About Me

Dedicated AI researcher committed to meaningful impact and continuous growth. Inspired by Google’s X lab while studying physics, I transitioned into AI to create real-world change. I co-founded Asleep, developing sleep tech products and gaining hands-on experience across AI modeling, clinical research, and data engineering. Currently at Moloco, I work on large-scale install prediction models for Connected TV advertising, focusing on attribution logic, user modeling, and production-scale ML systems. With a strong foundation in representation learning, domain adaptation, and reinforcement learning, I aim to advance impactful AI through rigorous research and collaboration.


Experience

Moloco Inc.

📆 2024.11 – Present
Machine Learning Engineer (T4)

• Improved install conversion prediction models for Connected TV (CTV) ads by refining attribution logic and model architecture, resulting in improved AUROC and calibration performance.

• Designed user behavior-based features and integrated them into the model training pipeline, improving model expressiveness and addressing data sparsity issues.

• Built a modular data pipeline decoupled from production systems, enabling scalable feature backfilling and improving system reliability.


Asleep Inc.

📆 2020.06 – 2024.08
Cofounder & Director of AI

  • Developed EEG-based AI sleep models in collaboration with Seoul National University Bundang Hospital, achieving state-of-the-art performance.
  • Published research in Nature and Science of Sleep and JMIR Mhealth Uhealth, advancing the company's impact in the sleep tech industry. (Wired Feature)
  • Led clinical studies and integrated AI services with data pipelines from hospitals and consumer apps, automating processes for rapid publication and operational efficiency.

Chief Operating Officer (COO) (2021.11 – 2023.04)

  • Managed HR and internal operations, aligning company growth with organizational principles.
  • Secured compliance with GDPR and CPPA regulations while leading investor relations and business operations.

Lanada Lab, KAIST

📆 2018.03 – 2020.06

  • Led research projects on Multi-agent Reinforcement Learning and IoT networks with partners such as KEPCO and NAVER.
