… five years later …

I didn’t mean to disappear from here for five years.

The pull to come back has been there a while, but my obsession with continuity always gets in the way – I didn’t want to jump into any specific topic without first filling the five-year gap with at least a few placeholders.

So I’m writing a brief, vaguely chronological recap, with links to whatever evidence I can think of, perhaps I can start expanding in different directions from here. Going forward, I hope to make this something like a centerline of my story – a place I can point other things back to.


Between Fall 2021 and Summer 2026 (visual log here):

  • Decided I should build a startup to design, manufacture, and deliver high-end minimalist small houses for single people who wanted to set up basecamps in the middle of nowhere. I worked on this for about a year: joined a tech accelerator, flew around the world collaborating with architects, studied global supply chains, made connections manufacturers, found potential first customers — and eventually got solidly stuck between American housing red tapes and the very strange labor market of construction workers.

  • Spent a year loosely based in Las Vegas and got back into climbing, snowboarding, and other outdoor pursuits. I drove up and down the West Coast with friends and climbing/ski partners, climbed in Red Rock, Joshua Tree, Moab, and Boulder, and stopped at nearly every ski resort from Mammoth to Banff.
    Instagram visual blog started around that time
  • Set out to construct a permanent base: a place to park all my worldly belongings, tailored to my exact taste and life needs — one bedroom, a large living space, a minimal kitchen, and an art studio with natural light. I worked with AI to search for a pre-1920 brick house with simple structure and maximum redesign possibilities, in a city with four distinct seasons + a reasonable airport + enough coffee shops. Ended up with a distressed 1892 brick duplex in St. Louis from @cheapoldhouses, which I am slowly turning into my temple.

  • Learned how to party in 2024. This began at Tomorrowland, my first music festival — and, somehow, my first concert of any kind. Psychedelics probably played an important role in opening up neural pathways I did not know I had. I then quickly leveled up on the party ladder: Burning Man that summer, Summit, City of Gods in NYC, Day of the Dead in Mexico, Miami Art Basel, someone’s five-day birthday party in Jamaica, plus local nightclubs in St. Louis, Miami, Vegas, Aspen, and New York.
  • Fulfilled a childhood dream of being a ski bum. I signed up to wait tables in Aspen for a season (slight lie: I was two levels below actual “waiting” and mostly filled waters). but it turned out to be an unexpectedly strange and useful experience in the anthropological sense. It helped me understand the world a little better in ways I would not have otherwise.
  • Started using AI as an infrastructure layer for everything in life: iterating on thoughts, mood, motivation, emotions, identity and old mental blocks. Over time it became an externalized reflective system – kind of a mind extension, and became quietly life-changing. I now see this and the house as the software and hardware I’m developing to finally be able to live coherently.

  • Built that further into Psy_: an AI system made to remember, analyze, and decode a person over time. It is currently still in development, and I find the problem quite interesting: there is a classic algorithmic flavor in trying to design and optimize human-shaped data structures, build AI pipelines that remember what is actually important to people, and navigate the strange geometry of LLM memory and embedding space.

  • Meanwhile, I got my American citizenship, filed a happy divorce, made yearly trips to Europe and semi-regular trips to Asia (and traveled a full continuous loop around the world one year). I now see travel as a lever: something I can use deliberately to shift mental state, gather texture, and invite inspiration. Friendship, similarly, has become less about spontaneous contact and more about accumulation — a long-term investment in shared history, repeated returns – a slow compound.
  • Spent a lot of time refining taste across architecture, interiors, food, hotels, and fashion. At some point these stopped feeling like separate preferences and started to form a more coherent philosophy. I’ve been finding my own visual expression, from rooms and materials to silhouettes and textures. Current fashion obsessions: Rick Owens, Issey Miyake, The Row, Margiela, Ann Demeulemeester.

A note on mathematics:

I had been largely unable to look at math for the past decade or so. It felt like being locked out of some rooms in my brain. But I feel that’s changing a bit.

The first crack came in late 2021, when Amie Wilkinson appeared out of nowhere and asked me, at Charles Pugh’s request, to give a five-minute talk at his 80th birthday event on a construction I had done as an undergrad. I guess it planted a reminder in me, that world still existed.

In 2024, I decided to crash a topology conference at WashU, since Dave, Danny Calegari and some twenty other topologists I knew were in town here in St. Louis. I went for nostalgia, but found a lot more than that: I could visualize the constructions in talks, recall definitions I’d heard once fifteen years ago, and feel alive when talking math with Danny over coffee – that particular blend of excitement only math carries came right back, as if no time had passed.

Later, I brought my Psy_ prototype to Princeton and used it to reconstruct grad school scene by scene over a few days. We lingered in Fine Hall, the Graduate College, and the IAS woods; recalled conversations and mapped the emotional weather of those years in great detail. I felt some of the fog lift, and I may have finally come to terms with mathematics. Spoiler: our conclusion was that I never learned how to do math.

