Experience
AERQ AERENA
https://www.aerq.com/I participated in the project right from the beginning as a lead developer, and our focus was to synchronize data and content to the in-seat devices as well as to provide an API that can be used to query available data and content. I was involved in a lot of aspects, which included choosing an appropriate technology stack, actually coding the microservices used in the workflow, and creating CI/CD pipelines and tests for those.
BoardConnect Digital Experience Platform
https://www.lhsystems.com/solutions-services/boardconnect-digital-experience-platformAs the team's lead developer, I oversaw the development of a portal application within the platform. I was deeply involved in the low-level implementation details, API interface definitions, the overall general architecture of the portal application itself, and adherent processes that helped transfer content from the ground to the aircraft.
SignTechForms
https://www.signtechforms.com/I started as a web developer and my responsibility spanned the whole web part of the platform. I was involved in the development of the API that was used both by the mobile applications and the web UI, the web UI, and the platform website itself.
