About Dimitris

Principal Product Designer.

Enterprise B2B · AI product development · Discovery to production

I build AI-native products end-to-end — from discovery and strategy through to production code. With 15+ years in enterprise B2B, I specialize in turning complex business problems into shipped software.

I use AI-powered development to validate and deliver faster than traditional design cycles: prototyping full-stack applications, building AI chatbots with RAG, creating APIs and MCP servers, and pushing code to production with AI agents.

A systems thinker with an engineering foundation, I partner with product leadership and C-suite to co-own roadmaps. I drive discovery that connects user pain to revenue and align cross-functional teams. NN/g UX Master Certified.

What I'm looking for

Principal/staff IC with hybrid leadership: ambiguous B2B or AI-native product problems where design co-owns strategy; a team that invests in discovery; scale from seed to Series C, or an enterprise rewriting a core system.

WeatherXM (Contract · via Evidence-Based Design)

Principal Product Designer (July 2022 - May 2023)

Product design for a web3 weather network connecting physical IoT stations to a decentralized data marketplace.

Worked with leadership on product vision and strategy; mapped the system to align stakeholders
Redesigned the mobile app and device onboarding for WiFi and Helium stations — grew sellable-grade (QoD-passing) station inventory 667% (reconstructed baseline) while the network scaled 5,000 → 7,500+, so the sellable share grew roughly fivefold and the B2B data product became sellable at scale; −63% support tickets in redesigned categories (≈$113K/yr estimated avoidance); +54% perceived utility (UMUX-lite).
Built the "Derecho" design system from scratch; redesigned the Android, iOS, and web apps on top of it
Explored a Web AR installation-helper concept as lateral thinking around physical setup; prioritized the shipped onboarding, data-quality, rewards-transparency, IoT-display, and support/error-handling work that contributed to the measured outcomes.
