Trainline at Silicon Milkroundabout

Some of the Trainline team at Silicon Milkroundabout

A few weeks ago I was lucky enought to be part of the team that tried, and hopefully succeeded, to entice more developers to come and work with us at Trainline at the Silicon Milkroundabout tech recruitment event.

I really enjoy talking to people about technology and it was especially nice to talk to people who were genuinly interested in what we do at Trainline. Some, who were also recent graduates were especially interested in how I got my job and what I do in my day-to-day work — I reccomended that a lot of these people try events like HackTrain.

Like all cool tech companies we had merch to give out to people. My particular favourite was a Trainline ticket holder, which replaces my standard National Rail one and looks like it will be much easier to find due to its nice bright colours!

As well as nabbing some of the march, I also managed to get my hands on a Trainline Staff Polo, as beautifully modelled below:

On-boarding at Trainline

Trainline Homepage

I’m now entering the sixth week of my time at Trainline. It’s been quite the experience, due to it being my first full-time job and it being a time of significant changes at Trainline in terms of technology, branding and even an expansion into the European rail market.

It’s been great to be in a team of people who know so much about Software Engineering and the systems in use at Trainline, and whom are so willing to pass that knowledge on. I’ve also been blessed with some really cool projects to work on at the start of my trainline career. The first thing I was tasked with doing was replacing the standalone Best Fare Finder application, with deep links to an improved Best Fare Finder experience which was already built in to the main ticket purchasing flow.

The Best Fare Finder allows you to find the cheapest tickets avaliable between two stations if you’re willing to be flexible on dates and times of travel

The Standalone BFF, pictured above, wasn’t responsive; didn’t look like the the newly rebranded trainline homepage and purchase funnel and required additional maintenence. Removing it and using the best fare functionality baked into the main purchase flow improved the experience for users and reduced the costs, both financial and of technical debt, to the company. The inline best fare finder which replaces it can be seen below:

The pictures of popular locations you can see in the screenshot of the homepage, or Roundals as I’ve started calling them (inspired by the name of the famous Tube logo which is a similar shape), had to be updated as part of this work. This was quite exciting as it meant that within a week of my first job I had pushed a change, albeit relatively minor, to the home page of a website with millions of visitors a month. The deep linking I developed for this inline BFF is now also used in Trainline emails to customers.

As part of doing this work I discovered that some parts of the Best Fare Finder backend were a bit difficult to work with and that access to useful information could be greatly simplified leading to a reduction in the number of places in which static data was manually updated by humans. I proposed that a RESTful API was developed with some easy to understand endpoints that delivered a JSON response.

My development manager and product manager were supportive of the idea and therefore I started working on a set of requirements and use-cases for the product, which I simply called BFF API (Best Fare Finder Application Programming Interface). The resulting system is written in Node.js 4 — making great use of all the new features of ES6 such as block scoping, destructuring and arrow functions — Hapi.js and an assortment of the libraries avaiable from npm.

It is unlikely that this system will be made user facing itself, but it may contribute to some of the things a user can see from the backend.

I’ve learned rather a lot in the last few weeks: including the business and technological processes involved in developing enterprise quality software, how to navigate through and modify/maintain legacy systems and some more about the Node.js ecosystem. Expect a blog post in the new few weeks about how I’ve changed the way I develop Node.js code in order to aid correctness and the ability to tests things.

Whilst some parts of the transition from academia to Real Life™ have been difficult to get used to (what is waking up at 7am and commuting?!) overall I’m enjoying the new experience and feel like I’m learning as much or more than I was at university and being paid to do so — the best of both worlds!

I will keep the blog up-to-date with my progress at Trainline.

All aboard the Employment Train

One of the questions I had to answer for both myself and interviewers was “What do you want to achieve in your first job?”. My answer was always a quote I read on a blog by a programmer hero of mine, Jeff Atwood. He said you should, as a junior software engineer, “endeavor to be the dumbest guy in the room” which simply means place yourself around intelligent experienced programmers and learn! This is what I wanted to do and I’ve been fortunate enough to be hired by a company that has an environment that will allow me to do that – thetrainline.com.

thetrainline.com sells train tickets in the UK and Europe both from its own website and by providing the software for Train Operating Companies such as Virgin Trains and First. They operate out of an office in Farringdon, one tube stop from London Kings Cross station.

I start in late September and honestly cannot wait to learn and earn with them. My official job title will be “Agile Developer”.

A big thank you is in order to Teck Loy Low who I met on The Hacktrain and subsequently put me in contact with thetrainline. If this isn’t a good advert for getting yourself involved with hackathons and the like I don’t know what is.
