Johan has played an important role in the backend development of an advanced real-time platform atTele2, which is used for analysis and identification of problems in the network. He has specialised instreaming data and the team has built its custom framework in Golang with intensive use of ApacheKafka. With this framework, components were developed and put together in a pipeline thatincrementally processed and managed network data and automatically detected deviations andanomalies, mainly for cable modems (HFC) and fibre networks. During his time at Tele2, Johan hasactively contributed to the design, implementation and maintenance of such advanced components.The work was carried out in a highly qualified R&D team and has often included the streamlining andoptimisation of large data sets using the latest tools and frameworks on the market. Monitoring withPrometheus and Grafana has also been an important area of focus in his work.Technology: Golang, Apache Kafka, Elasticsearch, Docker/DockerEE, Kubernetes, Google Protobuf,Grafana, Kibana, Prometheus, GitLab, Jira.

Development and enhancement of Voddler's product for Peer-to-Peer video distribution. The work included the groundbreaking research and development effort to add support for distribution of Live video using Peer-to-Peer technology.

Support for Closed Captions (Apple HLS) was needed in CastLab's SDK for streaming video playback inmobiles. The assignment was carried out by building a parser of Closed Caption data from H.264streams as well as implementing a decoder to decode the packets and use them in a video player. Thedevelopment was done using C++ and an iOS video player was used for testing and verification.Technology: C++, H.264, Apple HLS, Closed Captions, Git.

Telestream needed an internal company-wide library that enabled uploading of video to cloud-basedservices, such as YouTube, Facebook, Vimeo, Google Drive and Dropbox. After analysing the differentAPI’s and requirements of the cloud services, a generic library was designed and implemented thatworked on both macOS and Windows. The library was written in such a way that all of the company'sproducts could easily integrate with it and utilise the new functionality. The project was carried outusing Scrum. Besides architecture and implementation, Johan was also responsible for automatedtesting of the library.Technology: C++, OAuth2, Curl, CLR, WPF, Win32, WinRT, API, GoogleTest, GoogleMock, Scrum.

Johan contributed to Adtoox’s Java based system for delivering commercials to TV, radio cinemas and web.
