I’ve been fortunate to work with many talented people throughout my career. Together, we turned countless ideas and challenges into something tangible— those shared moments of creation remain my greatest source of pride. I began my career as an engineer and have since thrown myself into development, operations, sales, planning, and marketing— spending the past two decades learning every part of how things are built and how they reach people. Over the last ten years, I’ve focused mainly on marketing and data analytics, working across a wide range of business models—from early-stage startups to large enterprises. I’ve had the privilege of being part of projects that shaped new businesses from the ground up (0→1) and helped existing ones grow from 1→10.More recently, I’ve been exploring AI-related work, including data annotation and voice recording projects (Voice Acting / Audio QA), expanding into the field of AI training data. Regardless of title or employment type, I try to keep asking myself one question: what can I contribute to make the world move forward, even a little?That question continues to guide how I learn, create, and grow each day.…I’ve been fortunate to work with many talented people throughout my career.