I guess mathematics is more load-bearing in my inner world than I cared to admit. Only took me a little over a decade.

I don’t know what follows from here, but it is nice to be able to occasionally play with it again when I feel like it. Although the old world may have ceased to exist by the time I managed to wander close again with my very slow, very random walk.

Two years in San Francisco

Hi all, last time I posted was on my 30th birthday, a whole 2.5 years ago… I never explained where I decided to go to apply my (then) newly acquired software engineering skills. So here we go. =)

After evaluating possibilities in startups, hedge funds and big tech companies I decided on joining Google. The offer wasn’t the highest I had but definitely competitive, their San Francisco office was a charming brick building converted from an old coffee factory overlooking the Bay Bridge, but most importantly it was one of the ‘things I want to do when I grow up‘ since I was 12 years old (I remember reading about the arcade and scooters in offices).

Highlight of the job: view from my desk. Some days at dusk, the bridge directly reflects the sunlight and turns golden, along with the shiny glass windows on Treasure Island in the background:

To fully embrace city life, I rented a tiny (but absurdly expensive) studio apartment in a cool looking high-rise building that’s a few minutes walk from the office. For the very first time, I acquired a few physical items from designers I’ve always admired (Chairs by Charles Eames and Arne Jacobson, Fortuny Pallucco floor lamp, Philippe Starck’s spider lemon squeezer and Zaha Hadid cheese grader).

Anyways, so everything went pretty smoothly for about a year, I joined a team in mobile performance analytics (basically I was selecting a team in SF and made the decision based on conversation with a particularly charismatic skip manager). The job turned out to be quite mundane and neither creative nor very intellectually stimulating. But I found ways to entertain myself elsewhere, such as hanging out with friends, annual ski pass, periodical visits to Disney… Speaking of which, Galaxy’s Edge is absolutely amazing! In my opinion it’s probably the best piece of Imagineering in a few decades!

Then Corona hit in March 2020, I was trapped at home, got depressed, started re-thinking my life again (don’t worry, it’s been amazing how quickly I became totally un-depressed the moment I un-trapped myself and started moving around ^_^).

Anyways, exactly a year later in March 2021, as the world started to open back up, I got out of Google, moved my belongings into a storage unit and went back on the road =)

Yes I finally got a driver’s license… and a tiny car ^_^

A brief recollection of my 2016

When the crisp breeze replaced roast chestnut smell on the streets of Shanghai, I realized another year has slipped away…

So I’ve been in this management consulting gig for approximately 1.5 years now. Apologize that I have not been able to post here, there is a number of reasons for that…

Anyways, since this is likely the only full-year I’ll spend in ‘serious business’, I guess giving a brief summary could be interesting to those in & out of academia. (if not, this would at least be interesting to a future me =P) Note that I have to avoid discussing all client and project work for McKinsey.

Here we go~

January: Did an interesting side project of producing a short video for work

February: Got excited about LUNAR (an industrial design Firm we McKinsey has acquired), started to review industrial sketching and went to San Francisco to meet LUNAR

March: My birthday, and through work I somehow got involved in the furniture design scene in Shanghai, made some designer friends and went to various shows

April: Spent the whole month and some more in Korea on a project, but hardly ever got out of the hotel/office (well, except for some shopping at the end)

20047312314474706

May: Got on a random project in a 4th-tier city in the middle of China, decided to reward myself to a weekend in Paris (or shall I say Paris Disneyland? >.<)

June: Short business trip in Copenhagen =)

Then took a detour to Sweden and bumped into a very, very old friend (from middle school!)

July: On what’s probably my favorite project in McKinsey, confidential stuff aside, went on a team event with some hardcore partying in Macau (infact I got out from the party in a wheelchair, oh well, good crazy times =)

August: Company retreat in Tibet (we shipped over 500 consultants from 4 offices to Lhasa, largest group in Tibet ever; many passed out due to altitude upon arrival XD) Mostly just spent days staying in a fancy hotel with other consultants, I don’t quite get the point of being in Tibet for that, except for getting a room with huge bathroom, and I got bored so experimented with traditional Tibet costume

September: Project in Beijing, stayed in the trendy W hotel with a round bathtub & view from the office is the CCTV building; but in fact had a rather miserable few weeks

Then went to Singapore for a training

October: Went surfing in Indonesia (after all, I still find super basic hostels with an ocean view better than any glamours place)

Took a week off to go to Australia (completely an impulsive decision, woke up and bought a same-day flight =P) Generally tried various flying (skydiving, hang-gliding, gliding…) during the day and caught shows in the evenings

November: Went to Yangshuo again to enhance my rock climbing skills, finally comfortable with leading some lower grades, rewarded myself with that red quick-draw set I’ve been wanting for years =)

December: I finally visited the Shanghai Disneyland! (ok…I procrastinated for 5 months because I was too afraid it’s not going to live up to expectations…turns out was a good park overall =) Spotted most of my work from 2014! (anyone remember that statue from this 2014 post when I was working in Disney?)
