What I'm looking for

I’m looking for AI Training, AI Evaluation, and Data Annotation roles where I can leverage my software engineering background, attention to detail, and ability to follow complex guidelines to help develop high-quality AI systems.

I’m a software engineer driven to support high-quality AI systems. I’m seeking opportunities in AI Training, AI Evaluation, and Data Annotation, where I can apply my technical background and attention to detail to follow complex guidelines accurately.

In my recent experience, I developed and maintained web applications and implemented new features based on business requirements. I collaborate with Japanese team members, work with Git-based workflows (branching, code reviews, version control), and read Japanese technical documentation to support reliable software delivery.

Through my internship, I built a web-based network traffic monitoring tool using Python (Django). I designed a Django interface, integrated EVE-ng and PRTG for data collection and processing, and used Grafana for real-time visualization—then helped deploy the tool to improve network traffic management.

I also strengthen my engineering and AI-minded skill set through hands-on projects, including a graduation thesis that delivered an AI-based browser extension (8.9/10). From backend systems to Android apps and browser extensions, I consistently focus on debugging, problem solving, data validation, and maintainable implementation.
