Project Overview

Stationed at a major telecommunications company, I was responsible for the development and maintenance of a content management web application system for robots, a service developed by our customer for their corporate users (i.g. retail industry, retail food and beverage, etc). As the leader of about a 6-member team, I've been responsible for a wide range of tasks from client negotiation, design, implementation, and man-hour/progress management. In development, I mainly worked on the front-end side, but also handled the back-end, DB, server, and CI/CD. The system has a rich workflow-type UI to enable to create robot contents easily, and features complex event and data management in addition to the ability to preview robot behavior. 【Reference Link】

Project Overview

I was responsible for the design, development, and maintenance of a WebRTC video calling application for help desk users (operator). This system is remake as a web application from iOS application developed in France. I was involved in this project from the first release and was mainly responsible for the implementation of the call screen where the operator talks to robot. At first release, this system has a problem that it takes too much time about 15 seconds to start calling. We have re-examined the way in which we set up the call connection and have succeeded in reducing the time taken to initiate the call to around 8 seconds. 【Reference Link】

Project Overview

I participated in a robot-facility staff-resident management project with my client for a care center in collaboration with a national research and development agency. I was involved in both front-end and back-end development of a web application in a management system within this project. On the front-end side, I was responsible for the design and coding of features for managing photo information for facial recognition of a resident and conversational content according to resident's profile information. On the back-end side, I was responsible for the design and coding of APIs for registering resident information and a function for converting CSV uploaded conversation contents into JSON format and uploading them to AWS S3.

Service Overview

As a personally developed application, I created a positioning map tool. The application is created as a PWA so that it can be used like a mobile application. The authentication part is used Firebase Authentication SSO, and the backend API is implemented as a modern flexible interface using GraphQL. In the future, I would like to add various types of analysis and make it an analysis service that users can freely use. At present, It has only partially completed the part of feature, but in the future, we would like to add various types of analysis as an analysis platform to make it an analysis service that users can freely use. Eventually, we would like to create an analysis platform that can be used by friends to exchange opinions on the visualized map, and by research companies to conduct market research.

Service Overview

I've created a line official account as an application that will help me manage my stock holdings. The backend API created in Express (Node.js) parses the Line messages and accesses the spreadsheet data via the GAS API when stock information is needed. The spreadsheet manages the current situation based on the stock information collected by scraping from many websites and the inputs in it. Additionally, every day at the time when the stock market closes, a job is executed and today's stock results are notified as a daily report. In the future, I would like to implement functions such as linking not only to spreadsheet information but also to social networking services such as Twitter, analyzing trends through machine learning, and notifying users.

Service Overview

I've created an RPA web application that automates the process of registering on a daily basis. The RPA tool was created as a WebApplication because it can be run from any environment without depending on the device, and it can also be used by other members. To run the browser automation on a PaaS environment like Heroku, I use the Puppeteer library with built-in driver and Chromium. Furthermore, I've extended the application to be containerized so that it can be deployed independently of the environment. This application is triggered by an API request created in Koa.js (Node.js), which launches a headless browser and executes the daily registration process on the back-end. The execution result is saved as a capture and displayed on the front side.
