SPEC.ABOUT / 01
15 years of shipping. Two small kids. One mission.
I'm a Senior Product Manager and AI builder, based in Budapest with my wife and two young kids. Developer 2011 → CTO 2018 → Product 2022 → Agentic AI 2025. Today I lead growth and monetisation at scale, design agentic systems that run every day, and ship my own products end to end.
I've worked with big brands (Glenfiddich, Volkswagen UK, Bundesliga, Kahoot), built market-leading payment infrastructure for Hungary's largest bank, co-founded a production SEO A/B testing platform whose clients included Greenpeace, and spent four years owning monetisation for one of the world's biggest language-learning apps.
Now I'm shipping StillMind (AI-guided meditation) and HabitCycles (a habit method that keeps streaks but loses the all-or-nothing), building and shipping agentic systems and AI agents that do real work, co-organising Claude Code Budapest, and planning the next product chapter from August 2026.

Three beats, in my own words.
The bits the timeline can't carry.
Why I moved from CTO to PM
Between the CTO years and the PM role, I built a startup called Polkadot Tiger. I'd always been pulled more towards the decisions and the strategy than the code itself. As a developer I'd often find myself building things I didn't think made sense — but I didn't have the accountability, or really the role, to influence those calls.
Running my own thing meant I had to make those calls. I liked it. I was better at it than I'd guessed. So when it was time for the next move, I switched.
Changing the culture at The Constant Media
When I joined as CTO, the team were unhappy. Their personal time had been devalued for so long that estimates had ballooned — they were pre-emptively protecting their evenings, and there was a constant battle between what clients wanted and what the team wanted to do.
That was the first time I really understood how important it is to have the trust and the back of the team behind you. The biggest accomplishment was changing the culture. Pushing back on clients in reasonable ways. Asking for deadlines to move, or scope to be cut, so I could protect the team's evenings and weekends.
The team responded positively. Velocity went much higher, the team were happy, and the clients got more work shipped. Everyone won.
What I'm most proud of shipping
StillMind. It's a great end-to-end platform and it's genuinely mature: Sentry, Amplitude, a Mobile Measurement Partner tracking installs, a marketing site that's compounding traffic over time. The architecture is almost enterprise-level. I've built agentic systems for the ASO and the Apple Search Ads, and I've iterated the core product on real feedback and research.
I'm also personally proud of HabitCycles. It's a small project, but it's something deeply personal that I'd wanted to publish for years and always had blocks doing. I'm just glad I finally put it out there.
What I optimise for.
The trade-offs I make, declared out loud.
Family First
Building products to create freedom for school runs, swimming lessons, and being present.
Building for People
Products that genuinely improve lives. Impact is the measure of success.
AI-First Builder
AI compounds the work, not the slop. Idea to launch, with the quality bar held.
Freedom to Focus
10 years remote, because it’s where I thrive. Deep focus, family time, work that fits life.
The life around the work.
Where I live shapes what I can build.
I work remotely from Budapest, and where I live shapes what I can build. The rest of the page is the work; this part is the life around it, because the two aren't really separate.
How I ended up in Budapest
I was working as a remote developer and could be anywhere, so for a while I nomaded: hostels, new city every couple of weeks.
I was doing it wrong. I had to work full-time during the day, so the cycle was: relocate one weekend, work a week, explore the next weekend, relocate again. Two-week stints. Everyone else in the hostels was staying two or three days, so the people I'd just met were always gone by the weekend. I kept getting lonely.
I'd booked a flight home. I called my best friend, and he told me to get out of the hostels, into an Airbnb, and start going to expat events while I was still in Budapest waiting on the flight.
I did exactly that. The very next day I met friends I'm still friends with today. From that moment, I fell in love with Budapest as a city. The culture, the people, the weather, the activities. It became home.
How I spend my time off
- I hike.
- I play football.
- I go to the gym.
- I work on my projects and on learning.
- I read.
- I try to see friends.
- I love community events. I host a local one in Budapest, and an English-language conversation event where I help locals practise and get more confident speaking.
Why I work remote
Work-life balance matters to me, and I try to prioritise time with my kids. Remote work is a huge part of how that's possible. The time I'd otherwise spend commuting is time taken away from my family.
I love that when I finish work I can walk straight out of the office and be with my children. Those extra 30 to 60 minutes a day matter, because with normal working hours I only get a couple of hours with them anyway. If I had to commute, the lost time could be a third of the weekday I'd otherwise have with them.
That's insane to me.
What's filling my head this year.
Mostly AI, learning, and growth. I read the posts and tweets of the people building the leading AI tools. Boris Cherny is one I follow closely, and a lot of my time goes there.
Outside that, I'm enjoying reading Roald Dahl books with my children. The current favourite is Charlie and the Chocolate Factory.
What I'm working on this week.
Shipping v1.4 with sleep-story personalisation. Tripled ranked keywords this quarter via the agentic ASO toolkit; pushing toward the App Store discovery threshold.
Editing the next batch of cycle templates. Weekly newsletter shipping every Sunday at 8am CET.
Drafting the long-form post on the talks that rewired how I think about AI. Targeting publish this week.
Looking for my next mission.
My next full-time product role, on an AI-first team, building products that help people become who they want to be.
