Joanna Miler
Summary
I am a senior leader with extensive experience in operations management, team development, and business growth across global blue-chip organizations (Johnson Controls, UPM, Arvato) and fast-growing tech startups (Oyster). With a proven track record of optimizing cash flow, implementing cost reduction strategies, and driving business improvements through modern technologies such as AI and RPA, I am passionate about delivering measurable business outcomes. I am actively expanding my technical expertise in SQL and Python and will begin a Master's degree in Artificial Intelligence and Machine Learning in October 2024. I bring a Lean Six Sigma Black Belt certification and a passion for innovation and continuous learning to lead and inspire teams in fast-paced, high-impact environments.
