01 — About
I am a manager and developer specializing in the intersection of scalable software architecture and modern AI. I advocate for a hybrid approach: leveraging the power of public AI for general productivity while implementing local LLM infrastructure for sensitive data and core business logic.
Currently, I combine my leadership experience as Head of Development with a deep technical focus on private AI infrastructure, ensuring that AI-driven workflows are high-performance, cost-efficient, and compliant with strict data privacy standards.
