Case Studies

We solve problems for clients across various industries by leveraging advanced technology and expertise. Here are some of our success stories.

Major Gaming Company Case ​

Background

Our client experienced system downtimes due to unexpected spikes influenced by commercials and social media in their on-premises virtual currency payment system. They consulted us in this situation.

Challenge

The payment system needed to handle high transactions, but improper design and implementation made the system unstable.

Approach

Our team conducted a detailed investigation to identify the cause of the issues. We proposed design and implementation changes to address the identified bottlenecks and built a load testing environment to emulate spikes. Comprehensive load tests were conducted in this environment to ensure a robust system for actual operations.

Result

• Avoided system downtimes
• Improved high transaction processing capability
• Established a stable payment processing environment

B2B SaaS Company Case ​

Background

Our client decided to internalize a consumer-facing project that was being developed offshore and establish a new development team. However, the lack of organized engineer recruitment methods and evaluation processes made team formation difficult. They consulted us in this situation.

Challenge

Due to unorganized recruitment processes, it was difficult to quickly hire suitable personnel.

Approach

First, to support the hiring of a core lead engineer, we organized technical questions and coding tests. As a result, a lead engineer was hired within three months, and a self-sufficient team centered on young engineers was formed through OJT within about six months.

Result

• Rapid hiring of a lead engineer
• Effective implementation of an OJT program
• Formation of a self-sufficient development team

B2B Startup Case ​

Background

Our client adopted a two-week sprint release cycle with Agile Scrum but faced quality issues, with bugs occurring in the production environment with each release. They consulted us in this situation.

Challenge

Frequent production environment failures due to inadequacies in the quality management process.

Approach

As an urgent measure, we streamlined acceptance testing and reviewed the entire development process from downstream to upstream processes. Specifically, we supported the introduction of CI linked to the repository, expanded E2E automated tests to reduce manual effort, and introduced coding standards, linter integration with editors, and automated code review with AI coding agents to improve code quality. We streamlined the review process so reviewers could focus on logic.

Result

• Improvement in quality management processes
• Labor-saving through expanded automated testing
• Improved code quality and stable releases

Non-IT Company Case ​

Background

Our client faced challenges in the centralized management of corporate information scattered across WIKI and Redmine. They consulted us in this situation.

Challenge

Teams struggled to efficiently leverage scattered internal knowledge.

Approach

Our team aggregated existing internal knowledge and built an autonomous (agentic) RAG system. We connected it to internal tools such as WIKI and Redmine in a standardized way via MCP (Model Context Protocol), and ran inference on a local LLM to keep confidential information on-premises. This achieved efficient and secure search and utilization of corporate information.

Result

• Centralized management of internal corporate knowledge
• Improved search efficiency while preventing data from leaving the company
• Enhanced operational efficiency through knowledge utilization
