About Dimitris

Principal AI Product Designer & Builder.

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.

Professional experience

Dialectica (Contract · via Evidence-Based Design)

Principal AI Product Designer & Builder (March 2024 - Present)

Leading UX strategy and product architecture for the Origin Platform — Dialectica's multi-touchpoint, client-facing private-markets intelligence platform for self-serve research, serving PE funds, hedge funds, consultancies, and professional services firms. Engaged as Principal UX Architect since March 2024.

Lead UX architect across the multi-touchpoint platform — the web app, the Anthropic Claude connector (MCP server + plugin) in production use, the connector listed on Anthropic's Claude marketplace, a forthcoming ChatGPT surface, and the Slack and MS Teams apps in design (not yet released). One client experience, multiple entry points
Proposed and spearheading the "meet the client where they are" product strategy — remove friction by surfacing the right insights at the right time on the surface the client already works in. The strategy drives roadmap, scope, and the multi-touchpoint architecture across web app, chat surfaces, and AI clients
Heading Dialectica's client-facing AI agent — a multitool agent doing RAG and GraphRAG across Dialectica's proprietary data, the client's project-derived knowledge, and public sources; suggests contextually relevant next steps; guides clients on optimizing expert-call project requests by extracting goals, targets, and proposing direction from Dialectica's proprietary knowledge graph; uses generative UI to render answers in the most useful form per query. In alpha with selected private-equity clients since spring 2026
Heading the Origin MCP server and plugin (also PM) — built and released to Dialectica's own analysts and first customers, then listed on Anthropic's Claude marketplace as the first connector release; a ChatGPT surface is next. Owns scope, roadmap, and design; partners with engineering on implementation. Software engineering and data science built and secured the production server. Lets AI assistants read/write to the platform's content and contacts.
Created the Agent Skills behind the Origin plugin (2026) — authored and iterated the agent skills that ship inside the official Origin plugin (in alpha with selected customers, its marketplace submission next), with further internal skills in use at Dialectica; the same skills drove the building of the plugins themselves
Designing the Slack and MS Teams apps as the Origin agent's secondary surfaces (forthcoming — not yet released) — same agent, answering where clients already work, with deep links back to Origin for richer context
Prototyped full application end-to-end (data model, schema, front-end, back-end) with integrations to Gmail, Slack, and internal APIs; merged production code into Origin (animated charts, modals); designs and writes the MCP app UI in Claude Code and Cursor; engineering and data science built and secured the production server
Cross-team principal: design lead across 3 dev teams on revenue-generating 0→1 initiatives; co-owning the product roadmap with product leadership and C-suite
Collaborating with Director of UX and CPO to drive UX strategy on key business initiatives aligned with product strategy and company goals
Driving user research; mapping internal processes and creating service blueprints across business units; mapping system entities and relationships into the data model for the redesigned content platform
Continuing to mentor mid- and senior-level designers on the team — design craft, strategy framing, and cross-team collaboration. Extends a pattern that has run through every Lead/Head/Principal role since ANIXE and continues through community leadership at UX Greece
Deep domain immersion in expert networks and primary research since March 2024 — the client journey from question → expert insight → decision for private-equity, hedge-fund, and consulting users: expert sourcing, call workflows, project scoping, and research deliverables

WeatherXM (Contract · via Evidence-Based Design)

Principal Product Designer (July 2022 - May 2023)

Defined product vision, UX strategy, and hands-on design for a web3-enabled IoT weather network connecting physical stations to a decentralized data marketplace.

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 from 5,000 to 7,500+ stations, so the sellable share of the network grew roughly fivefold and the B2B data product became sellable at scale; -63% support tickets in redesigned categories (≈ $113K/yr estimated support-cost avoidance); +54% perceived utility (UMUX-lite).
Built the "Derecho" design system from scratch; redesigned mobile apps (Android, iOS) and web apps
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.
Collaborated with management to define and adapt product and company vision and strategy; mapped systems to align stakeholders
Mentored mid- and senior-level designers on the team — design craft, IoT/onboarding patterns, and cross-functional collaboration with engineering and product
