The Future of Software Engineering Starts Here

> Rooted in Java. Evolving into the future of software engineering.

JDD 2026 is where experienced developers, JVM engineers, architects and tech leads meet to understand what modern software engineering is becoming - and how to build systems that scale, survive change and make sense in the AI era.

From Java roots to the future of software engineering

JDD has always been strongly connected to Java and the JVM ecosystem. That does not change. What changes is the world around software engineering. Today, developers work with distributed systems, cloud platforms, AI-assisted workflows, security constraints, reliability requirements and long-term architectural decisions. JDD 2026 connects the strong Java foundation with the reality of modern engineering.

> pull_quote

Not just Java.
Not without Java.

ORIGIN_NODE01 / 7

Java / JVM as the origin point

The runtime, ecosystem and engineering culture JDD was built on. Still the gravitational center of everything we do.

REAL_SYSTEMS02 / 7

Real production systems

Talks about software that ships, scales, breaks, recovers and survives change - not slideware.

ARCHITECTURE03 / 7

Architecture and scale

Distributed design, event-driven systems, scalability, resilience and long-term technical decisions.

AI_NO_HYPE04 / 7

AI without hype

AI as an engineering tool: assisted coding, testing, CI/CD, backend integrations and AI-native workflows.

QUALITY05 / 7

Quality and reliability

Observability, testing, performance and the practices that keep production calm at 03:00 AM.

SECURITY06 / 7

Security and resilience

Secure-by-design Java, supply chain, secrets, IAM and compliance built into the engineering loop.

COMMUNITY07 / 7

Community and craftsmanship

Java User Groups, practitioners and engineers from Poland and CEE who care about how software is built.

The JDD Engineering Journey

Five stages of the same software engineering trajectory - not old vs new, but maturity levels of the same craft.

The JDD Engineering Journey schematic
  1. 01
    STAGE_01

    Origin: Java & JVM

    The foundation of JDD. Java, Kotlin, Scala, JVM internals, performance, memory, concurrency and backend engineering.

  2. 02
    STAGE_02

    Expansion: Backend & Architecture

    From writing code to designing systems. Distributed architecture, event-driven systems, scalability, resilience and long-term technical decisions.

  3. 03
    STAGE_03

    Systems: Cloud, DevOps & Platform

    Modern software runs on platforms. Cloud-native backends, CI/CD, observability, Kubernetes, platform teams and operational maturity.

  4. 04
    STAGE_04

    Acceleration: AI-Augmented Engineering

    AI as a practical engineering tool. AI-assisted coding, testing, CI/CD, backend integrations and AI-native development workflows - without hype.

  5. 05
    STAGE_05

    Frontier: Future Software Engineering

    Preparing engineers for what comes next: security, reliability, agent systems, emerging paradigms and technical leadership.

Why join JDD 2026?

REASON_01

For engineers building real systems

Talks focused on production, scalability, maintainability, performance and long-term technical decisions.

REASON_02

Java and JVM remain the foundation

Java, Kotlin, Scala, JVM internals, performance, memory, concurrency, Spring, Quarkus, Micronaut and backend engineering.

REASON_03

AI through an engineer’s lens

No hype. Practical sessions on AI-assisted coding, testing, CI/CD, backend integration and AI-native development workflows.

REASON_04

Architecture, cloud and platform engineering

Distributed systems, event-driven architectures, cloud-native backends, Kubernetes, platform teams and resilience.

REASON_05

Security and quality as engineering properties

Secure Java applications, supply chain, observability, reliability, testing and compliance by design.

REASON_06

Community-driven by design

Meet developers, architects, tech leads, Java User Groups and experienced practitioners from Poland and CEE.
