Software engineer building web platforms end to end: Laravel backends, Next.js frontends, and the servers they run on. Most of my work is SaaS products, cloud hosting, DDoS protection, and the WHMCS ecosystem.
Anything works on a quiet Tuesday. We build for the bad night — the traffic spike, the failed node, the attack nobody scheduled. That is the only test that counts.
