During my time at SAS, I held the position of Full-stack Developer and was responsible for both maintaining and developing new features within our Java/Springboot APIs and Angular applications.

Sep 2021 – Jun 2022
I held the position of Cloud Developer at ASSA ABLOY, where my core responsibility involved the implementation of a Single Sign-On solution for one of the organization's customer-facing applications. As part of a dedicated team of three professionals, I played a key role in overseeing this migration process and was specifically tasked with the implementation of Auth0 into the existing React application. Additionally, I managed the user account migration from AWS Cognito to Auth0.
Cybercom – Full-time
Apr 2021 – Aug 2021
During my time at Cybercom, I had the privilege of serving as a consultant at Stockholm Toy Museum. Our team was tasked with the development of a smart stand that could dynamically manage the display and lighting through an Alexa skill. I was specifically assigned the responsibility of developing the Alexa skill that controlled the content displayed on the stand, while leveraging Google Drive to facilitate easy end-user management. The media utilized for this project was fetched using Google API and subsequently synced programmatically to Amazon S3 due to the limitations imposed by Google Drive. To achieve this, the media sync flow was triggered by the Alexa skill and queued on Amazon SQS, where an Amazon Lambda function took charge of the syncing process.
In addition, I was also involved in an in-house project called "Face Your Emotions", where my expertise in Angular proved instrumental in enhancing the overall codebase structure. The game entailed competing as a team to match facial expressions, which were analyzed using AWS Rekognition to calculate a percentage score. My contributions to the project involved introducing module structure, simplifying the logic behind the game, and ensuring optimal performance.
Cision – Full-time

Scania – Full-time
Sep 2017 – Jul 2019
At Scania, I was a member of the team responsible for developing and maintaining web applications utilized by Scania's Global Technical Support team and workshops worldwide. Specifically, I worked on an application that allowed workshops to update truck software, modify truck composition, and perform compatibility checks on component modifications. This application was initially developed using Angular 4 and later upgraded to Angular 6. Our backend was developed using the .NET/C# framework and designed as a RESTful API, adhering to industry best practices and standards.
During my final year at Scania, I led AWS migrations for both the frontend and backend parts of the system. To accomplish this, Gitlab runners were set up in AWS, and the repositories for the web applications were relocated to Gitlab. Subsequently, CI/CD pipelines were configured to deployed the frontend applications. The REST API was partially migrated and then segmented into smaller Node.js lambdas created utilizing the Serverless Framework.
