“We will work as a group, we need to be a real team, that is the only way to go far” (Francesco Totti)

Sometimes I feel sorry for our recruitment team. They spent years looking for rockstar developers, only to realize that the developers they should have been searching for are actually ninjas. When they finally found where ninja developers live, and learned to speak the ninja language, the target moved once again. Right now, the thing they need to hunt is called a 10x engineer. But what exactly is a 10x engineer? How do you identify one?

Looking from the other direction, as a software engineer, if so many employers are looking for 10x engineers and some are willing to pay them 5x or even more, it’s only natural that I would do my best to become one. …

“To the Power Plant Run-Off Stream, please, I need to collect a Three-Eyed Fish for my Science Class” (Lisa Simpson)

Metaphors are great. Especially when we as developers need to explain our geeky world to people who don’t write code.

Technical Debt is a metaphor, coined by Ward Cunningham, co-author of the agile software development manifesto, as well as a guru in the fields of object-oriented programming and design patterns. In this video, he explains the tech debt metaphor:

The explanation I gave to my boss, and this was financial software, was a financial analogy I called “the debt metaphor”. And that said that if we failed to make our program align with what we then understood to be the proper way to think about our financial objects, then we were gonna continually stumble over that disagreement and that would slow us down which was like paying interest on a loan. …

If you have ever built a B2B SaaS product, I am betting that one of the first things you were told is that multi-tenancy must be the operating model for your entire product.

Marc Benioff, founder & CEO of the most successful SaaS company in the world, said (2008):

“Multi tenancy is a requirement for a SaaS vendor to be successful”

It’s not a threat, it’s a promise

I want to tell you a story about building SaaS products and growing fruits in your garden. I find that the two things have a lot in common.

Around the same time that my team was working on a SaaS B2B product at work, my family and I were building our new house. We had a dream of growing fruits. Nothing huge, ~10 trees, mostly for the colors, the smells, and a fresh bite here and there. ״The kids will take care of the trees״, she said. …

Things to consider when optimizing your org structure

“Nothing we can’t fix in a day or two” (source:

You probably noticed that every presentation or article about agile software development or about micro services architecture can’t be considered scientific nor serious unless it somehow mentions Conway’s law.

Back in 1967, when “full stack” was still describing a state of a data structure and if someone told you that he is “moving to the cloud” you sadly asked him what kind of terminal illness are you suffering from?, Dr. Melvin E. Conway wrote:

“Any organization that designs a system will produce a design whose structure is a copy of the organization’s communication structure”

This makes perfect sense. The canonical example in a good presentation about Conway’s law would be an org which is divided into 4 R&D groups and is assigned to the task of implementing a 3 pass compiler, and somehow ending up building a 4 pass compiler. …
