Professional Profile

I am a senior developer with 15+ years' experience. I started out as a web designer before moving into back-end systems development.

My core technologies are Javascript (ES6 & node.js) and PHP but I also have commercial experience with niche languages like Clojure & ClojureScript (that expanded my knowledge of functional programming, concurrency and strict management of application state).

I've worked in Agile teams and on waterfall projects; in start-ups to medium sized businesses, as project technical lead or systems architect.

Innately curious and a life long learner, I enjoy acquiring new skills to deliver great software solutions. I like to stay current by listening to podcasts, reading online tutorials or taking MOOC courses (e.g. Cousera, udemy or Plural Sight).

What I can do

My skills

JS ES6 / Node JS / Express

I'm proficient with Node JS and have built RESTful web services & APIs (Express) and daemons listening / publishing to message queues. Several of those web services were level 3 REST APIs employing JSON media-formats.


I've 10+ years experience with PHP & MySQL / Maria DB. I've used full blown MVC frameworks and micro-frameworks (Silex & Slim), utilising SOLID design principles and automated testing (PHPUnit) for many years.

Rabbit MQ / Distributed Systems

I've built multiple distributed systems using Rabbit MQ to provide co-ordination, decoupling and horizontal scalability. I've experience with queues, topics & exchanges and know how to tune for throughput or resiliency.

Amazon Web Services

I championed AWS adoption in previous roles. This site uses AWS Lambda for the contact form below. I'm familiar with AWS API Gateway, Route 53, KMS, SES, Console and CLI tools.

Linux (Cent OS / Ubuntu)

I have 10+ years Linux experience. I'm proficient on the command line (bash / zsh) with Ubuntu & Cent OS. I have experience installing & configuring Apache, nginx, MySQL or where needed compiling from source. I use Linux Mint on personal machines.

Git / CI / JIRA

I've used git since 2009; SVN before then. I've used the git-flow branching model on larger projects & have configured Jenkins CI for fast feedback & SonarQube for static analysis. I've used JIRA & Confluence to track progress & document features.

I'm looking for my next opportunity.

I'm looking for a permanent role within a 25 mile radius of Hitchin, Hertfordshire.
