01
Cities
Citizen portals, municipal intranets, and public e-services that keep working when the city is online — and when it isn’t.

I ship platforms and products people can operate under real constraints — institutional systems, cloud-native software, and privacy-first tools like Thirty North.

The pattern that keeps showing up
People do not need another demo. They need systems that warn early, respect privacy and compliance, and still work when the next invoice — or the next deployment — changes the answer.
See how that shaped Thirty North →Selected work
Proof under constraint.
Latest first: a live privacy-first product, then institutional platforms that show the same ownership — citizen UX, bilingual delivery, and systems people can operate.
Context
The arena I know best.
A decade inside knowledge technologies (InMédia / BiblioMondo) — platforms for cities, libraries, museums, and institutions that must federate content, respect rights, and survive mass deployment.
02
Libraries
Multimedia catalogues, personal spaces, and companion apps that connect physical collections to digital convenience.
03
Museums
DAM, virtual exhibitions, and digital signage across heritage networks — rights-aware media, not just file storage.
04
Enterprises
Private and hybrid deployments for organizations that need the same platform rigor without a public-facing mandate.
Platform
What the stack had to do
Not a marketing site — an open, flexible CMS + DAM platform that creates, manages, and presents information and services to the public.
- Web portals and personal / citizen spaces
- Multimedia catalogues and advanced viewers
- Digital asset management with usage rights
- Virtual exhibitions and digital signage
- Mobile apps, newsletters, calendars, and events
- Forms, surveys, and back-office operations
- Multilingual delivery with WCAG-minded admin tooling
- GDPR-conscious handling of personal data
Deployment
Where it had to run
Same product family — different operational realities. Architecture that survives tenders, audits, and city-scale rollout.
- On-premise: institutional networks and 1,500+ public workstations
- Cloud: multi-tenant portals and government API integrations
- Hybrid: public surfaces with secured intranet cores
- Public organizations: libraries, museums, municipalities, ministries
- Private organizations: enterprise knowledge and media workflows
- Mass deployment with uptime, accessibility, and tender scrutiny
From idea to fleet
Shape the product
Roadmaps, research (SMESE / MLM harvesting lines), and stakeholder needs before a line of production code ships.
Make it durable
SPA/mobile fronts, microservices migrations, federated content, and standards that outlast a single release.
Roll it out at scale
On-prem, cloud, and hybrid mass deployment for institutions that cannot treat go-live as a demo day.
Focus
Where I create leverage.
Platform architecture, institutional deployment, and hands-on leadership — the same muscles from knowledge technologies, applied to cloud-native and AI-enabled systems.
Platforms
From knowledge platforms to privacy-first products — architecture that federates content, respects rights and compliance, and runs where the user actually lives.
Deployment
Ideation to mass rollout for public and private organizations: cities, institutions, and operators who need early warning — not another dashboard demo.
Leadership
Hands-on technical direction for teams of 10+. R&D roadmaps, tenders, and product shipping — without leaving the craft behind.
Experience
Recent roles. Real ownership.
From R&D leadership on knowledge platforms to aviation and energy markets — always hands-on, always shipping under real constraints.

Principle
Calculate what you can prove. Name what you will not pretend to know. Ship the early-warning system — not the theatre.
Honest limits are a product feature.
