Description / Reflection

I'm a curious and open-minded person. Through these traits, I also wear the devil's advocate hat - both in the business environment and private matters. By that, I mean, that I try to entertain the idea of - " why can't this be this way, why are you dismissing this?". The "5 whys" technique is beneficial when exploring these paths. Of course, especially in technical discussions, the "why's" need to be backed by knowledge and experience.

I approach the work that I do for companies with intrapreneurship spirit. Being technical from the roots sometimes still leads me to do the later in this quotation - "it's better done than perfect.".

Leadership, productivity and self-growth are other topics that interest me a lot. The trigger to study these topics more in-depth came after my first child was born, I think many parents face this - "How do I make and leave the world a better place?", "how do I teach my child ?". The answer is simple - not through words, but through practice, trough your actions and the example you show, by how you carry yourself. Be the example.

Software Engineering is hard. I feel that currently, it is overhyped by big software companies. It is a higher salary occupation and "good" providing one. If you are into it, it is excellent news. Still, people need to understand that the computer field evolves very fast. The learning in this line of work needs to be constant, and you need to be on top of it, if not ahead. You must have intrinsic motivation.

So to mention my current tech buzzwords:

  • Typescript/Javascript

    • Node.js
    • React & React Native
    • Vue
  • Go'lang
  • GraphQL, REST
  • Docker, Kubernetes, Serverless
  • Automated workflows, CI/CD
  • PostgreSQL, MongoDB, Firestore (by firebase)
  • Google BigQuery, Google Data Studio
  • Agile: Scrum, Kanban
