I’m a passionate Systems Engineer with strong experience in Cloud technologies. Over the last 5 years I have led to completion many projects involving Cloud infrastructure, developer tooling and security. Having had ownership of all aspects of a SAAS production’s infrastructure I have acquired a broad set of intersecting knowledge. Iā€™m constantly looking to learn from my peers and grow by tackling new problems and getting out of my comfort zone. More info about my work experience is in my resume.

Projects I have worked on have given me the opportunity to refine a set of guiding principles which help me in my work. Some of these principles include:

  • Everything as code
  • Ownership
  • least privilege
  • Knowledge sharing
  • Build for the long term

I have also developed a methodology which helps me to proceed in a systematic way through the stages of a project. The broad steps are:

  • An initial document that lays out the who, why and how. “Why” this is something that is worth spending time on. This is should always be understood as “how is this going to add value”. “Who” will be involved in the project and “how” will the identified “problem” will be solved.
  • Proceed to decompose the project into sub-problems with clearly defined timeline.
  • Involve all stakeholders and communicate on what are the changes that are going to happen and what is expected from everyone.
  • Work on the tasks

Throughout the duration of a project. My core values will be my mental framework that will help me make progress and ensure that all decisions taken are consistent with previous work and the company’s values.


Here is a selection of words that are part of my daily vocabulary.
