ABOUT MARTIN MAZEIN
I\'m Martin - Staff Software Engineer at Checkly, helping engineering teams catch production issues before their users do, powered by monitoring as code.I\'ve been building software across the entire stack for over 15 years: Linux kernel and virtualization at Amazon EC2, production database infrastructure at scale at Meta, and mobile apps built from scratch and shipped to the App Store and Play Store. Whether it\'s a failing cloud function or a misbehaving network layer, I\'ll find the problem.I embrace AI-driven development as a force multiplier, but I\'m an engineer first. I write code, I read code, and when things break, I debug them across every layer from network to application. AI makes me faster; deep technical understanding is what makes me effective.Beyond the code, I care about the people and the process. I mentor engineers, advocate for the right customer solutions even when it\'s uncomfortable, and stay calm when things get urgent. I believe great engineering is as much about clear communication and cross-functional alignment as it is about technical skill.
