I'm focusing on modern web development, familiar with front-end technology (especially React, Typescript, Javascript) during the recent work. I was a full stack developer (Ruby on Rails) before. I also have startup experience (working in a lean environment), and  fintech domain knowledge. I'm looking for the job located in Tokyo/Japan.

Work Experience

Feb 2019 - Present (2 years)
Kyoto, Japan

In LINE, I'm in the front-end team which is focusing on fintech projects. We are mostly using React/Typescript.

  • eKYC AI product
    I'm the front-end tech lead in eKYC AI product.
    I design and make the decisions for the app architecture. I'm also doing some arrangement for this product, like coordinating with server-side team, and arrange tasks for my team members, in order to guarantee we can ship the product on time.
  • Bank product
    I worked for Bank product in a short period for project establishing.
    I was working on lots of preparation and technology survey before formal development, such as:
    Investigating security technologies for bank system.
    Building the development environment.
    Creating design system and reusable components with UI/UX designer.
  • Securities product
    Our team was in charge of the one of features.
    One thing I'm proud of is I brought the good culture of writing testing in this product. I built the end-to-end testing guideline and environment with Cypress, Drone, Docker, after that, lots of team members start to write tests until today. It helped us reduce QA's workloads a lot.

Staff Software Engineer

Anfu Solutions

Jan 2017 - Jan 2019 (2 years)
Taipei, Taiwan

Anfu Solutions is a B2B startup company related to real estate market in Taiwan. We provide house price estimation service for bank and government customers. The company is still alive now.

I'm the second developer. Because my employer is a professor from college. His domain is real estate, he didn't know tech stuff very well, so I was more like a consultant at beginning, and then I created whole web service by myself. I was using Ruby on Rails, AWS to build the MVP product. And for some requirements from bank customers,  we also provide Docker image, in order to host our service in bank internally. We were success to obtain 3 bank customers and government's project in early stage, and cooperating with them smoothly.

Software Engineer


Dec 2013 - Aug 2016 (~2.7 years)
Taipei, Taiwan

KerjaDulu is a startup, a recruiting web service in Indonesia market. I joined this company from the beginning to the end. In short, it's a LinkedIn clone in Indonesia, We had 1 million users before, but finally we burned out the capital and the company was dead.

I'm a contract(part-time) Ruby on Rails developer under CTO. 
I tried to find out how to migrate our service from Heroku to AWS, so I was familiar with clouds services (like AWS OpsWorks, ELB, RDS, SES...etc) in this job.
At beginning, we were not really understanding of dividing front-end from back-end architecture, so I tried to refactor some web pages with AngularJS.
I also have the experience to design architecture to send millions market emails/per day and optimize SEO for website.

Engineering Internship


Aug 2013 - Nov 2013 (2 month)

I was assigned to FirefoxOS team (Gaia), built some small features and writing unit tests.
