggles (or flags if you prefer). A lot of my cosulting career featured the recommendation of, and planned migrations towards TBD.

Branch by Abstraction - a technique for avoiding multi-branch development and the source-control merging consequence of that. Again, not the inventor (or even the fellow that coined the term), but the chief advocate for the practice.

Other Recurring themes

Aside from the above, there are some themes that I keep returning to in this blog over the years:

For the entire current millennia, I have been an advocate of Open Source, and eXtreme Programming (XP). I was participating in the former for a couple of years, before I became an advocate of the latter. The two communities feed off each other. Of course Lean and Kanban take over from XP these days, and I do what I can to avoid Scrum as well as correct people when they conflate it with Agile.
