With Overwhelming Ownership (ATI),

We Think Together, Create Together

ATI's SES is not mere staff augmentation. After deeply understanding client challenges and goals, we assign engineers with optimal skills and experience.

Veteran engineers with rich field experience join as mentors, conducting daily catch-ups and reviews for junior members. We create an environment where the entire team's productivity increases while ensuring reliable delivery.

All engineers are provided with AI development tools like Claude Code, Codex, and Cursor, elevating both development speed and quality through AI collaboration in requirement organization and test design.

We build development systems directly contributing to results by collaborating with field engineers on issue organization, improvement proposals, and operational efficiency. By sharing progress during projects and providing immediate support from both technical and organizational perspectives, we establish 'relationships that enable continuous growth.'

Starting from organizing challenges when scope is ambiguous and building optimal development systems. Even without clear requirements, ATI visualizes the current situation and draws necessary measures together.

Leveraging experience leading multiple high-load services from zero to growth, we proceed with quality standards incorporating test strategies, performance design, and monitoring. We design with stable post-release operations in view.

Rich implementation experience in automation and operational efficiency using AI agents, building development processes considering quality assurance and risk management.

Handling requirement definition, design, implementation, and operations in an integrated manner, flexibly assigning internal and external engineers. Supporting hybrid configurations with SES, pursuing results regardless of scale from short-term improvements to long-term operations.

We design and deliver training programs covering engineering, IT literacy, practical AI skills, and data operations/DX enablement—co-created with ATI practitioners who stay on top of fast-moving trends to keep every session rooted in current field knowledge.

Programs are tailored to your challenges and audience with flexible formats—onsite, online, or hybrid—incorporating the latest technology and DX updates so you can tackle everything from onboarding to reskilling with confidence.

Corporate group trainings and team boot camps are available. Start with a consultation so we can explore the right approach together.
