Curriculum Vitae
I have always been passionate about computer science and enjoy exploring new technologies, especially in full-stack web development. My work involves containerization with Docker, orchestrating Kubernetes clusters, and deploying applications in cloud-native environments. I build backend systems using frameworks like Spring (Java) and Express (Node.js), and develop frontend applications ranging from static HTML pages to fully dynamic single-page applications (SPAs) using modern JavaScript frameworks such as Vue or React. Since 2018, I have been working professionally as a software developer. Below is an overview of my technical experience and skill set.
Work Experience
Software Developer and Product Owner
at Ceyoniq Technology GmbH since January 2020 (Software Developer), since June 2023 (Product Owner)
Responsible for the development of an interpreter for a “WYSIWYG” layout designer. The interpreter dynamically assembles a web interface from the ECM system’s data.
Core Work Areas:
- Development of a REST API in Java to collect data from the ECM system, enabling the user interface to be populated with accurate data.
- Interpretation of data in the frontend using the Vue.js framework with TypeScript.
- Creation of a script API (TypeScript/JavaScript) for advanced users to add specific business logic not available in the standard ECM system.
- Unit testing with Vitest/Jest, integration, and e2e testing with Playwright.
- Development of a web component library using the Lit web component framework.
- Leading and organizing a cross-functional team.
- Ensuring alignment between sprint tasks and the strategic objectives of the company.
- Defining and prioritizing product features.
- Maintaining a well-groomed product backlog (using Jira).
- Fostering effective communication between team members and stakeholders.
Additional Responsibilities:
- Introduced TypeScript, (JavaScript/TypeScript) unit testing, and e2e testing with Playwright company-wide at Ceyoniq.
- Promoted to Product Owner due to dedication and strategic vision.
- Also responsible as Lead Developer for the team.
