What we do
From technical direction to hands-on delivery - senior engineers, plain language, no theatre.
-
Technology Consulting
Senior engineers embedded with your team to unblock delivery, shape architecture, and raise the bar on quality and maintainability - so feature velocity stays high as the codebase grows.
-
Custom Software
We design and build software you can evolve safely. Clear architecture, automated quality gates, and delivery practices that keep change cheap for years, not weeks.
-
Workshops & Training
Hands-on sessions in architecture, testing, refactoring, code reviews, Spring, and AI engineering - tailored to your product, your stack, and your real-world code.
-
Studio
From discovery to modernisation: we help products evolve with care, improve UX and reliability, and reduce complexity so future change costs less.
Training
Expert-led training in engineering, architecture, testing, delivery, and AI. Tell us your goals and we’ll build a focused programme your team can apply from day one - on-site in Zürich, on your premises, or fully remote.
-
Workshops for Agile Teams
Level up architecture, testing, code reviews, and more. Interactive sessions tailored to your current product and stack.
-
In-House Trainings
Bespoke programmes in web/backend, cloud delivery, architecture, and testing. Delivered on-site or remote for your team.
Spring Training Courses
Focused, hands-on courses covering the modern Spring ecosystem. Delivered on-site or remotely for your team.
-
Core Spring
Master the fundamentals of the Spring Framework: IoC container, dependency injection, AOP, data access, and Spring MVC.
-
Spring Security
Secure your Spring applications with authentication, authorisation, OAuth2, JWT, and method-level security.
-
Spring Boot Optimizations
Tune startup time, reduce memory footprint, and compile to GraalVM native images for production-grade performance.
-
Spring AI & Embabel
Build intelligent applications with Spring AI and Embabel: LLM integrations, RAG pipelines, and agentic workflows in the Spring ecosystem.
-
Spring Modulith
Design maintainable modular monoliths with Spring Modulith: enforce boundaries, decouple with domain events, and generate living architecture documentation.
How we work
Practical collaboration, modern engineering, and a focus on outcomes you can sustain.
Quality
We invest in testing, observability, and good engineering hygiene to reduce risk and speed up delivery.
Agile & XP
Test-driven development, simple design, pair programming, and continuous integration, practised every day.
Knowledge Exchange
We pair, review, and coach so improvements stick, and your team owns the results.
AI Engineering
We apply AI-assisted workflows, LLM tooling, and agentic patterns where they reduce toil, improve quality, or accelerate delivery.
Let’s talk
Tell us what you’re building and what’s getting in the way. We’ll reply personally within one business day - no bots, no spam, no sales funnel.
Whether you need delivery support, a senior pair of eyes on architecture and testing, or a hands-on training for your team, we’ll point you to the right next step - even if that’s not us.
