Your Success—Our Expertise

Leverage our team of industry leaders—with decades of hands-on product development and turn your digital transformation initiative and software development projects into success.


Identify high-value business objectives as the foundation for actionable strategies. Gain a clear understanding of the strategic landscape while reusing the strengths of  your esteemed heritage systems. Kalele helps you discover, learn, adjust, and execute with a keen strategic focus.

Seek business-driven solutions that propel profit-earning solutions and steer clear of costly technology-driven pitfalls. Kalele serves as your partner in uncovering and capitalizing on innovation opportunities. We guide you in distinguishing between strategic software Capex investments and necessary but undifferentiating supporting systems.

We collaborate with you in achievement-based experimentation and using rapid iterative business modeling. These are some of our strategy-enabling tools:

  • Domain-Driven Design (DDD) Strategic Modeling
  • EventStorming
  • Impact Mapping
  • Wardley Mapping
  • Cynefin Framework
  • Team Topologies
  • Domain Topo Architecture
  • Specification by Example (BDD)
  • User Stories / Job Stories
  • Test-Driven Development (TDD)

Along with our team, apply discovery-based learning to tap into creative thinking and unlock innovative outcomes. We train and work with your entire team—software engineers and business experts alike—to succeed together in discovering maximum business value.


We focus on design, not technology only. We champion simplicity. Our commitment is to balance just the right technology choices with what is more important—your unique business vision. We do this by:

  • practicing DDD strategic and tactical modeling:
    Bounded Contexts, Context Mapping, and Domain Modeling
  • transforming and renewing existing systems
  • applying modern software architecture:
    Ports and Adapters (Hexagonal), Event-Driven, Reactive, Message-Driven, Distributed
  • employing rapid learning, planning, and modeling tools
  • using numerous guiding heuristics

Team or individual coaching sessions permit you to grow under the careful guidance of our industry-leading experts. By taking advantage of our experience, insight, and knowledge, our clients avoid costly pitfalls as they travel the road of digital transformation.



Our expertise goes beyond programming  platforms, languages, and technologies. Sure, we have experience in: Java, Kotlin, and other JVM languages, .NET with C# and F#, Elixir and Erlang, Python, and others. Still, we help you implement:

  • Microservices
  • Modular Monoliths
  • Systems Integration
  • Events-First, Message-Driven, Reactive, and Distributed Systems
  • Scalable, Resilient, Responsive, and Adaptive Software
  • DDD—Domain-Driven Design Solutions
  • DOMA—Domain-Oriented Microservices Architecture
