Who Am I ?
I’m Paul Hammant and in my mid-40’s. I have mostly been a IT consultant since 1989. I’m an Agile advocate, and love open source development.
I am Senior Director of Engineering at HedgeServ.com overseeing the development of polyglot systems for a hedge fund administration platform. We have development in New York, Boston, Ireland and Bulgaria.
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. Before that I was a freelancer on green-screen systems development in the insurance field, before being early in to fat and thin solutions for enterprise Java needs.
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 and correct people when the conflate it with Agile.

Minor claims to fame?
I was rabid about Inversion of Control 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 coining some numerical sub-types before ThoughtWorks’ chief scientist, Martin Fowler, wrote his widely-read article making the world of development good again.
Aside from Dependency Injection, there are some technologies/techniques I helped push:
- Selenium, and functional web-app testing. I’m co-author of Selenium 1.0, and unknowing pioneer of Comet, as part of that.
- Branch by Abstraction - a technique for avoiding multi-branch development and the merge-consequence of that. The technique leverages “Trunk Based Development” and “Feature Toggles”
Aside from the above, there are some themes that I keep returning to in this blog over the years:
- Pseudo-declarative UI markup languages, delivered over HTTP
- Trunk Based Development, Branch by Abstraction, and Feature Toggles specifically, and source-control best practice
- Things that are backed by Source Control, that are not normally
- Tier-reduction architectures, patterns and alike.
- Agile of course, with XP, BDD and ‘small stories’ in particular.
