THE FOUNDER / ANDREI “PAX” POPA
I’m Andrei “Pax” Popa.
I’m the founder of PaxDynamics, based in Bucharest. I work with product teams on software R&D, AI systems, architecture, and security, connecting technical investigation with implementation and operation. I also provide fractional technical leadership and advisory work.

The Work
My work ranges from analytical platforms and agent workflows to source-level security research. I take a difficult problem far enough that someone can inspect the result, understand its limits, and decide what to do next.
I connect product needs with engineering and commercial decisions. In the Romania–China cloud and AI proposal, I offer to coordinate technical discussions, assess applications, and prepare joint projects with Romanian collaborators. The programme is exploratory; each team’s role and any implementation will be agreed separately.
Core Skills
Web & mobile engineering
Web and mobile applications, APIs, and SDKs. Connecting the user interface to data, jobs, and the systems behind it.
Security research & testing
OSCP certified. Source review, patch analysis, controlled reproductions, threat modeling, and authorized application testing.
Cloud operations & observability
Deployment pipelines, containers, monitoring, and recovery. Making service and job behavior visible to operators.
AI assistants & tool integration
Assistants connected to approved tools, with model evaluation, execution limits, and evidence for their answers.
Data & spatial analytics
Versioned data pipelines, analytical APIs, interactive maps, precise area and time queries, and saved views.
Technical leadership & R&D
Feasibility studies, architecture, scoped experiments, and delivery planning. Turning research methods into testable product workflows.
Experience Highlights
Startups
Built products for teams like Elbit, Cellebrite, Kin, Jazz and Motif. Occasional open-source contributor.
Government
Worked on nation-wide systems for the Romanian government and shipped software used in NATO exercises.

The Hackathons
I bring builders together for focused, one-day experiments at the intersection of AI, games, and security. Small teams, working demos, no pitch decks.

The Origin
I've spent the last 13+ years writing code and building in startups. I grew up in post-communist Romania in the 90s, and I was lucky enough to discover the Internet in its teenage years.
I spent way too many nights debugging servers, breaking things, and making online friends I've never met. As a teen, I was part of the hacker scene.
The Mindset
My interests range from security, cryptography, AI, algorithmic governance, to history, psychology and future studies. I'm constantly looking for patterns, loopholes, and better ways to understand how the world works.
Occasionally featured on national TV discussing cyber security and intelligence topics. I write about geopolitics and intelligence or philosophy on my blogs. I'm also translating "Morals and Dogma of the Ancient and Accepted Scottish Rite of Freemasonry" (chapters 4-32) in Romanian to share its wisdom.
The Now
These days I split my time between feeding my curiosity, building, and family.
I'm also constantly blown away by what AI enables, and I still feel like I'm only scratching the surface.
I believe in self-determination, in pursuing truth, and in using whatever skills I have to leave things a bit better than I found them. We're living through extraordinary times, and I don't want to waste that.
