As a backend developer with about 2 years of experience in the financial domain, I focus on defining and solving systemic challenges rather than just writing functional code.

• Engineering Efficiency: Successfully automated high-volume manual data extraction workflows by implementing Spring Batch, significantly improving operational reliability.
• Productivity & Reusability: Streamlined repetitive financial messaging formats by designing and publishing an open-source library, accelerating overall development velocity.
• Pragmatic Architecture: I believe in keeping systems robust yet simple—bravely stripping away redundant layers or patterns if they no longer serve a practical purpose.
• Continuous Growth: I strive to understand the "why" behind every technology choice. I enjoy diving into unfamiliar technical domains, and sharing my findings through corporate tech talks and personal blog posts to foster growth alongside my peers.

• 💻 Building and maintaining high-integrity internal systems for the financial domain, with a focus on data integrity and operational stability.
• 🤖 Developing custom tools and integrations optimized for AI agents to automate workflows and enhance developer productivity.
