ABOUT ME

I work at the intersection of business performance, leadership, people, governance and AI.

I bring a senior executive perspective to coaching and advisory work, with a practical focus on judgment, capability, execution and measurable business outcomes.

I am deeply grateful to God for every blessing and achievement along my journey, and for the opportunity to use what I have learned in service of others. I remain mindful of my shortcomings and continue to learn and grow with humility.

My AI advisory focus in Indonesia

I help leaders connect business strategy, AI governance and organizational readiness. My perspective combines leadership, human capital and governance with the AWS Certified AI Business Strategist certification. My focus is on AI use decisions, accountability, changes in how people work and implementation planning.

My North Star

Turning Vision into Achievement Through Practical Wisdom.

I use practical wisdom to help turn intention into achievement. For me, vision is not merely an aspiration; it should inform choices, behavior, capability, priorities and execution.

My signature idea

Knowing changes perspective. Knowing how moves the needle.

Knowing can change how we see a situation. Knowing how changes what we can actually do about it. That distinction sits behind much of my work in coaching, leadership, AI adoption, human capital and capability building.

My working philosophy

I am most interested in the point where information becomes judgment, judgment becomes a decision, and a decision becomes sustained behavior and measurable performance.

I therefore combine executive advisory, leadership coaching, business thinking, organizational capability and emerging AI strategy. The disciplines are different, but the leadership question is often the same: what is really happening, what matters most, and what action creates the greatest value with acceptable risk?

My structured coaching conversations draw on the Erickson Coaching Essentials program I completed and are grounded primarily in my Human Capital and executive leadership experience.

ACADEMIC FOUNDATION

Connecting Systems Thinking with Human Capability.

My academic foundation combines Industrial Engineering and Educational Management. This enables me to approach organizational challenges through both organizational systems and human capability—connecting process, productivity and risk with leadership, learning and sustainable performance.

My business lens

I frequently use four lenses—profit, cash, risk and people—to test whether an initiative is creating useful business value rather than activity alone.
