The Hybrid Edge: Business Acumen Meets Deep Technical Execution.
Most technologists write code without understanding the business bottom line, while many business analysts lack the technical depth to understand system constraints. My background bridges this gap entirely.
Starting my career in 2017 as a Junior Database Engineer mapping complex Schlumberger seismic survey data for SKK Migas, I progressed through enterprise database engineering, full-stack backend and mobile architecture, and product UI/UX design. Combined with a formal degree in Business Administration from Universitas Padjadjaran, I help organizations eliminate translation friction between business executives, operational end-users, and software engineering squads.
