Over 20 years of experience across energy, finance, automotive, healthcare, retail and logistics — from requirements analysis to secure production operations.
01 — Interfaces & Integration
▾
Connecting, converting and operating interfaces between diverse systems and formats — from SAP through Azure to custom APIs. Specialised in EDI/EAI and B2B/A2A integration.
02 — Process Automation
▾
Automating business processes — with RPA, AI agents or custom-built software tailored precisely to the requirements of your operations. Recurring workflows run reliably and without manual intermediate steps.
03 — Software & Solution Architecture
▾
From requirements analysis through concept and proof of concept to a robust architecture. Also as accompanying architecture review and translation between business and technology.
04 — Custom Software Development
▾
Full-stack development of custom applications, web apps and mobile apps — including tests, documentation and UI/UX. The right technology instead of an off-the-shelf solution.
05 — Migration & Modernisation
▾
Modernise legacy systems: update frameworks and versions, close security gaps and migrate systems with zero downtime — with measurable performance gains.
06 — DevOps, Cloud & Infrastructure
▾
Building highly available, containerised environments with automated deployment, backup and monitoring — on-premise or in the cloud on AWS, Azure and GCP.
07 — IT Security & Secure Communication
▾
Identify and close vulnerabilities (e.g. XSS, SQL injection), secure networks and access, and build in data protection from the start — secure communication as the basis of every solution.
08 — AI, ML & Agent Architecture
▾
Integrating large language models (Claude, ChatGPT, DeepSeek, Mistral) into your processes, plus designing and building agent-specific architectures — from prototype to production use.
09 — Data Engineering & ETL
▾
Data transformation and transfer between systems and formats — for example from PostgreSQL into performant, columnar Apache Parquet files for analytics and archiving.
How we work
From the first idea to stable operations — structured, transparent and at your pace. Expand each phase for the details.
First conversation & goals
▾
In a no-obligation conversation we clarify the starting point, goals and constraints — budget, timeline and your existing system landscape. We listen, ask targeted questions about your business and IT situation, and review existing interfaces and documentation. We capture the key requirements and success criteria in writing, and you get an honest initial assessment of feasibility, effort and a sensible way forward — before any costs arise.
Analysis & concept
▾
We inventory systems, data flows and processes in detail, assess the existing architecture, interfaces and data formats, and estimate risks and effort realistically. From this we produce a robust solution concept with an architecture sketch and a well-founded technology choice. Where critical assumptions remain, we validate them early with a proof of concept. The result is a prioritised implementation plan with clear milestones and a transparent effort estimate.
Implementation
▾
Implementation is agile, in short iterations with regular working increments. Automated tests and code reviews safeguard quality; version control and CI/CD make every change traceable and releasable at any time. You see results early and can adjust priorities. Security and documentation are created along the way — not bolted on at the end.
Rollout & operations
▾
We move the solution into production without downtime — for example through a phased migration with a fallback plan. We set up monitoring, backup and alerting, and hand over with full documentation and training for your team. Afterwards we support operations with maintenance, security updates and further development — exactly to the extent you need.
Which service fits your needs?
We'll advise you, no strings attached, on your specific IT needs.
