Rayhan Nento
A proactive and results-oriented professional with extensive experience in operational management, data analysis, and technical implementation. With over three years at PT Telkom Akses, I successfully optimized inventory processes, achieving 100% data accuracy through spreadsheet-based validation and maintaining a 0% material damage rate for three consecutive years. I have a proven track record of leading technical projects, including designing and implementing an automated workflow system that significantly reduced manual administration. I also developed a real-time inventory dashboard using Google Looker Studio to support data-driven decision-making. I am committed to leveraging this blend of operational, analytical, and leadership skills to drive process efficiency and support a company's strategic goals.
