How I switched from a corporate environment to working in a dynamic, agile company

When I left Microsoft 3 years ago to take on a role in project and events management, my manager that time, Carol Mc Namara, told me that I will be back in human resources soon, because it's what I was born for.

AWS, AZURE or GCP? Huge comparison of cloud providers for the gaming industry

Working in the gaming industry as a game developer, CTO, CEO, game analyst or any other role is challenging. I worked more than 10 years as a Backend Developer and also as a Cloud Team Lead for a gaming studio for the past 3 years and often struggled with my “backend” role.Conversations about the cloud with c-level people were especially challenging. Everyone says they want the cloud but on the other hand they are all afraid of rewriting their games to be cloud-ready. I'm writing this article for those of you who are not afraid. For the forward-thinking ones who are ready to take a step to the cloud but don't know which provider would suit them best. I'm hoping to help you understand all you need to know about the differences between the cloud providers and make the best decision for your business.

Fortunately I could get a bit of Vegas in my living room / home office (and in my heart) with the online edition of re:Invent. It started with Andy Jassy’s (the CEO of AWS) keynote.
