Who This Is For

I help companies building or operating systems on Azure and .NET when they face at least one of these challenges:

  • systems don’t talk to each other — integrations are brittle, manual, or missing,
  • you want AI in your product or processes, but need proof before committing,
  • a migration, refactoring, or architectural change feels too risky to start,
  • there is no strong senior technical leadership for priorities and execution.

The goal is simple: connected systems, less risk, faster delivery.

Service Packages

1) Azure Integration & Architecture Roadmap

Best when: you are connecting systems, migrating to Azure, or replacing brittle point-to-point integrations.

What you get:

  • target integration architecture (Logic Apps, Functions, APIs, messaging),
  • phased implementation roadmap,
  • major technical and operational risk mapping.

Timeline: 2-4 weeks Price: from €2,400

2) AI Integration Pilot (Azure OpenAI)

Best when: you want AI in your existing .NET/Azure system but need working proof before committing budget.

What you get:

  • discovery workshop mapping 2-3 realistic AI use cases for your system and data,
  • one working pilot integration (Azure OpenAI) wired into your real application,
  • production readiness notes: cost, data privacy, prompt/response logging, failure modes.

Backed by real production experience: I built and run RosterIQ, an AI scheduling product live on Azure OpenAI since April 2025. Read the case study →

Timeline: 3-5 weeks Price: from €2,400

3) Quick Technical Audit

Best when: you need an independent senior review of performance, reliability, or integration health — fast.

What you get:

  • analysis of key bottlenecks and risks,
  • prioritized recommendations (quick wins vs. mid-term actions),
  • concrete next steps for your team.

Timeline: 1-2 weeks Price: from €1,000

4) Fractional Tech Lead / Architect

Best when: you need ongoing senior technical leadership without a full-time executive hire.

What you get:

  • recurring sessions with your team,
  • review of technical and architecture decisions and priorities,
  • mentoring for senior and junior engineers,
  • support in delivery planning.

Scope: 1-4 days per month Price: from €1,600 / month
