The assignment aimed to help the church to modernise the church election process in Sweden by transitioning from traditional paper forms to a fully digital signup system. Working with an agile team, we extended the existing web-based group and candidate system (GKAND) to facilitate this transformation. By integrating BankID for secure digital signatures, we ensured the signup process and management of candidates to be significantly faster while increasing security and integrity of the entire process. The new system is expected to be used by over 27,000 candidates which will significantly reduce the administrative burden.

The group and candidate system is used to manage tasks before the church election, including the collection of personal data for candidates and the generation of ballot papers. The latest version of the system from 2017 suffered from performance issues; users sometimes had to wait over a minute for a response. Christopher joined the project as a team lead with the mission to migrate the frontend from Angular to React, where he implemented Next.js to improve the responsiveness and efficiency of the user interface. The result was a dramatic improvement, with response times reduced from minutes to milliseconds. The new component system has also laid a strong foundation for future development.

The candidate display is a web app that allows people to digitally see which candidates are running in the Church election. It is a digital way to see whom you can vote for. Christopher was responsible for leading a junior colleague in the migration from Angular to React with NextJS. Christopher helped set up the CI/CD pipeline, oversee prioritizations, and connect data retrieval via APIs. The migration laid a strong foundation for further development.

DeLaval is a company that helps farmers produce milk. A cow can only produce milk within a certain interval between being inseminated and the calf growing. For insemination to be successful, the cow must be within a specific window in her cycle, and farmers need to know exactly when a cow is ready.

For this mission, DeLaval wanted to create a product that could identify where in the cycle the cow was, as well as monitor other important health markers.

The solution was smart cows, each fitted with an IoT ear tag that allowed us to measure data points. Our team's task was to collect all the data on the farm, aggregate it, upload it to the cloud (AWS) for cleaning and processing, and then create an interface for farmers to see each cow's position and health.

The entire solution was built on an event-based architecture with serverless technologies such as API Gateway, AWS Lambda, S3, SQS, EventBridge, DynamoDB, and ECS.

Christopher's role as a Cloud Engineer was to handle the initial steps in the cloud process. This included receiving the data, performing extract, transform, and load jobs, and then sending the data to be processed. Additional tasks included setting up CI/CD pipelines in GitLab, deploying with CloudFormation to manage the infrastructure as code, and keeping costs down.

The project was successfully completed with implementation on over 10 farms in Europe and the USA, affecting a total of 40,000 cows. The annual cost per cow was kept to only $1, meeting the client's requirements for both scalability and cost-effectiveness.

Goozo, an education platform with customers in the public sector was looking to move their operations to the AWS cloud. In collaboration with Amazon Web Services, Christopher assumed the role as a Cloud Architect to migrate their existing application to the cloud while complying with Swedish legal requirements as a proof of concept.The solution converted the clients existing application to run on AWS ECS, connect with appropriate load balancers, and AWS RDS. Further, the solution required that each public-sector customer was separated from each other, this forced us to build a multi-tenant solution with each tenant holding their uniquely secured keys.While the final solution enabled Goozo to rapidly establish new tenancies for future customers with minimal code, it faced challenges due to Swedish regulations prohibiting the exposure of public-sector data to foreign states, making the solution unfeasible despite the use of advanced encryption.

Swedish House of Finance hosts a free application hosted on AWS that provides financial data to universities nationwide. Christopher's assignment included documenting the application and suggesting enhancements to lower costs and bolster security. Additionally, he was on standby to troubleshoot and restore the application in the event of any malfunctions.
