I always try to be active on many Facebook groups, consisting mainly of junior devs (or soon-to-be junior devs). Sharing my knowledge is something that I love to do and despite the fact I haven’t seen everything in the industry yet, I am confident I can help a few people. So, I decided to send my audience a little survey with just one text field for any anonymous question related to programming or IT. I picked the most interesting ones and answered them in this post. Do not take my words for granted though. You can always disagree in the comments and I’d be happy to see your point of view! Read more "Ask Me Anything About IT and Programming Part 1" →

This article provides an intuitive approach to neural networks and their learning process (backpropagation) using some simple undergraduate mathematical formulas and terms. Being a huge believer in value of knowledge sharing, I hope it’ll shed some light for someone starting AI/ML journey or clarify few things for those mindlessly using high-level tools such as Keras (been there, done that).
