IT / Web Development × New Graduate

📌 Career Summary

• ▸Served as a long-term backend engineering intern at an IT startup from April 2023 through December 2023. Spearheaded the development of high-performance APIs using Go while concurrently optimizing database query structures to enhance overall system throughput and reduce resource consumption during peak traffic periods.
• ▸Competed in a nationwide student hackathon in August 2022, serving as team lead and primary frontend developer. Directed a focused 48-hour sprint to architect and deploy a fully functional web application, ultimately securing a prestigious corporate award for outstanding user interface design and rapid prototyping execution.
• ▸Since April 2021, have been responsible for developing and maintaining a specialized web scraping tool and data analysis infrastructure within a university research lab. Leveraged natural language processing techniques to automate complex data extraction pipelines, ensuring reliable information flow for ongoing academic publications and experimental validation.

📌 Achievements & Strengths

• ▸Engineered critical API query optimizations and implemented strategic caching mechanisms using Go during my internship phase. This targeted performance tuning successfully reduced average response times from 450 milliseconds down to 120 milliseconds, delivering an approximate 73 percent improvement in overall application responsiveness and user satisfaction.
• ▸Architected and launched a comprehensive matchmaking application leveraging React and Firebase during a competitive hackathon event. The platform achieved remarkable early traction, recording 300 daily active users within its first week post-launch while maintaining a robust 45 percent retention rate among initial adopters.
• ▸Developed a highly efficient Python-based crawler within the research laboratory environment that successfully automated the collection of half a million monthly data records. This automation initiative drastically streamlined our workflow, effectively reducing the research team manual data gathering efforts by approximately 40 hours per month.

📌 Skills

• ▸Frontend Development: Proficient in building responsive and interactive user interfaces using React, TypeScript, Next.js, and Tailwind CSS framework to ensure seamless cross-browser compatibility and modern design implementation across various digital platforms.
• ▸Backend Engineering: Experienced in designing scalable server-side architectures and database management systems utilizing Go, Python, Node.js, and advanced SQL queries through PostgreSQL to handle complex business logic and secure data operations.
• ▸Infrastructure & DevOps Tools: Skilled in containerization and cloud deployment workflows using Docker and AWS services including EC2, S3, and RDS. Additionally, proficient in version control via Git and GitHub, alongside automating testing pipelines with GitHub Actions for continuous integration and deployment.
• ▸Language & Methodologies: Demonstrated English proficiency with a TOEIC score of 860, enabling fluent comprehension of technical documentation and effective daily communication. Well-versed in agile development frameworks, specifically Scrum, to facilitate iterative progress tracking and cross-functional team collaboration.

📌 Self-PR

• ▸Focused on maximizing product value through proactive problem identification and strategic technology selection. During my internship, I identified user churn caused by slow search functionality and independently proposed implementing Elasticsearch. I led the entire initiative from proof of concept to production deployment, ultimately increasing search success rates to 99 percent and eliminating customer support inquiries regarding search failures. I pride myself on writing code that drives tangible business impact while rapidly mastering unfamiliar technologies.
