I turn complex systems into platforms teams can trust.
Cloud-native architecture, legacy modernisation and hands-on delivery for organisations where the software has to survive real business, security and production constraints.
Architecture becomes valuable
when it reaches production.

What I do
From architecture decisions
to software that runs.
I work at the point where system design meets delivery. That means shaping the architecture, writing the critical code and leaving teams with systems they can operate and evolve.
Expertise
The hard parts,
made workable.
Legacy modernisation
Incremental routes out of monoliths and ageing services that protect existing callers, data and operational continuity.
Oracle PL/SQL · SQL Server
.NET Framework · WCF
Hands-on architecture
Architecture decisions grounded in implementation: APIs, domain models, event flows, deployment paths and the code behind them.
C# · TypeScript · SQL
DDD · CQRS · Event-driven
AI-assisted engineering
Deterministic guardrails around generated code, so teams can distinguish validator-clean output from software that is genuinely safe to run.

Evidence over
adjectives.
Selected engagements where the architecture had to answer to production.
Making generated modernisation code reviewable.
A toolkit that turns an Oracle PL/SQL monolith into compiled, runtime-verified Kotlin services, one business slice at a time.

Runtime proof
Human sign-off
The problem
Translation was not the real risk. Trust was: reviewers could not tell which code was understood by a human and which was inferred by a model.
My contribution
I owned the generation half of the pipeline, adding persistent markers for model-authored logic, anti-pattern validators and readiness classification.
The principle
“Validators are green” and “safe to run” are different states. The handoff report makes that difference explicit.
A valuation data platform, from first endpoint to production.
Designed and built a greenfield platform that validates, parses, indexes and redistributes appraisal reports.
- Design choice
- Reporting schemas discovered from storage instead of seeded by hand.
- Result
- A new standard can be onboarded by file upload, without a migration and release.
Pricing advice that degrades in a way users can trust.
Backend design for new-build valuation, where comparable sales are scarce and reliability matters as much as the number.
- Core logic
- Price-per-m² computation and indexation at project, property-type and property level.
- Fallback
- Postcode cluster to national data, gated by reliability at every step.
From stale batch reporting to live operational supervision.
Modernised a legacy estate built on .NET MVC, SQL Server 2008, SSAS, SSIS and large stored procedures. The rebuild pushed live state to the browser, replacing information that users had to request and wait for.
“The change that mattered wasn't the framework. It was moving supervision from something you requested to something that was simply true on the screen.”
Designing an Azure-native platform for external users.
Cloud-native development across the YOSS platform: microservices and Azure Functions, Service Bus integration, B2C authentication for external users and geolocation-aware search.
“The valuable part was the design work: proposing approaches to senior Microsoft architects, defending them, then turning those decisions into working software.”
A working principle
“An architecture decision that never gets implemented is just an opinion.”
So I stay close to the code.
Experience
A decade of systems
that had to hold up.

About
Based in Utrecht
Working across Europe
Curious enough to challenge the design. Practical enough to ship it.
I'm a solution architect and engineer at Xebia in the Netherlands. Before that, I spent six and a half years as an independent consultant, mostly modernising the systems behind EDF's new-nuclear engineering supervision.
My best work sits between disciplines: understanding the business rule, drawing the system boundary, implementing the difficult path and making sure the result can be operated by the team that inherits it.
