I am a software engineer with a strong focus on mobile app development, particularly Android development using Jetpack Compose, TypeScript, and blockchain technologies. Recently, I led technical projects for DMM TV, delivering impactful solutions such as optimizing user experience, implementing in-app purchase functionalities, and video analytics. Additionally, I co-founded Leapify Inc., where I developed an automated AI trend report service and took charge of the technical aspects. I have experience developing robust and user-friendly applications using React, Next.js, and AWS, from frontend to backend.

During my master's studies, I majored in technology management and data science, focusing on research in text mining, natural language processing, and machine learning. My master's thesis was titled "Query-Oriented Multi-Document Summarization with a Focus on Causality for Economic Reports," which deepened my understanding of data-driven solution building. Through this research, I gained a solid foundation in machine learning and data analysis.

Currently, at SARAH, I am also working on the development of an L1 chain using Avalanche, contributing to projects that leverage foundational blockchain technology.

Looking for: I am seeking opportunities where I can apply my expertise in mobile and blockchain development, or automation tools, to deliver impactful solutions. I am particularly interested in roles in innovative environments where I can contribute to the fields of AI, blockchain, or mobile app development, especially in technical leadership or development positions.
