Hi, I'm a Business Analyst at Delivery Hero (Woowa).

I specialize in analyzing rider and delivery data, improving customer service quality, and driving business decisions through data.

I'm passionate about automating workflows and building efficient systems that save time and scale effortlessly.

I enjoy learning new tools and technologies, and I'm currently diving deeper into Java backend development to enhance my technical versatility.

From scripting dashboards to designing data pipelines, I love solving complex problems with elegant solutions. 💡

While I typically use PowerShell in the terminal, I personally prefer Bash or zsh.

For web development, I work with Java and Spring, using IntelliJ as my development tool.

For data analysis with AI, I prefer Python, leveraging TensorFlow for machine learning, and Selenium for data collection.

When I need to visualize data or create lightweight sites, I turn to Flask.

I primarily work with Presto (Trino) for large-scale data analysis, and utilize Apache Hive with Zeppelin for exploratory querying and reporting.

For real-time monitoring and metrics collection, I rely on Prometheus, which integrates well with my workflow for time-series analysis and alerting.

For personal projects or lightweight use cases, I opt for PostgreSQL or SQLite due to their simplicity and ease of setup.

I’m most comfortable working in Linux-based environments, which makes macOS my preferred platform for development.

That said, I’m also proficient with Windows, especially when aligning with corporate or localized development environments.

For day-to-day work, I primarily use Python, so VS Code is my go-to editor.

When working with Java or managing complex data workflows, I turn to IntelliJ IDEA or DataGrip for a more robust development experience.

For team collaboration, I mainly used Jira and Slack.
To track user reactions and for marketing purposes, I worked with Braze for app push notifications.
