About

I am a strategic engineering leader with deep experience in driving digital transformation across the software development, supply chain domains and operations. With a strong track record in leading high-impact initiatives, I combine technical expertise with innovative thinking to solve complex business challenges. My approach blends agile product methodologies, data-driven decision-making, and human-centered leadership to build solutions that are not only efficient but also sustainable. I bring extensive knowledge in service-oriented architecture, legacy system modernization, and end-to-end process automation, supported by hands-on proficiency in Java, Oracle, GCP, Azure, SAP, and AI/ML technologies. Over the years, I’ve led cross-functional teams through transformative projects from global supply chain replenishment and automation strategies to the modernization of legacy systems and the introduction of AI/ML-driven forecasting models. These efforts have resulted in measurable cost savings, enhanced operational continuity, and long-term business value. I’m passionate about fostering a culture of innovation, mentoring future leaders, and delivering solutions that push boundaries while aligning with strategic goals.
