- Languages: JavaScript, TypeScript, HTML5, CSS3 (Less/Sass/SCSS), Tailwind CSS, Node.js, NestJS, Java, Java Spring Boot
- Databases: MongoDB, PostgreSQL, Redis
- Other Technologies: Apollo GraphQL, RabbitMQ, Kafka
- DevOps & Tools: Docker, Git/GitHub, Jenkins, Jest (Unit and Integration Tests)
- Cloud Platforms: Google Cloud Platform (GCP), AWS

With my combination of technical know-how and business administration background, I can view projects holistically and implement them efficiently. I have experience in developing scalable, performant web applications and am familiar with implementing responsive designs and user-centered solutions. My knowledge in performance marketing and conversion rate optimization allows me to link technical added value with business goals.

As a communicative team player, I enjoy working in agile environments and value transparent collaboration. I am always curious and ready to learn and apply new technologies. My passion for clean code and modular development drives me to continuously deliver high-quality results.

I look forward to advancing your project with my commitment and expertise.
