Business vs Technology Founders: Why Balance is Key
From life experience in general I grow more & more to believe that balance is key. Similarly when it comes to software development a proper balance of business vs technology founders is important. I’d say it’s among the most critical indicators of whether the whole enterprise will be successful or will get derailed eventually. Let’s…
Node.js: is frontend or backend?
I’ve recently noticed a bit of popularity of the question from the subject – “Node.js: is frontend or backend?”. That made me think about what is obvious for someone may be not that obvious for someone else. The question is probably coming from people beginning their journey in computer science (CS) space. And most of…
Micro frontend: what & why
Micro frontend architecture approach is the answer to challenges which in their nature are similar to what microservices architecture solves on the backend. I covered microservice implementation principles and decision framework on choosing such approach previously. Let’s cover what this approach is all about.

Why do we use Node.js in our backend?
Ryan Dahl kicked off work on Node.js in 2009 on top of two years of research related to server-side web components. The journey of the runtime wasn’t a smooth ride at all but as of today the major component of its semantic versioning hit 18. The revolutionary premise of Node.js was “server-side JavaScript” because since…
Backend for Frontend – What is it?
Backend for Frontend design pattern – BFF for short while it’s definitely not “Best Friends Forever” 🙂 – seems to get some hype lately. It’s nowhere a new thing: one of the first mentions were by SoundCloud guys back in 2015. Basically it’s a specialized case of a more generic API Gateway pattern. Let’s figure…
503 Backend Fetch Failed – WTF?
At high level “503 backend fetch failed” boils down to an HTTP protocol status code from the 5xx group. 5xx group consists of so called “server errors” which means that client’s request overall seem to be valid but server failed to fulfill it. Some common reasons for such behavior include: Some bug in the application…
Why is there a big pay discrepancy between different software engineers?
From a client’s perspective it may be confusing to pick up an independent developer. That’s because prices for what seems to be similar work may be drastically different. For instance, it’s not uncommon for web development work to be priced in $20-200/hr range. How so? Why is there a big pay discrepancy between different software…
