CTO & Technical Cofounder
Trakio Apr 2013 - Dec 2015
Achievements & Responsibilities
Driving our customers' activation & reduce churn by understanding their users better. Executed a number of pivots searching for a repeatable & scalable business model. Each time creating hypotheses & testing them.
As the CTO I was responsible for planning, building, managing, & documenting several production services & client libraries from scratch. I implemented the provisioning of our hardware infrastructure on AWS using Chef, along with service monitoring & redundancy, having had no previous experience of SysAdmin. I recruited & managed all our technical employees & contractors, managing their on boarding, training, & providing direction & mentorship for their personal development. Utilizing online tools to collaborate remotely, often across timezones.
Working on Trakio has been the single most informative period of my life. Coming to San Francisco, interviewing for YC, taking part in the Alchemist Accelerator, experiencing nacho "cheese", the people I have met, the lessons I have learned. It has been eye opening to say the least.

CTO & Technical Cofounder
Virally Jun 2012 - Apr 2013
Achievements & Responsibilities
I conceived & delivered a working prototype as a proof of concept inside of two weeks. I led & managed the team that then fleshed this concept into an off the shelf solution to generate & manage leads from long form content marketing. The product we built enabled customers to achieve conversion rate increases of 122-200%, & secured us a 6 month up front contract with GFK.
While at Fruitbowl, a client came to us with a problem. We immediately saw the resell value in the solution & spun it out into its own startup: Virally, a lead generation tool for companies with downloadable content marketing. It uses social network authentication to easily & seamlessly submit users' details in return for valuable downloadable content.
My cofounder & I realized it was heading in a direction that we weren't passionate about, & had limited long term sustainability issues with increased public awareness around privacy & personal data. We both sold our stake in Virally to our investors to start Trakio.

Senior Consultant & Lead Developer
Fruitbowl Media Mar 2012 - Aug 2012
Achievements & Responsibilities
I increased the size & breadth of the company's portfolio by adding more advanced web application work. I built a team capable of delivering this more complex work by recruiting an additional designer & developer, & training existing staff.
I started working with Fruitbowl Media as a freelancer in November 2011, & it wasn't long before they asked me to join them full time as lead developer, to expand their current bread & butter of static marketing sites toward larger web application projects.
I wasn't at Fruitbowl long before we decided to spin out one such project we were working on with a client into its own fledgling company.

Web Developer
University of Kent - Web Development Team Nov 2007 - Mar 2012
Achievements & Responsibilities
I built & maintained several key systems including the University's password reset system, on boarding for new students & online maps. I successfully managed the implementation & launch of the University's student fee gateway by a 3rd party vendor, a service that processes tens of millions of dollars worth of tuition each year. I oversaw the transition of the main marketing site's web framework, a key component of the University's web presence, to this team. I led the adoption of agile processes, working to refine a scrum based process that allowed us to be an agile team within a slow & bureaucratic department. I implemented & consulted on several user experience improvements across various teams & services which contributed to a raise in our student satisfaction rating, the key performance metric for our department.
After graduating I moved from my part time roll into a full time position, & switched to a team that was responsible for many of the University's online web applications.
I am most proud of the transition the team made during the time that I worked there, & my contribution to that transition. When I started we were a poorly performing team with very little coherence, struggling to deal with the bureaucracy of the wider organization. By the time I left we had implemented continuous improvement & evolved our own flavor of agile scrum that allowed us to function most effectively given the constraints of the environment in which we operated.

