Midaxo is a software-as-a-service platform to successfully digitalize processes in corporate development, and mergers and acquisitions. I worked as a full-stack software developer in the engineering team to maintain and improve the platform.

Most recently I was the technical lead for improvements of an integration with a third-party business analysis tool. My main tasks were improving the security of the integration, upgrading and scaling the BI platform both vertically and horizontally, and adding additional data sources.

Before that, I developed a front-end module for synergy tracking in React, worked on improving internal processes and continuous integration pipeline for faster and more reliable deployments, assisted customer support representatives to solve customer issues, and fixed issues highlighted in security audits.

Open Web Portals for Telenor Norway

I was a web developer in a team that maintained and improved public websites for Norway's largest telecom provider.

Noteworthy projects that I developed and improved include a messaging solution on the Facebook App platform to mimic a native Facebook experience and a network coverage map that combines multiple coverage layers with custom map projections and a location search. Besides these features, I also worked on platform-wide initiatives such as a full website redesign and implementation of universal accessibility features. In addition to development, I liaised with an offshore support team and infrastructure providers to solve outages and bugs.

Furthermore, I was the technical lead for maintaining the business-wide web analytics and app analytics solutions that used the Tealium platform to consolidate analytics requirements from various business areas. I maintained and deployed plugins for different analytics platforms. When business requirements changed, I discussed them with stakeholders, planned implementation, tested, and deployed the changes. This ensured successful data collection for more than a million monthly visitors across Telenor's websites and mobile applications.

Scheduling Application for An International Competition

Willem C. Vis International Commercial Arbitration Moot Foundation manages the most prestigious international moot court competition which is held annually in Vienna. At the time, the competition had around 200 participant teams and hundreds of arbitrator judges.

I analyzed business requirements and planned and organized work with a small team of developers to design and develop an internal web application to generate a competition schedule. The main business goals were matching arbitrator time availability with team competition schedules in the group and elimination rounds while complying with arbitrator conflicts of interest and ensuring a full selection of seniority levels on court panels. The application supported importing and exporting MS Excel workbooks to allow batch operations with existing data.

I also assisted the organizers during the three days of the live event to help ensure a smooth technical process with data entry and analysis and to be on call with any unexpected issues with the application.
