Certifications
Business-minded engineering approach backed by certifications in cloud, AI, data, security, product ownership and agile delivery.
Fast to build.
Built to last.
I turn business ideas into software that creates measurable impact. From strategy and architecture to development and delivery, I help companies build products that solve real problems, scale with confidence, and move faster. With expertise across cloud, backend, frontend, architecture and agile product management, I connect business ambition with technical execution.

StakeholderWe’re exploring AI capabilities for our platform but don’t know where to start.
Stijn ter SteegeI’ll evaluate the use cases, data availability, and expected ROI. From there, we can identify quick wins and design an AI solution that integrates cleanly with your existing architecture.
StakeholderThanks! That’s exactly the kind of answer I needed.
Expertise
Cloud-native Azure solutions, robust .NET development, and pragmatic software architecture.
About me
Whether you need a solo expert or an embedded team player, I adapt to the role you actually need filled.
Notes on software and AI
Short, practical pieces on building software that lasts, and on using AI without the hype.

The questions everyone wants to ask
If you have one I haven’t covered, just send me an email.
Contact meYes. From AI-powered features and integrations to proofs of concept and architecture decisions, I help translate AI opportunities into practical solutions.
No. I also contribute to architecture, technical strategy, product discussions, backlog refinement and stakeholder communication.
I volunteer as a First Aid Responder for the Dutch Red Cross. It reminds me that some incidents are more important than failed deployments.
Both involve assessing situations quickly, identifying root causes, following procedures and staying calm when others aren’t.
Close collaboration, clear communication, pragmatic decisions and delivering value early and often.
Absolutely. A large part of engineering is translating complexity into understandable business decisions.
Availability depends on current commitments, and rates depend on scope, duration and what the work actually involves. Send me an email and I’ll give you a straight answer.
