MÁRK Áron GOZNER
MAKER OF INTERFACES
Senior full-stack engineer in Cluj-Napoca. I build critical banking systems and AI-assisted delivery tooling — .NET and React are home, but Java, Vue, React Native, Kafka and Redis all get used when the problem calls for them. Off the clock the same discipline goes into the kilometres.

Form. Function.
Full-stack.
I’m Márk Áron Gozner — also written Mark Gozner, or Gozner Mark in Hungarian name order — a senior full-stack engineer from Cluj-Napoca. I approach software the way John von Neumann approached a machine: find the one structure that carries the whole problem, drop everything that structure does not need, and let it be good because it is simple.
By day I design and build web applications end to end — clean interfaces, honest APIs, infrastructure that is boring in the best possible way. I care about the details users feel but never see: the fast first paint, the form that forgives, the empty state that helps.
After hours the laptop closes and the world gets painted thicker: long rides on Hungarian backroads, narrow streets in Sicily, dunes in the Canaries — always with one eye looking for the light Vincent would have chased.

The craft
Tools change; principles don’t. These are the ones I reach for when an idea needs to ship.
C# & .NET
Banking-grade ASP.NET Core services — typed, tested, observable.
React & Next.js
Interfaces from design system to App Store — Vue and React Native included.
TypeScript & JavaScript
The connective tissue — typed contracts from database to pixel.
SQL Server & Supabase
Schemas that survive audits, queries that survive month-end.
Kafka & Redis
Event-driven integrations with sub-second latencies — streams, caches, back-pressure.
Java Spring
Second backend dialect — fluent enough to ship a product in five days.
AI agents & MCP
Agent frameworks wired into Jira, GitHub and Playwright — Ambassador by title, tinkerer by nature.
Quality & DevEx
Docker, Playwright, reviews and mentoring — velocity through standards, not shortcuts.

.NET and React are where I live — but the work has never stopped there.

05Beyond the
Beyond the
keyboard
Three obsessions, painted honest — each model drawn from a real photograph.
The Rider
Give me a ribbon of tarmac, two full bottles and a slight tailwind. I ride where the wheat swirls like brushstrokes — champion stripes on the jersey optional, suffering on the climbs guaranteed.
- aero everything
- ~90 rpm
- Sunday = 120 km
The Wanderer
Narrow streets, warm stone, one scoop of pistachio. I collect alleys the way painters collect skies — Sicily started the habit; the rest of the map will have to finish it.
- Sicily
- Canary Islands
- next: somewhere warm
Two under one sky
The best adventures are shared. Dunes at golden hour, one questionable choice of football shirt, and the same swirling sky above the both of us.
