  Tadoku

  2019 — present

  Tadoku is a friendly foreign-language immersion contest and tracking platform aimed at building a habit of reading and listening in your non-native languages.

  A minimal viable product was tested in 2019 and the website officially launched in 2020. About 100 people participate per official contest, a number which is steadily growing.

  On the frontend we have a collection of TypeScript Next.js apps using TailwindCSS, React Query, zod, React Hook form, chart.js, and more. There's also a design system.

  The backend services are written in Golang and built through Bazel. The data is stored in a PostgreSQL database. It's deployed to a Kubernetes cluster on Linode via Argo CD.

  User management is handled by Ory Kratos and requests are authorized by Ory Oathkeeper.

  Local development environment is built with Tilt, a tool to run a local development environment in Kubernetes.

  Wantedly Visit iOS

  2018

  Wantedly is a technology company which offers a social recruiting and employer branding platform.

  In 2018 they wanted to revamp their iOS app in order to increase the monthly active users. I was part of the team that built the new Visit app.

  My main contributions were towards the onboarding flow, LinkedIn & Facebook authentication, and the profile screen.

  The revamp was well received and lead to a significant increase in people applying to jobs.

  Wantedly Visit

  2016-2018

  Wantedly is a technology company which offers a social recruiting and employer branding platform.

  I was the first engineer on the international expansion product team. I was responsible for the growth of the product in Singapore, Indonesia, Hong Kong, and Germany.

  I built a variety of features to support our international growth such as an email template manager for marketers in local markets, online payments in Singapore with Stripe, a new onboarding flow, and more. A chunk of my time was spent analyzing user behavior. Those results were then used to figure out what to focus on next.

  Wantedly Visit is originally built as a monolithic Ruby on Rails application. During my time there we slowly migrated to a microservice architecture running on Kubernetes.
