At SB&G I came to build a new cross-functional squad with the aim to develop our own in-house in-play football trading capabilities. This capability was something which SB&G had previous relied upon 3rd parties for and was a risk to the business. Over a number of iterations we created a highly flexible, highly available application built using AWS serverless services, Lambda, SQS, SNS, Api Gateway, DynamoDB to name a few.

During this time I was a technical team leader for the squad and a line manager to the members of squad with the greatest development focus.

Apart from being a web developer, I enjoy most of my time being outdoors. In the winter, I am an avid skiier and novice ice climber. During the warmer months here in Colorado, I enjoy mountain biking, free climbing, and kayaking.

When forced indoors, I follow a number of sci-fi and fantasy genre movies and television shows, I am an aspiring chef, and I spend a large amount of my free time exploring the latest technolgy advancements in the front-end web development world.
