Diewe V.-Senior Backend Engineer
Check rate
Experience
Lead AI Ops
NieuweStroom
- Lead the AI Ops team and own how the engineering organisation applies AI in day-to-day development.
- Moved the teams from AI-assisted coding — completion and chat — to agentic development, first with GitHub Copilot and then with Claude Code.
- Optimised repositories for agents: architecture decision records as durable context, reusable skills, hooks that enforce guardrails, and conventions that make a codebase legible to a model.
- Built the verification layer that makes this safe: broad automated test coverage, review flows and tooling to judge generated output on evidence rather than on impression.
Backend Developer — Customer portal
NieuweStroom
- Built the backend of a greenfield customer portal, fully test-driven from the first commit.
- .NET services running on Azure Container Apps and Azure Functions, with .NET Aspire for local development and orchestration.
- Continuous deployment with trunk-based development: direct commits to main, feature flags for release control, no long-lived branches — carried by a fast, broad test suite.
- Designed and provisioned the Azure environments end to end as infrastructure as code.
.NET Developer — Finance back office
NieuweStroom
- Built the core .NET application for the back-office integration between the finance domain and Microsoft Dynamics 365 Business Central.
- Set up the delivery pipeline: CI/CD in YAML and Azure infrastructure defined in Bicep.
Full-stack Developer
Aevitae
- Joined as a junior .NET developer building APIs and grew into a medior role over four years and several teams.
- One of the main developers on the migration from on-premises hosting to Azure, working on the cloud architecture and the CI/CD pipelines in Azure DevOps.
- Built customer portals on Vue.js and Blazor front-ends backed by .NET APIs, plus integrations with external parties.
- Maintained the existing estate and traced complex issues across T-SQL and Oracle databases.
PHP Developer
Moventit
- Developed features for Moventit's platform in PHP, JavaScript and jQuery alongside my studies.

Summary
Backend engineer with nine years in software, six of them building production systems on Azure. I design services test-first, ship them through continuous deployment, and take ownership of the infrastructure they run on.
Since 2025 I lead an AI Ops team, moving an engineering organisation to genuinely agentic development. My conviction there is unglamorous: a strong test suite, deliberate context management and real review gates are what make AI output trustworthy. In a team I am calm and direct, and happy to dig into the hard problem.
