Interview tools, written from the hiring side.

I started building software as a teenager and never really stopped.

What began as curiosity turned into obsession. For years the cycle was the same: learn, build, break, fix, repeat, often until 3 or 4 in the morning, not because anyone asked, but because I loved understanding how systems worked beneath the surface.

What started with software grew into something larger. Applications became platforms. Features became systems. Coding became architecture, and architecture became a way of thinking.

I worked across startups, enterprise environments and global technology companies, on products used by millions. But the most valuable lessons rarely came from clean launches. They came from the mistakes, the failed assumptions, the production incidents and the trade-offs that looked perfect on paper and behaved very differently in reality.

Those years taught me one thing above all. Great engineering is not about knowing the most technologies. It is about judgment: making good decisions when the information is incomplete, the requirements keep moving, and there is no perfect answer.

As I grew, I ended up on the other side of the table too: 500+ technical interviews from the hiring side, plus architecture reviews and technical discussions, working alongside engineers at every level. I could see how software gets built, but I could also see how engineers grow.

And I kept noticing the same pattern. Talented people were getting stuck, not for lack of ability, but because nobody had taught them how to connect everything together: mobile, backend, security, infrastructure, reliability, business constraints and trade-offs. Most resources teach technologies in isolation. Real systems do not work that way.

The same study led me somewhere unexpected: communication, visibility and positioning. Skill alone is rarely enough. Whether you are designing software or building a career, people decide based on the signals they can see and understand.

So I started writing it down. First notes, then reviews, then frameworks, articles and books. Altitude came out of that, lessons earned through experience rather than theory. Today, Salari is where I share the rest.

My goal is simple: help engineers think more clearly, design better systems, communicate their ideas, and move faster than I did. Technology changes constantly. The principles rarely do.
