Adam Guest

Polyglot Developer

I architect, build, and deliver software solutions that are usable, maintainable and effective.

Software development can be better, and I love to explore new and different ways to develop software that allow for faster feedback, greater robustness, and improved capacity to meet the needs of users. Whether through exploring new programming languages and technologies or by improving processes and ways of working to gain a greater connection to users and a sharper focus on quality, I find it exciting to discover the ways that we can be better at developing better software.

I'm based in Copenhagen 🇩🇰, speak fluent Danish and English, and I'm currently excited about working with F# and Swift.

Employment History

Senior Consutant

I work to build high quality software solutions with clients.

Cloud Developer

DFDS

NOV 2019

DEC 2021

I worked as part of a team developing a solution for monitoring and instructing autonomous vehicles working at DFDS locations in collaboration with other companies. The software solution comprised mainly of several .NET core microservices running in Kubernetes and communicated primarily via Kafka events, the team and I had a strong focus on using DDD techniques to establish bounded contexts and make use of a ubiquitous language across the project. As well as the backend part of the solution, I also contributed to the frontend monitoring page developed using React.

To facilitate demonstrations to stakeholders and to provide another option for testing the system, I developed an iOS app using SwiftUI and LocationKit that allowed me to simulate an autonomous vehicle operating in a given area - this provided both automatic position updates over SignalR as well as user defined actions.

As part of internal knowledge sharing activities I was actively involved in the developer book club, reading and discussing a number of books focused on software development. I also made several contributions to the internally developed, open-source library for working with Kafka events - Dafda.

Storytel/Mofibo

NOV 2017

OCT 2019

Originally working as a backend developer building microservices running in docker containers on Kubernetes on Google Cloud Platform. I developed several services in F# and C# - both HTTP APIs and services consuming Pub/Sub messages. Over time I moved into a more "full stack" role continuing to develop microservices in the backend, but also working on the iOS app (after teaching myself Swift) building functionality that made use of the new backend APIs (in Swift, using MVVM) and integrating it with some of the older parts of the codebase written in Objective C. As part of changing CI provider, I was extensively involved in improving the build automation for both backend services and the iOS app.

As I introduced F# to the tech stack, I also worked heavily with training and mentoring other developers - both to teach them a new programming language and a new approach to solving problems, but also helping to develop their existing skills. I was one of the co-creators of the dotnet template that allowed developers to get a new microservice up and running with standard configuration in either F# or C# with minimal effort. I also was a member of the API Standards group within the tech department that worked towards creating guidelines for how the API surface across many microservices should work.

Additionally, I was involved in several recruitment processes, including reviewing applications and running both social and technical interviews leading to several good hires.
