    System Development

    Scalable, secure and future-proof digital solutions

    Good system development is not just about writing code. It's about creating digital products that are sustainable, scalable, secure and easy to further develop over time. In a world where the pace of change is increasing and requirements for security and regulatory compliance are tightening, organizations need to develop systems that not only solve today's needs – but work and evolve tomorrow as well.

    At Agency 42, we build systems with a holistic view. We develop software that is technically modern, business-oriented and built in a way that fits into modern delivery flows. System development is closely linked to DevOps and DevSecOps – and for us, it's a natural part of the way we work.DevOps och DevSecOps

    System development that connects with DevOps and DevSecOps

    Traditional development where code is handed over to operations without context or process often creates bottlenecks, errors and inefficiency. We instead work with a flow where development, automation, quality, operations and security belong together.

    Our philosophy:

    • Build right from the start
    • Automate everything possible
    • Security should be integrated, not bolted on
    • Systems should be further developed without being torn apart

    This is system development created for modern DevOps and DevSecOps environments.

    We help you build systems that last

    Technically, organizationally and business-wise.

    1. Modern backend and frontend development

    We develop systems and products with modern frameworks and technologies:

    TypeScript / JavaScript.NETPythonGoNode.jsReact / Vue / Next.js

    This gives you solutions that are fast, robust and easy to scale.

    2. Architecture and technical design

    Good systems start with good architecture. We help you create:

    • Microservices or well-structured monoliths
    • Event-based systems
    • API-driven architecture
    • Secure integration patterns
    • Cloud architecture (Azure, AWS, GCP)
    • Kubernetes-first eller serverless-modeller

    Architecture is always connected to DevOps processes, security requirements and future growth.

    3. Testing, quality and automation

    This is where system development and DevOps really meet. We build:

    • Automated tests (unit, integration, E2E)
    • Quality controls in pipelines
    • Static analysis and container scanning
    • Security tests (DevSecOps)
    • Version control and review processes

    This gives you more stable releases and reduces the risk of errors in production.

    4. Integrations and system connections

    Most modern systems don't live alone. We help you with:

    • API design
    • Integration layers
    • Secure connections between internal and external systems
    • Real-time data, message queues and event flows

    Everything with focus on security, traceability and future development.

    5. Production-ready systems – built for cloud, containers and Kubernetes

    The systems we develop are always built for modern operations:

    • Cloud-native architecture
    • Containers as standard
    • Kubernetes-anpassade applikationer
    • Logging, metrics and observability from day one
    • CI/CD-ready project structure

    This means the system is ready to run in DevOps flows without friction.

    6. Secure systems – from code to production

    Security is an integrated part of our development process, not an afterthought:

    • Secure coding principles
    • OWASP Best Practices
    • SAST/DAST analysis
    • Package scanning and secrets management
    • SBOM and third-party overview

    This makes the system ready for future requirements such as NIS2, CRA and industrial security standards.

    The result: A software product that works – and continues to work

    When we develop systems, you get:

    Faster time-to-market
    Stable and secure architecture
    Good performance and scalability
    Clean and modern codebase
    Automation that reduces risks and costs
    A product that works as well in production as in development
    A codebase that can be built on without technical debt

    This is system development that is modern, sustainable and future-proof.
