Introduction

A little background on how I work, what I’ve been building lately, and how AI tools fit into that.

I’m Tamás, based in Budapest. For over a decade I worked on enterprise platforms — private cloud, CI/CD, data warehousing, high availability — often leading technical work across Budapest and Berlin. I’m comfortable deep in the stack, and I still think in terms of failure modes, capacity, and what happens after go-live.

Since 2023 I’ve been freelancing, and the projects look different on the outside: cloud-linked building automation (iNELS, Siemens, PLC environments), home and small-site control, web apps and backends for businesses that had outgrown spreadsheets. The approach is familiar though — understand the context on site, build, run it with real users, adjust what the first version misunderstood. I design interfaces when the job needs it; some of the clearest lessons came from watching someone use a switch at the wrong hour.

Over the last couple of years I’ve leaned heavily on AI-assisted development. Cursor is where I spend most of my coding time — sketching features, refining UI and backend code, and trying alternatives before committing to a direction. Models and assistants speed up exploration; architecture, review, and what goes to production are still engineering decisions I own.

Contracting fits how I prefer to work: short lines of communication, direct feedback, room to rethink when the problem turns out to be slightly different from the first conversation. I collaborate remotely across Europe and I’m most motivated when I can shape both the concept and the implementation — not hand off one half and disappear.

Passion projects

Software I develop for my own projects and initiatives — not client commissions — from festival ops to event tools, mostly pair-built with Cursor.

Stagehand

Operations software for my own Sticks + Stones–style festival work: timetables, artist hospitality, volunteer shifts, catering, and technical rental inventory in one place. It exists because the projects needed a real ops layer, not another spreadsheet — still in beta, still my favourite rabbit hole, still evolving with each season.

  • React
  • Vite
  • Python
  • PostgreSQL
  • Docker
Overview on GitHub

The Ambassador

Ticketing platform for my own low-budget, break-even–driven festival concept — ambassador codes, phased prices, guest tickets, and dashboards that make artist economics visible. Software built to test an idea the projects depend on, not a generic off-the-shelf product.

  • Next.js
  • FastAPI
  • PostgreSQL
  • Redis
  • Docker
Overview on GitHub

Nincsenek Fények!

Application stack for my own “Nincsenek Fények!” initiative — playful fact-checking for different ages, with API, content flows, and background jobs in containers. Built to serve the project’s format, not as outsourced product work.

  • Python
  • FastAPI
  • Docker
  • MongoDB
  • Celery
Overview on GitHub

Közéleti Bingó!

Event software for my own live show format: a bingo game that playfully links big political headlines to everyday life — the kind of “that’s so true” moments people already joke about. A Whisper worker listens for spoken words and marks the card; admin tooling runs the rounds. Lightweight stack, real-time room energy.

  • FastAPI
  • Whisper STT
  • Redis
  • Docker
  • Nginx

Out of office

Music, small events, and the hobbies that balance the technical day job.

Away from laptops and pipelines, most of my free time goes to collecting records and listening properly — digging for releases and living with them, not just background noise.

Underground techno has been a constant draw, especially hypnotic and deep strains. I help shape smaller gatherings that mix music workshops with audiovisual sessions, with real care for how that sound lands in the room.

I’m steadily learning live sound engineering — mixing and reinforcement as a craft, not only as someone who books the lineup.

As a beginner DJ I play for smaller crowds in the genres I care about most.

Modular synthesis has become a recent favourite: mostly in the box with VCV Rack today, with the hope of spending more time on a physical rack soon.
