We build systemsthat hold up.

Senior engineers. Real problems. Working solutions.

01 — QA & Test Automation

Quality engineering.
Senior-led. No compromises.

We build test automation systems and lead QA for teams that can't afford to guess. Framework architecture, interim QA leadership, CI/CD quality gates — owned end to end.

Test Automation Strategy

Coverage planning, tool selection, risk-driven prioritization. We assess what you have, define what you need, and build a roadmap that maps to your actual exposure.

Coverage auditRisk mappingRoadmap
Framework Architecture

Playwright, Cypress, pytest — structured for maintainability, parallel execution, and long-term ownership. Page Object Model, fixture strategy, CI-ready from day one.

QA Leadership / Interim Lead

Step in as QA Lead when you need seniority fast. Process setup, team alignment, stakeholder reporting. We own the quality function until your hire is ready.

Interim LeadProcess designTeam mentoring
CI/CD Quality Integration

Quality gates that teams actually respect. We integrate automated checks into your pipeline so broken builds stay broken and the signal is always clean.

API & System-Level Testing

End-to-end coverage across microservices, REST APIs, and distributed backends. We test the contracts between systems — not just the UI layer on top.

Test Infrastructure & Reliability

Flakiness elimination, parallelization, environment strategy. We rebuild pipelines teams have stopped trusting into something that blocks a release for the right reason.

02 — Senior-Led Solution Creation

Full-stack. From architecture
to production.

We build complete systems — not prototypes. Backend, cloud infrastructure, auth, DevOps, and frontend. Delivered by practitioners who've done it before.

Backend Architecture

APIs, microservices, and platform backends that hold up under real load. Designed for longevity — with the failure modes already handled.

Java 21Spring Boot 3PythonNode.js 22
Cloud Infrastructure

Kubernetes, AWS Fargate, CDK, Hetzner. Multi-environment pipelines, self-hosting, object storage. We use what the project actually needs.

Kubernetes · EKSAWS FargateCDK · S3
Auth & Integrations

SSO, OAuth2, SAML, OIDC — enterprise auth done right. Third-party connectors and system integrations that don't create new problems.

SAML · OAuth2OIDCSpring Security
DevOps & Delivery

GitOps-driven continuous delivery. From commit to production, automated and auditable. Teams that need to ship without drama.

GitLab CI/CDGitHub ActionsNexus · K9s
Frontend & Design Systems

Fast, accessible frontends with React and Vue. Strong UX instinct, obsessive about performance and bundle size. Design systems that actually get maintained.

React · Next.jsVue 3 · NuxtTailwind
Mobile & Embedded

Cross-platform mobile apps that feel native. Embedded systems and IoT with Rust. Consumer apps to firmware — full hardware-to-cloud stack.

React NativeiOS · AndroidRust · IoT
03 — AI & Platform Innovation

AI systems that run
in the real world.

Production AI — not demos. Multi-agent pipelines, voice automation, LLM integrations built to be deterministic and reliable at scale.

Multi-Agent Systems

End-to-end AI pipelines with multiple specialized agents. Claude API, AWS Bedrock, coordinated workflows — built to be reliable in production, not just impressive in a notebook.

Claude APIAWS BedrockMulti-Agent
Voice & Automation

Voice input pipelines, Whisper integration, automated workflows triggered by natural language. We build the plumbing that turns AI into something a product can ship.

WhisperPrompt EngineeringSSE
AI-Native Product Development

We build products where AI is a first-class citizen from day one — not bolted on later. Architecture, data flows, and UX designed around what models actually do well.

How we work

Small by design.
Quality by default.

No account managers. No handover layers. The person who scopes the work is accountable for the outcome.

One named lead per engagement

Every project has a lead with full accountability. They set direction, communicate directly, and are responsible for the outcome — not a delivery manager who translates.

Scope first, then execution

We define what done looks like before we start. Clear criteria, no moving goalposts. If something changes, we tell you before it affects delivery.

Vetted expert network

When scale demands it, we bring in specialists we've worked with directly — not sourced from a marketplace. Same standard, regardless of team size.

Get in touch

Let's talk about your project.

15 minutes is enough to know if we can help — and if we can't, we'll tell you who can.

Available for remote engagements — based in Europe, working globally.
