Notes on data, AI, IT
and security
No marketing fog. The way I think about real problems with founders and managers.
Cloud vendor lock-in: the cost that does not appear in the invoice
Dependency on a single cloud provider looks cheap on paper until the moment you need to renegotiate, migrate, or recover from an outage. What to account for before you are locked in.
Internal APIs as the backbone of IT architecture
Why companies that treat internal APIs as technical details pay a steep price with every integration and every change.
Event-driven architecture: what decoupling services actually buys you
A plain explanation of event-driven patterns for owners and managers - what problems they solve, what new problems they introduce, and when the tradeoff makes sense.
Observability for product teams: what logs, metrics, and traces actually give you
A plain walkthrough of the three observability pillars and why the combination matters - written for technical owners who want to understand what they are paying for.
Feature flags: how incremental delivery reduces release risk
What feature flags are, why teams that use them release faster and break things less, and what an owner or manager needs to know before adopting them.
Vendor concentration: the hidden single point of failure in IT
Why depending on a single infrastructure or software supplier is an operational risk, not just a negotiation position.
Kubernetes: what founders discover after the migration
An honest look at the operational and financial realities of Kubernetes for mid-sized companies - what the container adoption presentations leave out.
API-first architecture: the business case for owners who do not write code
Why API-first is not a technical preference but a business decision about how the company will integrate, scale, and switch vendors.

Internal developer platforms: why this is a leadership question
What an internal developer platform is, why the approach is gaining momentum, and what it has to do with development speed and operational control.
Feature flags as a deployment risk control tool
How feature flags change the logic of releasing software and why this is a management question, not just a technical one.
Technical debt: how to talk about it with your team and make decisions
Technical debt is one of the hardest topics for conversations between technical and non-technical leaders. I offer a language and a structure for that conversation.
