We're excited to share that Mateusz Wos is joining Resend's Trust and Safety team.

Mateusz brings experience across infrastructure, experience management, and e-commerce where he got hands-on with email systems in a variety of real-world contexts. He's also built his own CRM startup, adding a strong product and customer perspective to his background.

That mix of enterprise scale, practical product work, and founder mindset makes him a great addition as we continue raising the bar on trust and safety at Resend.

How did you get into software?

I’ve been super into tech since I was a kid. I actually destroyed my parents' TV once when I was 7-8 years old trying to figure out how it worked. They weren't exactly thrilled, but it definitely sparked a lifelong curiosity.

A few years later, my older cousin started studying Computer Science, and since he was my absolute idol, I immediately wanted to copy him. I begged my mom for a copy of Pasja C++ (a total classic in Poland), and once I opened that book, there was no going back. From that moment on, I was completely hooked on programming.

What does your desktop/home screen look like?

Why are you at Resend?

I absolutely love working on products I’d actually want to use myself. Being your own target user makes it so much easier to catch those make-or-break details, whether that’s smoothing out a clunky setup or that awesome moment when a tool just "clicks".

Honestly, in my past roles, I spent way too much time wrestling with other email providers, and I deeply hated dealing with nightmare onboarding, random blocklisting, and waiting two weeks for support to finally reply. I'm here because I want to fix that exact problem for other devs. Building a tool that I’d personally choose for my own stack pushes me to care about the actual developer experience, not just shipping code that technically works.

Where do you find #inspiration?

It might be a bit cliché, but I find the most inspiration in the people around me.

We all have so much in common, but it's those tiny, unique quirks that really make me step back and rethink my own worldview. Whether it’s getting a glimpse into someone's niche passions, weird daily rituals, or just a totally different perspective, connecting with others is always what sparks new ideas for me.

If you weren't programming, what would you be doing?

I’ve always daydreamed about opening a small restaurant. I'm probably romanticizing it way too much, as cooking for friends or myself is definitely a lot easier than running a full-blown kitchen. However, I just genuinely love cooking and sharing great food with people, so it's a really fun dream to hold on to.

Favorite tool?

Right now, it would be Raycast. I honestly didn't realize just how much I rely on it until I had to set up a new laptop recently.

Favorite hotkey?

Sticking with the Raycast theme, it definitely has to be ⌘ + Space. Since I replaced Mac's default Spotlight with Raycast, I probably hit that shortcut well over a hundred times a day. It's just pure muscle memory at this point :D

Favorite place to visit?

Probably my hometown - mostly because my family and best friend still live there.

Krakow (where I live now) is definitely more beautiful and packed with way more things to do, but for me, a great trip is always more about the people you're with than the place itself.

If I had to pick a close second, though, it would absolutely be Thailand! You just can't beat the incredible street food, the stunning sights, and of course, the super friendly people.

Advice for ambitious software engineers?

Don't just learn how to use a framework or tool, take the time to understand how it works under the hood.

If you really want to level up as a software engineer, dig in and figure out how they actually work under the hood. When you know the 'why' behind the code, you stop blindly following tutorials and start designing things from the ground up.

Plus, it teaches you how to efficiently debug, helps you pick up new tech faster, and makes you a much more capable and independent developer overall
