Full-stack Developer (Finance & Data-focused)

Hi,
I'm Seohyun Cho.

I build data-driven web applications with a focus on finance and real-world problem solving. I developed an asset management website and a Windows-based USB security system, handling both backend logic and system-level control. I’m currently seeking opportunities in fintech and software engineering where I can combine data, programming, and financial insights.

About

I am a developer with a strong interest in finance, data, and real-world problem solving. I focus on building practical systems, from web applications to system-level tools, and I enjoy working through problems step by step until I fully understand them.

Recently, I have been focusing on backend development, database design, and building secure systems. I also aim to combine my background in applied mathematics and statistics with programming to work in fintech and data-driven environments.

I am looking for opportunities where I can grow as a developer while contributing to meaningful products.
