DIY Wedding

It started at an AI launch-day competition in Budapest in June 2026. We started building at 9am. By 3pm, the cost estimator and landing page were ready, and I shared the waitlist in a few relevant groups. By 6pm, I was pitching the product in the final.

The waitlist brought 124 signups that day. Sixty of them became test users, and the feature list came from them, not from me.

It's live now. One-off price per wedding, no subscription. I'm figuring out the marketing in public, including the parts I get wrong.

Still active

I ran Enlight Digital Studio from 2020 to 2025. At its peak, we were nine people, and we delivered 37 client projects across different industries and at very different scales — from one- and two-month builds to engagements that ran nine to fifteen months.

In 2025 I kept the company and renamed it Elliptic Digital. Today I use it for my client work. Most of that is ongoing work with GPI, alongside one or two smaller projects each year that come through my existing network.

2018–2025 · Startup ecosystem & education

Workshop session · Startup Szerda

I spent seven years helping build the startup community in Győr. We organised regular meetups through Startup Szerda, ran educational programmes, worked with university and high school students, and took part in Hungarian and international startup projects.

I eventually joined the board and became involved in projects across the wider startup ecosystem.

It taught me a lot about building communities, designing programmes, working with very different groups of people, and turning an idea into something people actually show up for.

AI Build Ideathon · hosting the programme

I was a key part of organising all but one of the six Ideathon events we've run so far.

These were usually weekend-long programmes, starting Friday afternoon and ending Sunday afternoon, with 40–60 participants, a full professional programme, mentoring, and a pitch competition at the end.

At the 2025 AI Build Ideathon, I hosted the event and was responsible for the full professional programme, from the structure and content to running the event itself.

Client work

Current client workMedical softwareNDA

Most weeks I'm designing the interface for a blood logistics system used in a medical setting. I can't show you the work because it's under NDA.

It's still an important part of what I do. Working on software that has to work in a real operational environment keeps me close to the problems, constraints, and decisions that come with building software for real people.

The build notes

Every decision that costs real money or real time.

I'm building and selling my own products alongside client work. Every decision that costs real money or real time goes into an email: what I chose, what I passed on, what it cost, and what actually moved the numbers.

I don't send it on a fixed schedule. I send one when there's something worth sending.
