Our startup

Two products we build and run ourselves

The same team that ships client projects designs, builds, deploys and supports these products end to end.

Document management · Japan In production

Denshi

Paperwork tracking for Japanese health insurance societies.

Denshi replaces paper ledgers for notification forms — enrolment, loss of eligibility, salary changes and more. Staff register each form with its receipt number, track it from received to sent, attach the scanned files, and find any record in seconds.

  • Status workflow with receipt numbers and Doc IDs
  • Bulk CSV import and batch status updates
  • Upload of scanned forms and attachments
  • Employer registry, audit log and recovery of deleted records
  • Role-based access for admins and staff
  • Runs fully offline on the customer's own server

Martial Arts Booking

Class passes, schedules and student progress for martial-arts academies.

An admin CMS plus a mobile app. Academies sell class passes and token top-ups, schedule group and private lessons for each coach, and keep students motivated with mastery levels and XP. Students book lessons and follow notices and activities from their phone.

  • Class passes: private 1-on-1, small groups, holiday programmes
  • Token wallet with top-up packages
  • Weekly schedule and teaching hours per coach
  • Mastery levels and XP to track progress
  • Bookings, orders and transaction history
  • Notices, activity photos and an Android app for students

About us

A small team that ships

T&D Software is a Hanoi-based team of experienced engineers working with clients in Vietnam and Japan. We take projects from requirements to release, and we stay on for maintenance after launch.

Alongside client work we invest in products of our own. Building and running Denshi and the martial-arts booking platform keeps us close to what our clients go through: real users, real deadlines, real servers.
