I have experience in developing and operating smartphone games, using Go and PHP for server-side development, extracting logs using Python and BigQuery, and deploying to Amazon Web Services (AWS) and Google App Engine (GAE). I have implemented features such as "potential actions" in the game and worked on pre-testing for in-game video distribution to contribute to the successful implementation of important features. In the past, I developed a location visualization and management system (web application) using the Google Maps API on AWS, from requirement-based design to server-side API design, frontend design, system deployment, and technical verification. I have also worked on challenges such as migrating applications from GAE/Go 1st gen to GAE/Go 2nd gen or Cloud Run based on Clean Architecture in my previous job
