Dimitrios Ntempos
Product Manager • AI, Integrations & Data
I build products at the intersection of AI, integrations, and data systems. Nine years of owning API-driven, integration-heavy products across blockchain, travel tech, and AI — from SDK pipelines and event specs to multi-agent systems in production. I work as a near-peer with engineering teams on architecture and data contracts, and I build hands-on to stay close to how AI systems actually behave. In this space I write, build, and document what I learn.
What I write
Latest essays on product thinking, startups, and what I'm learning over time.
Structural patterns in product management
Different industries. Same structural questions. Whether a feature gets approved, a funnel declines, or delivery slips, the surface changes but the underlying tensions remain. This is the operating logic I rely on when clarity competes with speed. Not a framework. Just a snapshot of how I think. Take what is useful.
Building another GPT wrapper on purpose
AI is everywhere and building with it has never been easier. Models are powerful, accessible, and here to stay. So if intelligence is becoming a commodity, what actually differentiates a product? This post is about building Easyscout, another “GPT wrapper”, and why focusing on real problems, UX, and orchestration matters more than the model itself.
