Trusted by leading AI players and globally recognized companies

From frontier AI labs and leading investment banks to large-scale retail organizations

Top-tier investment banks

Data and AI infrastructure leaders

Global retail organizations

Leading Hospitality platform

There’s a very strong pattern: organisations that already have good engineering environments are the ones benefiting the most from AI. The others struggle.

From human speed to machine speed

Productivity isn’t just about individual output anymore. It comes down to fast feedback, good tools, and environments that don’t get in the way. We help teams build the foundations so moving faster actually leads to better results with AI

Tooling & AI Integrations

Make your engineering environment actually work with AI. We design, implement and maintain:
  • Deep IDE integrations and custom plugins (IntelliJ, Cursor, VS Code)
  • AI-assisted workflows (code review, CI, validation)
  • Bazling fast and scalable Build Systems
  • Custom developer environments
Result: Your teams gain velocity and a step-change in developer experience (DX), while your engineering environment stays stable, scalable, and under control.

Engineering foundations at scale

When code grows (with LLMs it grows quickly!), your system must scale with it. Monorepos & Bazel
  • Designing scalable monorepo architecture
  • Migrating from multi-repo to monorepo
  • Stabilising and optimising Bazel builds
  • Improving DX around build system, educating users
  • Making builds scalable, deterministic and predictable
  • Reducing CI cost and feedback time
Result: A build system that can handle machine-speed code growth. Build system that gatekeeper of quality, not a bottleneck

DX Strategy & Consulting

Before modernising build systems of introducing AI tooling, we help organisations understand how their engineering system works.

We work with platform and engineering leaders to:

Diagnose friction across the development lifecycle

Define a clear developer experience strategy

Align tooling decisions with long-term scalability

Design transformation roadmaps that balance technical and organisational risk

Insights from the field

Ideas, lessons and practical perspectives from our work on developer tooling, build systems and engineering productivity.

Piotr Kukiełka

Principal Engineer at VirtusLab

"If AI tools become a standard part of development workflows, having a single large codebase might make those tools much more effective."

Bartosz Sądel

Engineering Manager at VirtusLab

"Saving even a few minutes in the development workflow - multiplied across hundreds or thousands of engineers - quickly adds up."

Krzysztof Romanowski

Head of Development Productivity at VirtusLab

"If your tests are flaky, your pipelines are slow, and your setup is inconsistent, AI just amplifies the chaos. It doesn't fix it."
