    Discovery & Planning

    We translate your business goals into technical requirements. Scope, risk and technology choices are clearly documented.

    Development

    Short iterations on a trunk-based flow; code review, type safety and static analysis are the default.

  4. 4

    Testing & QA

    Unit, integration and end-to-end tests run automatically before every deploy, alongside performance and security testing.

CASE STUDIES

Measurable results for our clients

We treat every project like a product — from initial goals to production metrics.

SAAS • B2B

AI-assisted CRM for a sales team

PROBLEM
Manual lead scoring slowed the team down and opportunities slipped through.
APPROACH
We added a RAG-based AI layer to a custom CRM: automatic scoring and next-best-action suggestions.
RESULT
Lead conversion up by a third; first-response time cut by more than half.

CMS • MEDIA

Multi-brand headless CMS platform

PROBLEM
Five brands ran on five separate WordPress installs; publishing took days.
APPROACH
One headless CMS with a locale/brand schema and a multi-channel delivery API.
RESULT
Publishing time reduced by two-thirds; infrastructure costs cut almost in half.

DEVOPS • FINANCE

Zero-downtime deployment & observability

PROBLEM
Monolithic services, weekly maintenance windows and no visibility into production.
APPROACH
Microservice extraction, blue/green deployments on Kubernetes, end-to-end tracing with OpenTelemetry.
RESULT
From one deploy a week to many per day; mean time to recovery down from hours to minutes.
