A decade of building and operating production systems.

Mex Smits
Founder
Mexin was founded by Mex Smits, who started building websites at the age of 10 from his mom's attic room. By 14, he had launched CraftiGames, a Minecraft gaming network that quickly grew into a platform serving hundreds of thousands of players every month. What started as a passion project turned into a full team, real infrastructure challenges, and over a decade of hands-on engineering.
That experience — keeping servers up under pressure, handling massive traffic spikes, building internal tools, managing data pipelines — is the foundation of Mexin. Today, we bring the same battle-tested expertise to client projects. We've built backends for loyalty intelligence platforms indexing 400+ rewards programs across 65+ countries, and we build and operate infrastructure across the full stack.
We don't just build infrastructure. We run it. Our team has been doing this day in, day out, for years. We know what it takes to keep production systems running because we've been doing it with our own platform the whole time.

Built a team of 5+, scaled infrastructure across multiple cloud providers
Mexin: offering the same production-grade expertise to clients
To build and run technology systems that just work, so our clients can focus on their product instead of worrying about infrastructure. Good engineering should make things simpler, not more complicated.
We think about what happens when things go wrong. Monitoring, alerting, and testing under realistic conditions are part of how we build.
We pick tools we know and trust. Technology selection is driven by project requirements, not hype.
We agree on what success looks like upfront and track it through delivery. Clear goals lead to better outcomes.
Building a system is half the work. We invest in monitoring, deployment automation, and documentation so things keep running smoothly.
Our team of 5+ engineers built and currently operates CraftiGames, a real production platform serving 500K+ monthly users. These same people work on client projects. You get engineers who have dealt with real traffic spikes, real incidents, and real production pressure for years, not developers learning on your budget.
We keep things flat and practical. Technical decisions are made by the people doing the work, not by managers reviewing slides.
