Systems Architecture.
Enterprise systems architecture for institutions, corporations, and serious platforms. More than 20+ years designing the foundations under eight-figure platforms for the biggest banks, pension funds, and ministries in the Netherlands.
Strong architecture invites the right stack every time.
Most engagements start backward: pick the trendy stack first, then bend the problem to fit it. This one starts with the signal instead, the real problem and the real outcome the business actually needs, before a single technology gets named.
From there the system reveals itself rather than getting imposed on top of it. Domain-driven design gives every part of the business its own clear boundary instead of one tangled codebase pretending to serve five departments at once. Every decision gets documented before a line of code lands, not reverse-engineered from git history six months later when someone asks why something works the way it does.
Five surfaces, one discipline.
- Cloud-native platforms on Azure, built for scale from day one, not retrofitted once the first thousand users show up and break the assumptions nobody wrote down
- Cloud migrations of FinTech and enterprise systems, where the old system stays live and correct the entire time the new one is being built underneath it
- Multi-tenant SaaS platforms and marketplaces, architected so tenant two hundred costs the same operational effort as tenant two
- Event-driven and agentic systems wired for production, with the guardrails keeping an autonomous process from making an expensive mistake at 3 AM
- High-availability topologies with multi-region resilience, tested by actually failing a region on purpose before a customer ever does it for you
Architecture shipped where every deploy protects millions.
This is architecture proven in production, not a sandbox. It has shipped at Rabobank, PGGM, ASR, Vesting Finance, Siemens, Schiphol, and two Dutch ministries, institutions where every deploy keeps a bank moving money and an airport tracking every gate.
The same patterns now run underneath the AW Ventures portfolio: multi-brand ticketing handling real event traffic, B2B SaaS serving paying customers, and trading systems where catching a race condition protects a trade. Enterprise discipline travels intact regardless of company size. If anything, it is the advantage a smaller company gets to skip straight to.
How an Engagement Runs.
Discovery.
The real signal gets separated from the assumptions everyone has been carrying around. Constraints, budget, timeline, and the actual outcome get written down before anything else moves.
Blueprint.
A full architecture document, a stack recommendation with the reasoning behind it, and a delivery roadmap your team can actually follow without needing a translator.
Build or guide.
Either hands-on delivery from the same person who designed it, or architecture leadership embedded with your existing team until they can carry it alone.
