Root Access to Innovation: 14+ Orbits in the Dev Universe

I've spent over 14 years navigating the software lifecycle — from the early days of mobile development to architecting multi-cluster, AI-driven ecosystems. I've worn many hats: QA specialist, Full-Stack Engineer, and CTO. If the tech stack were the Matrix, I've moved past just dodging bullets; now, I'm the one designing the simulation.

The "Why" Behind the Code

I don't just ship features; I build solutions that move the needle. Whether it's reducing B2B lead processing from days to under 4 hours via automation or building real-time conversational AI agents in Slovenian, I focus on high-availability and extreme efficiency.

The Technical Arsenal

  • Back-end Sovereignty: Python, Golang, and Java.
  • AI & Data: Weaviate, RAG pipelines, LangChain, and custom TTS models.
  • Full-Stack Versatility: Vue.js, Angular, and Flutter for mobile.
  • Infrastructure: Docker, Kubernetes, and Cloud architecture (Azure, Google Cloud).

When I'm not optimizing PostgreSQL databases or managing side-projects, I'm usually out of range of the nearest cell tower. I measure my downtime in mountain peaks and miles run, usually with a Hans Zimmer score playing in my head to make the uphill climb feel like an Interstellar mission.
