Solid architecture, from cloud to AI.

Codeflow is a Belgian software architecture consultancy. We design solution, technical and application architectures, cloud foundations and AI platforms on the Microsoft stack — with more than 25 years of experience.

Services

What we do

Two complementary areas of expertise: the architecture your systems rely on, and the AI you want to build on top of it.

Architecture & cloud

Architectures that last, from technical foundations to the cloud.

More than 25 years designing and evolving business-critical systems in energy, healthcare, the public sector and e-commerce.

  • Solution architecture
  • Technical architecture
  • Application architecture
AI

AI platforms and multi-agent systems that stay under control.

Microsoft Foundry and Agent Framework, in .NET or Python: orchestration, tools, memory, MCP and human-in-the-loop.

Architecture & cloud

Solution architecture

Turning business needs into solutions aligned with your IT strategy, standards and existing landscape.

Architecture & cloud

Technical architecture

Technical foundations, frameworks, infrastructure, performance and non-functional requirements — with security by design (OWASP) from day one.

Architecture & cloud

Application architecture

Modular design, APIs, patterns (DDD, CQRS, microservices), integration and code quality.

Building software since1998
Architecture & cloud

Cloud & DevOps

Azure PaaS, Functions, API Management, Kubernetes, infrastructure as code with Terraform, CI/CD.

Architecture & cloud

Integration & data

Messaging (Service Bus, RabbitMQ, NServiceBus), APIs, SQL Server and PostgreSQL, data migrations between platforms.

Architecture & cloud

Identity & access

Identity providers, OpenID Connect and OAuth 2.0 for business applications, APIs and agents — token-based security and least privilege.

AI

AI governance

Approved models, zero data retention, DPAs, EU data residency and sovereignty, EU AI Act.

AI

RAG & MCP

Retrieval on Azure AI Search or PostgreSQL, and MCP servers connecting agents to your systems.

AI

AI coding agents

GitHub Copilot, Claude Code, Codex: compared, adopted, governed. Vibe coding included.

Our approach

Listening first, then the right solution.

Every organisation is different. We start from your needs, your constraints and your existing landscape — not from the latest trendy technology.

  1. Listen & understand

    Your business needs, your users, your organisation, and your budget, planning and security constraints.

  2. Design

    Several options, argued and documented choices, adapted to your context and your IT standards.

  3. Support delivery

    Alongside your teams, in-house or near-shore: code reviews, standards, best practices and knowledge transfer.

  4. All the way to production

    Automated deployment, operations, monitoring and continuous improvement: the solution has to run and deliver value.

How we engage

Key missions

A few representative assignments

Energy2024 — today

Energy sector

Technical architect · AI & identity

Technical foundations of an enterprise AI platform (Microsoft Foundry, Agent Framework, Python) and its governance framework — approved models, zero data retention, DPAs, EU data residency and sovereignty. Authentication and authorisation architecture for business applications.

  • Microsoft Foundry
  • Agent Framework
  • Python
  • ZDR · DPA
  • OIDC / OAuth 2.0
Healthcare & pharma2022 — 2023

EMVO

Cloud solution architect

Azure architecture of the European Alert Management System, which helps detect falsified medicines in the EU supply chain: solution design, integrations, CI/CD, infrastructure as code and code review with a near-shore team.

  • Azure
  • .NET
  • Terraform
  • API Management
  • Azure DevOps
Energy2019 — 2021

Elia

Technical, then solution architect

Publication platform delivering grid data to ENTSO-E, ACER and open-data portals; application design aligned with the IT strategy, and architecture expertise in the group architecture and infrastructure committees.

  • .NET
  • RabbitMQ
  • MongoDB
  • SQL Server
  • Azure DevOps
E-commerce2017 — 2019

VeePee

Technical architect

Cloud-native microservices platform on Kubernetes and Google Cloud: shared .NET libraries, CI/CD pipelines, developer CLI and data migration from legacy systems.

  • .NET Core
  • Kubernetes
  • Docker
  • Google Cloud
  • GitLab CI

Also: INAMI-RIZIV (register of health-care practitioners), ENTSO-E (central authentication with Keycloak), SWDE (Python, Django, PostgreSQL) and, earlier, Fluxys, N-Allo for GDF Suez, Selligent and Allianz — in software since 1998.

AI-assisted engineering

Vibe coding, with an architect’s discipline.

We use AI coding agents and compare them on real codebases: GitHub Copilot, Claude Code, OpenAI Codex. Vibe coding is fantastic for prototypes and exploration — production code still needs architecture, tests, security and review.

We help teams adopt these tools the right way:

  • Choosing and comparing tools for your context and constraints
  • Guardrails: context files, review rules, data and security boundaries
  • From a vibe-coded prototype to a maintainable product

This website was designed and built with an AI coding agent.
