What I believe

Think you're missing another tool or system? More often it's self-knowledge and energy.

I'm David Rozsa, a digital product architect. For more than a decade I've helped people decide what's worth building, and then built it. Alongside that I walk my own path, researching how to build on digital foundations without losing yourself along the way.

For a long time I looked for the answer in the wrong place.

Here it is in short, because you may recognise yourself in it.

  1. I thought the answer was in the next course, the next book, or an even better productivity system.

    It wasn't knowledge I was missing. It was self-knowledge.

  2. I worked twelve to fifteen hours a day and still felt I was running in place, while others seemed to pass me with ease.

    The constant drive was something I brought from home, not something I chose. When I started to take it apart, for my family's sake too, I slept better, decided with more confidence, and opportunities came more easily.

  3. For a long time a digital product really did need a team: a strategist, a designer and a developer.

    Today not every product needs a big team. What matters is knowing which tools to use and how, and who should help build it. I started as a business analyst, moved into UX, and today I also build what I design.

  4. I thought the faster I built, the better.

    With AI, things get made at lightning speed. Quality work still takes research, expertise and care: knowing what to build and what not to, what can wait, and how the product will grow. You can build a lot for yourself now, and I'm glad to show you how.

Today I'm working to bring the pace of AI in line with what ancient wisdom has known for a long time: the power of slowing down, respect for your inner rhythm, and knowing yourself first. I draw on the Vedic tradition for it: meditation, and the way I manage my energy.

If you're working nonstop too and something is still missing, maybe you don't need another system. I'm a researcher on this path, and I write from wherever I am on it.

If you'd like to talk about this, and not only about a product, just write.

What I build

I don't build what already exists; I look for the missing link. I try out on my own products what I recommend to my clients. Modulyo helps while you're still looking for the idea, theuxbites once your site is live. If Modulyo gets you as far as a working site, theuxbites takes it from there.

If you're still looking for the idea

Modulyo

It shows you where ideas can come from, then works one of them into a plan with you. One you can try out with as little time and money as possible before you take a bigger step. It goes step by step, and you don't need a finished idea to start.

Why I built it

The most common block I see isn't building. It's that people don't believe they have an idea.

About Modulyo
If your site is already live

theuxbites

It reviews your website, web shop or the screenshots of an idea: where visitors get stuck, what AI search sees of you, how you compare with competitors. Your AI assistant can reach it over MCP too. Three audits a month are free.

Why I built it

I kept seeing small usability faults that little work would fix, yet nobody did. I'd like you to come to enjoy putting people first, and I show you how.

About theuxbites

For my own use

I didn't build these to sell. Each one answers a snag in our own everyday life, and I show them because this is within your reach now too: a tool of your own for your own snag. The hard part isn't building it but knowing what to build and what to leave out, and I'm glad to help with that.

How I run my business alone

Deck

For a long time every step hung on me: research, drafts, plans, code, and when I wasn't at the desk, nothing moved. Deck is an agent system I built myself that does this work, also while I'm away, and remembers everything we've decided so far. It can't publish: every text and every decision goes through me.

Why I built it

I wanted to work like a team on my own, but not at the cost of my evenings. Now I sit down in the morning to what is waiting for my decision, and my evening stays with my family.

How I work with it
When running the household is a project too

Ledgr

A warranty card in a drawer, expired vitamins on the shelf, a bill somewhere in the inbox, and every evening the question of what to cook within this week's budget. Ledgr keeps all of it in one place: it turns the budget into recipes and a shopping list, tells us before a warranty or a medicine runs out, and keeps our documents in order. Only our family can reach it.

Why I built it

I didn't want running the house to become one more job after work. Less searching and fewer forgotten deadlines leave more time for each other, and the app grows with us as our life changes.

When there's no one to practise English with

Anne

Speaking is the hardest part of learning a language, and after the lesson there's no one to practise with. Anne talks with me out loud, works from my own grammar notes, corrects me as we go, makes flashcards and brings up topics I actually care about. As I improve, she changes with me.

Why I built it

We had an English teacher we loved. No app can copy what that teacher knew, and a personal relationship always gives more. We wanted to keep that good conversation in our pocket between lessons, so practice doesn't stop in everyday life.

One Decision

Every other week, one real decision from my own work. What I built, what I left out, what I handed to a machine and what I deliberately kept. With the reasoning, and what it cost when I got it wrong.

Not a newsletter. One decision at a time, close enough to your own work to be useful. Whether you are building a product or looking for a way to work that doesn't wear you down.
