Hyeonsun Jung (Jason) 👋

Interested in building technologies that support human creativity, interaction, and meaningful real-world experiences.

I am a software engineer with 6+ years of professional experience building large-scale financial systems at Samsung SDS and the Korean Federation of Community Credit Cooperoperatives (KFCC).

My engineering experience spans financial platforms, biometric authentication, transaction infrastructure, and software quality, with a focus on building reliable systems under real-world constraints.

Beyond engineering, I have a long-standing background in music. I have played piano since childhood and currently explore music production using Logic Pro and MIDI-based workflows.

These experiences have led me to become increasingly interested in how computing interacts with people — from human-centered systems and Human–AI Interaction to emerging applications in Music Technology.

I am currently preparing for graduate study in Computer Science and Music Technology, with the long-term goal of exploring human-centered and creative applications of computing through research and engineering.

My current interests lie broadly at the intersection of computing, human interaction, and creativity.

• Human–Computer Interaction
• Human–AI Interaction
• Human-Centered AI
• Music Technology
• Human–AI Musical Creativity
• Creative Computing
• Interactive Music Systems

I am particularly interested in how computational systems can augment human capabilities while preserving human agency, judgment, and creativity.

I am currently developing a small research-oriented project investigating how computational audio analysis can support decision-making in music production.

The project uses Python and librosa to analyze spectral characteristics of multitrack audio and investigate potential frequency masking.

Initial Research Question

Can computational spectral analysis help music producers identify potential frequency masking in multitrack mixes?

Music has been a long-standing part of my life alongside engineering.

• Piano
• Music production with Logic Pro
• MIDI-based production
• Band performance and leadership
• Independent music projects
• Preparing my debut single

I am increasingly interested in exploring how my background in software engineering can contribute to new forms of musical creation and interaction.

My work is increasingly centered around one broad question:

How can computing augment human capabilities, interaction, and creativity?

B.E. in Software Engineering — Gachon University (Mar 2012 – Aug 2019)
GPA: 3.84/4.5 (Major: 3.94/4.5)
Completed core coursework in data structures, algorithms, operating systems, databases, and computer networks.

Languages: Java, C, Python, JavaScript, SQL
Security: Mobile OTP, MFA, Biometric Authentication, Cryptographic Workflows
Infrastructure: FEP, Interbank Networks, Core Banking Modules
