Hey! I'm Alex – a Manual QA Engineer with over 6 years of experience in software testing – and more.

This blog is a mix of hands-on advice, reviews, and experiments – all built on real testing experience. Whether you're already in QA or just starting your journey, you'll find something useful here.

I believe that knowledge grows when shared. Let's explore, break, test – and improve – together.

Top Wireshark Filters Every Engineer Should Know


Wireshark remains one of the most trusted tools for network engineers, security teams, and integrators – and its true power comes from display filters that instantly cut through noisy packet captures.

From DHCP and ARP discovery to HTTP inspection and multicast debugging, the article provides practical, ready-to-use filters that engineers rely on every day. Whether you're troubleshooting a camera, analyzing DNS, or tracking HTTPS flows, these filters will dramatically speed up your Wireshark workflow.

Why I'm Starting This Blog


This is the first post on this site. Technically, it's not my first attempt at blogging – but it is the first time I'm using my own lightweight CMS, built over a couple of weekends.

Past attempts didn't last. Time, as usual, was the main obstacle: urgent releases on my work, personal infrastructure troubles, relocations, and business trips – all pulled attention away. So yes, I'm cautiously optimistic this time. Let's see how long it lasts.

But here's the important part: this blog isn't meant to be groundbreaking or revolutionary. Think of it more as a public notebook – an extension of my personal knowledge base. Over the years, I've often found myself explaining seemingly simple, practical solutions to colleagues. Sometimes I'm even surprised: "Wait, you haven't seen this trick before? It's so easy to use!"

That's exactly what I want to share here: the "obvious" tricks, the small scripts, the configuration tweaks, the debugging workflows – things that save real time in day-to-day work but rarely make it into documentation or talks.

No fluff, I hope. No trends-for-the-sake-of-trends. Just working thinks
