Pracovné skúsenosti

2020 - 2023
Java Lead Developer

GoPSG 2 (Komix s.r.o., Czech Republic; Customer: ŠKODA AUTO, a.s) - Cloud micro-service web application

All parts of ŠKODA AUTO ČR vehicles that are replaced under warranty repairs undergo warranty testing, where the cause of damage to the specific part being claimed is analysed as a preliminary part of the process, in which ŠKODA AUTO improves its cars through technical development to ensure that similar defects do not occur in future models. Thus, the analysis mainly needs to cover receiving, releasing, stock operations of the parts and dealing with the dealership that services the order.

The aim was a complete refactoring of the application, with emphasis on UX and UI, to centralize the handling of damaged parts not only in ŠKODA AUTO ČR but also in the foreign markets where ŠKODA AUTO operates. The original application, which consisted of an application running on users' PCs and a web part of the application on the dealership portal, has been replaced with a unified web application running in the cloud environment.


Activities & Responsibilities:

I got involved in the GoPSG 2 project almost at the beginning as a backend developer, when I was tasked to setup the structure of the main service of the application and implementing the first endpoints. Later, my role changed to backend lead developer, where my tasks were to implement the security of the application (SSO SAML, OAuth, x509), integration to ŠKODA modules/systems, reports generation, mail messaging, managing project's code quality as main code reviewer, and maintain build and release management within Azure DevOps. Beside that, I have occasionally participated in minor frontend tasks.
