Career Journey

Where Business Intelligence Meets Software Engineering

My fascination with technology started in 1994 on a 386. Since then, I evolved from commercial automation, through corporate auditing, to modern engineering. Today, I master AI agents with guardrails, deterministic prompts, and robust architecture. My 20-year holistic vision unlocked a new dimension of productivity.
