About me

I am a software engineer by heart and I love to code every day – I kind of feel uncomfortable when there is no VS Code or at least a Terminal opened on my screen. I dont stick to a specific language or specific frameworks, but I feel a special love to JavaScript and Python.

Achievements

  • Bachelor in Computer Science
  • Foundet [Company name on request] in 2016

  • Experienced with a lot of languages & technologies like NodeJS, Python, React, React Native, Redux, MobX, Webpack, nginx, Docker
  • Experience in building cloud infrastructure on Amazon Web Services (EC2, Elastic Beanstalk, ECS, CloudFormation, CodePipeline, RDS, Route53) and CI/CD Workflows (Docker, Build Environments, Bitbucket Pipelines, AWS CodeCommit, CodeBuild & CodeDeploy)

Super Strong Skills in

  • Handling data from REST APIs, GraphQL and even XML

Things I am working on to Improve

  • Building super fancy CSS animations (though I can do basic stuff)
