Never again,apparently

Twenty-two years. 1,144 weeks. Seven times I could have taken the easier one, and didn't.

I told myself I would never join this kind of trip again — ever. And yet, I end up excited for the next one.

2002Hanoi

Second year of university. Nobody I knew made websites. There was no course for it, no one to ask, and no obvious reason to learn it.

I had a degree to finish.

what happened

I taught myself. Design, then HTML, then CSS, then enough PHP to be dangerous.

By third year I was freelancing. One person doing the whole stack, because there was nobody else to hand any of it to.

In 2004 I stopped freelancing and went on staff at ITB — VCCI. Several e-commerce portals over three years.

I was hired to design them, and I could build them too, so I ended up in both conversations — what the thing should look like, and what it was actually for. The second one turned out to be the one I couldn't leave alone.

That was the first time I noticed it. The design part was never the part I cared about most.

2007the co-founder seat

Three years at VCCI. Salary on time, work I was good at, a title that made sense to my parents.

Some people I knew were starting a company with two businesses in it: accounting software, and web services for small companies. They needed someone who could design and build the web side. It would pay less, for a while, and possibly forever.

what happened

I chased it.

iBOSS Technologies ran two things at once: accounting software, and web services for small companies. I had the web half.

At the end of the first year I sat down and counted what I'd made. Nearly one hundred layout designs. Just me.

I still remember the number, twenty years later. I don't remember much else about that year.

2009leaving your own company

The company was partly mine. Co-founder, my name on it, a business I'd built by hand and could describe in one sentence.

ePi Technologies was doing e-newspapers. Bigger products, real scale, an audience that actually existed. They wanted a designer. An employee. Reporting to someone.

what happened

I left my own company to go work for someone else.

Five years at ePi, full-stack design for some of the largest news sites in the country. I played a major role in a news aggregator that went on to take that market here.

Same pattern as VCCI, larger stakes. Full-stack design meant I could argue about how something should work and then go build the front of it, which made the arguments considerably shorter.

The interesting problem was never in the layout. It was in what the product was for.

2014sixteen hundred kilometres

ePi got acquired. That was the good outcome. I could have stayed in Hanoi, kept my title, kept my apartment, kept every friend I had.

The offer was Ho Chi Minh City. Design Manager for the web division — messaging, news, music, advertising, five products that most of the country already had on their phones.

The design team I would be managing did not exist yet. I would be hiring it.

what happened

I moved.

One of the five was the news app I'd helped build at ePi. I'd worked on it from the outside for years. Now I was inside the company that owned it, which was a strange way to arrive.

Six years. I built the team from zero — product designers for the products still finding their shape, and a creative team running the advertising campaigns.

The traffic in Ho Chi Minh City took me about a year to understand. Scooters weaving across every lane, no visible rule, and somehow nobody dies at the intersection. There's an unwritten rhythm holding it together.

It took me longer to notice I'd chosen the same thing at work. On purpose. Twice now.

2021giving up the title

Seven years as a design manager. I was senior, I was good at it, and the org knew exactly what I was for.

I went and asked to move out of design and into product.

what happened

I asked anyway.

I became Product Manager for the news product — which was partly the org's idea by then, and fair enough. I'd designed for major news sites for a decade, and I'd already been advising that team on interactive story formats.

Three years on reading experience. How people actually move through an article. What makes someone finish it.

The doubter showed up somewhere around here. You had a team. You had a title. What exactly are you doing.

I don't have a good answer to that one. I still don't.

2024a subject you know nothing about

News, I understood. Fifteen years of it.

The next product was a payment gateway. Money moving between businesses. Nothing about it resembled anything I'd done.

what happened

Eleven months on a payment gateway. Ideation, planning, execution, and a great deal of explaining things to stakeholders.

I was not the smartest person in most of those rooms.

That's the part I'd forgotten I liked.

2025doing it again

Twenty-one years in. The reasonable move at this point is to be senior somewhere stable and let the work come to you.

Qualgo had a design team. Three people. One of them left the month I arrived.

what happened

Rebuilt it.

Eleven years earlier I'd built a design team from nothing, which sounds like the harder version and isn't. Starting from zero means nobody is standing there while you work out what you're doing. This time there were two people already in the room, watching me decide.

Then I spent most of my energy on the part I actually came for: getting AI workflows adopted across design and product. Orchestrating agents. Prototyping web and native myself, hands on the tools, for the first time in years.

Building again, and deciding how the building gets done.

Which is what I was doing in 2004, on e-commerce portals nobody remembers, with worse tools and no idea it was a pattern. I have apparently been after the same thing for twenty-two years and I only noticed it while writing this page.

Which brings us to the actual reason any of this happened, and it isn't a strategy. Every one of these was a mess I could see from the outside, and I walked into it anyway.

Same as the mountain. Halfway up Poon Hill I promised myself I would never do that again. I'm currently looking at a ten-day trek.

2026your turn

I'm building two apps in the evenings. Writing a novel I may not finish. Prototyping in a stack that didn't exist three years ago.

I don't know whether this is the thing I've been walking toward for twenty-two years or just the next mess.

what happened
nothing here yet

I'll let you know.

NowAugust 2026

Product Design Manager at Qualgo in Ho Chi Minh City. I build design teams, and I spend the rest of my time on how design and product actually get built together. Right now that means AI workflows.

Claude Cowork as the orchestrator, ChatGPT and Codex assisting. Rapid prototyping for web and native. Two apps in progress that are entirely my own fault.

Twenty-two years of this: web designer, co-founder, lead product designer, design manager, product manager twice, and back to design leadership. Seven titles. Consistently one job.
