From planning to operations, we deliver
tomorrow’s success
with stability & scalability

DJ Family designs and manages the full software lifecycle, prioritizing user experience and trust—from requirements to deployment, monitoring and security.

  • Web & App Development

    • UX research-based IA/design and development of responsive web and hybrid apps
    • Implementation of the latest e-Government framework and frontend technologies

  • Platform Operations

    • Zero-downtime operations using CI/CD, automated deployment and blue/green or rollback strategies
    • Real-time monitoring and performance tuning ensure system stability

  • Integration & Security

    • Integration with external systems, payment/public APIs, and data migration
    • Secure coding, vulnerability checks, and access control ensure system reliability

Architecture

With experience-driven designs, we deliver stable and scalable architecture, continuously optimizing during operations to ensure uninterrupted service.

  • Standards based – e-Government Framework v4.3.0, RESTful API, responsive UI
  • Scalable architecture - modular design for feature expansion, multi-tenancy, multi-region support
  • Operations automation - CI/CD, Infrastructure as Code (IaC), health checks, auto-scaling
  • Data reliability - transaction logs/events, audit tracking

Operations & Monitoring

Service reliability through metrics-driven operations and transparent change management.

  • Real-time monitoring – latency/error rates/traffic, metrics, alerts, dashboards
  • Deployment strategy – phased rollout, blue/green and canary deployments, automatic rollback
  • Performance and cost optimization – cache/query tuning, and automatic resource scaling
  • Transparent changes – tracked via versioning/release notes and event logs

Security & Reliability

Security is a prerequisite, not a feature. We safeguard the service lifecycle with secure coding, vulnerability mitigation, access control and encryption.

  • Transparent operations through role-based access control and audit metrics
  • Encryption and secret management, HTTPS/SSL, firewalls, and WAF implementation
  • Backup, DR, fault isolation and multi-AZ/multi-region configuration

FAQ

QWhat technology stack is used for development?
AWe select and apply the optimal technology stack according to the nature and objectives of each project.
We support a variety of server environments such as e-Government Framework (eGov), Spring Boot, PHP, and Node.js, and we handle databases ranging from legacy systems to modern open-source platforms, including MS-SQL, MariaDB, PostgreSQL, and MySQL.

For applications, we develop native apps with Kotlin (Android) and Swift (iOS), as well as cross-platform apps with React Native.
On the web front-end, we provide both SPA (Single Page Application) development with Vue and React, and traditional MPA (Multi Page Application) approaches.

We also apply responsive and adaptive web design to support various devices. In production, we enhance scalability and security by leveraging proxy servers, API gateways, container-based operations (Kubernetes, Docker), CDNs, and WAFs (Web Application Firewalls).
QHow are deployment and operations carried out?
AWe perform automated build and deployment through a CI/CD pipeline, ensuring zero-downtime operations with blue/green and canary strategies, along with automatic rollback.
QHow is security and data reliability ensured?
AWe implement secure coding, vulnerability assessments, access control, and end-to-end encryption. All major changes are tracked and managed through event logs.
QHow are maintenance and SLA provided?
AWe provide SLAs that include incident response, regular maintenance and performance tuning. Operations are managed transparently through metrics-based reporting and monthly reports.
