New Graduate Engineers Reach Job-Ready Level in 7 Days — TechTrain Conducts Practical Training for New Graduates at DX Platform Companies.

TechTrain (TechBowl Inc., Headquarters: Chiyoda-ku, Tokyo, Representative Director CEO: Masao Ozawa, hereinafter "TechTrain"), which advocates "To be the terminal for all who support technology," conducted a 7-day practical technical training for new graduate engineers at a DX platform company, covering Ruby on Rails, AWS, and Docker.

This training program was designed not just for participants to 'know' technology, but to be able to 'use it in the field,' covering everything from web application development to infrastructure construction and deployment. Participants independently developed business applications using Rails, built development environments with Docker, and configured infrastructure on AWS, reaching a level where they could autonomously manage a series of development and construction processes.

■ Background of the Training — The Deep Gap Between "Knowing" and "Being Usable in the Field"

The challenge with the client company's previous new graduate training was that the content was too focused on basics, leading to a disconnect from actual work after placement.

The mission of this training was to elevate new graduate engineers from merely following Rails tutorials to being able to independently design and explain basic AWS configurations (ECS / ALB / S3, etc.) and Docker environments, making them immediate contributors to their upcoming practical work.

■ Features of the Training

Rails Implementation Curriculum that Gradually Reproduces Real-World Complexity

Beyond simple CRUD operations, participants implemented frequently used real-world features such as search, association, reservation, and authentication in order of difficulty. They experienced the transition from "making something that moves" to "making something with design judgment."

AWS/Docker Course that Articulates "Why this Configuration?"

Participants were guided to understand the logical division of roles for IAM, network, and storage, and to independently assemble production-ready configurations using ECR / ECS / ALB. They also became capable of drawing and explaining configuration diagrams.

Immediate Resolution Mentoring with Combined Offline and Online Support

A system was established where participants could consult active engineers immediately when stuck, using both in-person and chat support. By learning the process of error resolution itself, they developed the self-driving capability needed after placement.

■ Training Results

All participants independently completed business application implementation using Rails.

All participants were able to design and explain production-equivalent configurations using ECR / ECS / ALB / S3.

Eliminated psychological barriers to infrastructure.

Connected to subsequent practical development with "zero lead time."

Participants joined with a common technical stack and design philosophy, allowing them to start without spending time on environment setup or basic syntax confirmation.

■ Future Outlook

In addition to the Rails / AWS / Docker package, TechTrain offers practical training tailored to each company's technology stack, including Laravel, Go, Java, and Python.

All curricula are designed and taught by active engineers at the forefront of the industry, ensuring a training system where new graduate engineers do not struggle with the gap between "training" and "practical work."

We will continue to provide a growth environment that supports both technology and education, emphasizing the experience of gaining practical knowledge from experts, especially in the AI era.

■ Participant Voices from the Training (Excerpts)

"Instead of a 'solution-first explanation → implementation' flow, the training progressed like real-world work with a 'specification → implementation' flow. This allowed me to find solutions to unexpected errors myself, which was very educational."

"It was great to be able to work through the materials while discussing with the team, which helped align the understanding of the whole team and my own. Also, team members and instructors often taught me solutions I hadn't thought of, making it a very valuable 7 days!"

"The environment was easy to ask questions, and the instructor's explanations were very clear. I also enjoyed working with the team."

■ Comment from the Rails Training Instructor to Participants

Mr. Inoue, TechTrain Mentor

"This time, we conducted practical challenges as training. I believe that the ability to understand the background of a given problem, and sometimes even propose changes to specifications, and organize information from perspectives other than just technology to create product features, will be increasingly required in practical work, not just 'making what you're told.'"

"I hope you can apply not only the Ruby on Rails knowledge you gained but also how to communicate when you're stuck and how to deepen your knowledge on the job, in your actual work!"

"This time, the content was about implementing use cases close to real-world scenarios with Rails."
