Introduction

I’m Janos Miko, a DevOps Engineer and Go developer with more than a decade of experience in cloud infrastructure and automation.

My passion for technology drives me to build scalable, reliable systems that solve real-world problems.

I specialize in cloud-native architectures, infrastructure automation, and building developer-focused tools.

The cloud isn’t just where I work - it’s where I thrive.

Philosophy & Interests

  • Everything as Code advocate: Automating repetitive tasks and treating infrastructure, configuration, and processes as code.
  • Productivity: Leveraging GTD (Getting Things Done) methodology and OKRs (Objectives and Key Results) to manage both professional and personal projects.
  • Philosophy: Applying stoic principles to maintain focus, resilience, and clear thinking.
  • Mental Well-being: I practice daily meditation to maintain clarity and balance.
  • Beyond Coding: Hiking, biking, reading, podcasts, e-books and enjoying life as a dad of two dachshunds and a little boy.

Functional Options in Go
Golang provides a fantastic way of writing functions called Functional Options. This is a design pattern that allows callers to pass a set of options to a function, each represented by a function. Super flexible, and easy to use.
