System Development

SYSTEM DEVELOPMENT

Turning design intent into a stable, production-ready platform.

We faithfully translate design into real environments, handling everything from build and migration to testing and go-live. We place strong emphasis on creating infrastructure that withstands real-world operations, including high availability and disaster recovery.

Cloud Infrastructure Build

AWS / Azure cloud environment design and build. We handle everything from architecture design through implementation, migration support, and go-live.

Infrastructure Build & Migration

From server, network, and storage build to on-premises environment overhaul and migration. We implement solid infrastructure including redundancy, backup, and monitoring.

Web / Application Development

Business applications, web systems, and API development. With 15+ years of web development track record, we have built numerous business systems including sales and HR management.

Groupware Systems

Deployment track record ranging from large enterprises with 30,000 users to mid-sized companies. We build optimal solutions for Office 365, Google Workspace, IBM Lotus Domino, and more.

DATABASE MIGRATION

Core DB Migration Implementation

We have extensive hands-on experience migrating commercial databases to OSS and overhaul accompanying cloud lifts. From SQL compatibility verification and stored procedure porting to data type conversion and performance tuning, we handle every step of migration at the implementation level.

Managed DB Migration

Migration Implementation Scope

  • Schema conversion (tables / views / indexes)
  • Stored procedure & function porting
  • Data type mapping & conversion logic
  • Triggers / sequences / constraint reconstruction

Quality Assurance Process

  • Rehearsal migration in production-equivalent environment
  • Automated data integrity verification
  • Performance comparison testing & benchmarking
  • Rollback plan design & implementation

We have successfully completed numerous core DB migration projects including Oracle → PostgreSQL, MSSQL → PostgreSQL, and DB2 migrations. For cloud lift VM selection and DB instance sizing, we design and implement optimal configurations based on thorough workload analysis.
