Building Scalable SaaS Platforms
and High-Performance APIs
I'm Belic Slavko, a senior Laravel developer with 15+ years of experience. I design and ship backends that power analytics, marketing automation, and subscription products at scale.
From event ingestion and real-time reporting to billing integrations and APIs that stay fast under heavy traffic—I focus on clean architecture, performance, and systems you can grow with.
