Honnetenshoku
Japanese workplace review platform enabling job seekers to research companies through employee feedback, salary data, and work-life balance ratings. Built the backend APIs powering the review and analytics systems.
Overview
Honnetenshoku is a Japanese workplace transparency platform where employees share honest reviews about their companies — covering salary data, work-life balance, management quality, and culture. The platform helps job seekers make informed decisions before joining a company. I was responsible for designing and building the backend systems that power the core review, search, and analytics features.
My Role
I joined the project as a backend engineer and took ownership of the API layer from the ground up. This included designing RESTful endpoints consumed by both the web frontend and mobile clients, implementing the review ingestion pipeline, and building the analytics engine that aggregates company-level insights from thousands of individual reviews. I also contributed to the Next.js frontend and handled infrastructure on AWS.
