MÁRK Áron GOZNER
MAKER OF INTERFACES
I build for the web with Bauhaus discipline — strip the ornament, keep what works — and spend the saved time under Van Gogh skies: on a bike, on the road, on the terraces.

Form. Function.
Full-stack.
I’m Márk — a developer from Hungary who treats software the way the Bauhaus treated chairs: remove the ornament, keep what works, and let it be beautiful because it works.
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.
The whole toolbox
.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.

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.

- Canary Islands

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.

Five real photographs, redrawn as five little paintings — geometry from Weimar, skies from Vincent.
All five models are hand-drawn SVG — no photographs shipped, only their painted echoes.