Web Developer/Designer
University of Kent - Departmental Web Support Team Nov 2005 - Nov 2007
Achievements & Responsibilities
I lead the work of translating an established print based design & branding to the web for use across a range of uses & departments. I implemented that design into a flexible PHP/CSS based template that was successfully rolled out across dozens of departments & publishers managing content on https://www.kent.ac.uk. I successfully project managed the adoption of site template upgrades for several large departments, & account managed several others. I was promoted twice during my two years in this team.
Given how long I'd been experimenting with web technologies for, my university studies did little to challenge me & so I found a part time job for the University as a designer/developer in their fledgling Departmental Web Support Team. We worked with departmental web teams to deliver their web sites under a consistent brand.
Early on I was given the opportunity to work on creating a standardized template that could be used across the large number of academic & nonacademic departments. I was the main designer & developer on the first 3 generations of this centralized template. & contributed to later versions of the framework as a senior developer as part of a larger team.
I progressed within the team, starting as a part time junior designer to working full time hours as a senior designer/developer. As a senior, I was responsible for mentoring & supervising junior staff & project managing the development of departmental web projects.
Over the years that I worked on the system we evolved it into to a PHP framework that allowed departmental editors to write HTML in Dreamweaver as they were used to. We would post process their HTML to build advanced dynamic UI elements that would not otherwise be possible with Dreamweaver alone.

Macromedia Flash
Nelson's Leavers Interactive Yearbook Academic Year 2003/04
An interactive Flash application presented on a DVD data disk. With farewell messages, photo galleries, videos & easter eggs. Developed & produced during my last year of high school, mostly for the love of it, but with a nice little profit at the end.
The web back then wasn't what it is now, & I was frustrated with the limited interactivity of web pages, so I turned to the only place there was to turn in 2003: Macromedia Flash!
Along with two like minded friends we finished the project on time & made ourselves some beer money for the summer. Most importantly though, I learned things that were far more valuable given my future in software engineering than anything I learnt in class.

- ActionScript
- Photoshop
- Video Editing
I Catch the Programming Bug
Operation Flashpoint Released Summer 2001
Writing custom mission scripts for Operation Flashpoint was what first really got me into programming. I probably would have found my calling with out this game but even so I owe a lot to it for first igniting my passion for programming.
When I purchased a copy of Operation Flashpoint it was as "just another game" but when I discovered the scriptable mission editor I was hooked. I'd used PHP before but only as a templating language, this was something else entirely. I could make characters move across the virtual map engaging each other at my whim, I was hooked!
From here I started exploring more & more of the potential of PHP as a programming language. Building the foundation for a passion for making things, which is as strong today as ever.
Royal Hospital School
GCSEs & A Levels (UK High School) Sept 1997 - July 2004
My high school education lacked any formal programming education but that didn't stop me learning. I spent a lot of (my teachers will say too much) time tinkering away on my own web projects.
The Royal Hospital School, is an income assessed private boarding school with a strong naval tradition. Boarding with boys & girls from a wide range of backgrounds has given me many insights & oppotunities I simply would not have had access to at any other school.
Extra curricular activities like the Combined Cadet Force & the Duke of Edinburgh Award have provided me with the skills & resilience to prepare & deal with most of what life has had to throw at me.
Boarding from the early age of 12 & being away from my family has meant that from an early age I have had the self discipline & independence to work well on my own. Whilst the comradery & nature of boarding have instilled a great appreciation for working as part of a team.

Example Code
A Typescript library for automatically mocking HTTP requests based on their contract schemas.
A Ruby on Rails & React app for the required documenation for distributing live plants within the UK.
Not technologies I'd use if I was starting today. But I'm a pragmatist at heart & if it aint broke don't fix it.

Other Interests
I understand the importance of a balanced lifestyle, & have many interests beyond software development. Here's how I like to recharge:
Being a Dad
I say being a Dad but really I mean vicariously reliving my childhood, going to scouts & playing Lego.
Building Models
At my core I like to build things, building software is incredibly rewarding but sometimes it's nice to work on something physical.
Hiking & Bouldering
I love being outside & away from the city. Southern California has so much to offer close by & I'm just starting to scratch the surface.
Snow sports
I'm a proficient skier & a distinctly average boarder. California wasn't the best move for snow sports but one day I'll make it back to the slopes.
