An explorer at the seam of the digital & the ancient.

Wichaa practitioner · Developer · Fixer

A wichaa practitioner — I make things that work like magic, with digital tools.

HODIE — it gets done today.

Some call me NaN. In town, คุณแนน.

Rates →

I build small tech, run a few quiet businesses, write code for hire, and move between worlds — Thai, Indian, American, and some off every map.

I veil most of it. The whole is a lot to hand a stranger at once, so I've split it into rooms. Enter the ones that call you.

I tend a shrine to Saint-Expédit — the red roadside kind. Ask, it's done today, the debt gets honored. I work the same way.

Hiring me? Skip the delicacy — prices below, no one to charm first. Where I live, แพงไหม is manners.

— NaN

The Unlisted Work

Some things never go behind glass. I've carried messages across borders no map shows, and left offerings for things that answered back. If you know why you're knocking, you know how to ask.

For the ones who count

Number magic

The Saturn yantra

Σ = 15
492 357 816

Every row, column and diagonal sums to 15 — the Lo Shu square, the seal of Saturn, older than the alphabet.

The taxicab

1729

= 1³ + 12³ = 9³ + 10³

The smallest number that is a sum of two cubes two ways. It rides the centipede above, in binary — the katha you already passed.

The attractor

6174

a fixed point

Take any four digits, not all the same. Sort them high, sort them low, subtract. Repeat. Every road runs to 6174 — Kaprekar's constant.

Constants

φ1.61803398…
π3.14159265…
e2.71828182…

eiπ + 1 = 0

Arithmetic, geometry, analysis — the whole of it in five symbols and one line.

One number, many masks

bin0b11011000001
oct0o3301
hex0x6C1
doz1001₁₂
romMDCCXXIX

Every one of these is 1729. A number wears many masks — so do I. Not a Number.

The Debt, Named

What it costs

The red saint's bargain is plain: ask, it's done today, settle the debt in full. Vague debts insult everyone — I name mine first.

First job

The Small Favor

฿25,000

≈ $750 · one day, fixed

One problem, one day, paid up front.

Find out cheap whether I'm any good. Bring one stuck thing — a broken pipeline, a misbehaving dataset. By evening it works, or you have my reason why not. Most people start here.

Ask →

Standing claim

The Working Month

฿170,000

≈ $5,000 · per month, capped

Half to start, half at the turn. Either of us walks at month's end, no reason owed.

A hundred legs on your problems — research, building, crawlers, fixing. First call on my hours, a line that answers same-day. For people tired of explaining themselves to someone new each time.

Ask →

By the problem

The Unsolvable

฿120,000 and up

≈ $3,500 · quoted whole, up front

Half to start, half on delivery. The number never moves.

The thing everyone else called impossible. I go all the way down — deep research, a swarm of crawlers turning every stone — for one fixed number, not an estimate that grows in the dark. If I can't do it, I say so for free.

Ask →

Baht or dollars — transfer, PromptPay, card. I start the day the first half lands. No meter: an outcome, at a named price.

Work with me

The reciprocal contract

Bring me the thing everyone else called unsolvable. A hundred legs on one problem, starting the same day — the way the red saint likes it.

I name the debt up front and it doesn't move — half to start, half on delivery. No surprise bills.

The Ledger

Done today

The saint counts in favors, so the page runs a ledger — one line a day, the finest thing finished. The workshop writes it itself.

  1. Opened Exceptional Magic — the four number systems you can still divide in, of size 1, 2, 4 and 8, and the road from the last of them to the 248 dimensions of E8. The paper it reads is licensed against derivatives, so nothing on the site is a copy of it: every table, picture and number is computed in the repository from the definitions, and 139 checks pass before the build will publish. The wheel is the picture worth the visit — 240 roots laid flat on the one plane where the whole thing turns, thirty clicks to a full turn, 6,720 lines joining every pair sixty degrees apart, and the three colours are triality’s own cut of it, 84 standing still and 78 turning each way, a split found by search here rather than carried across. Thirty-four references stand on the credit page with links, and the thanks run back to Hamilton and Graves in the 1840s. Two more opened the same morning: The Three-Body Problem — thirteen chapters, 34 equations each read out loud in a sentence beneath it, and nine periodic orbits found on this machine rather than copied, three of them choreographies with all three bodies on one track — and Goin’ Fast, twenty measured speeds from a racing snail at 0.00275 m/s up to light itself, each one carrying the arithmetic that got it.
  2. Opened Black Holes, Drawn — a black hole built out of its own equations rather than borrowed from a photograph: all 49 pictures on the site were computed here, each dot of them a ray of light run backwards through u″ + u = 3u², and the same equations run again in the reader’s browser for anyone who wants to tilt the orbit themselves. The arithmetic is left where the sky can check it — the Sun’s horizon at 2.954 km and the Earth’s at 8.87 mm, a 40-microarcsecond ring predicted for M87* where the Event Horizon Telescope measured 42, and 53 predicted for Sagittarius A* where it measured 51.8 — and the past page gives the credit back to the ones who came before the discoverer, down to John Michell, rector of Thornhill, whose letter of 1783 reached the size of a black hole a hundred and thirty-three years early. Seventeen pages, 89 named sources, and a shelf where Rahu, Charybdis, the Emu in the Sky and Ginnungagap each stand beside the physics they rhyme with and the place the rhyme gives out. Quantum Computing, plainly opened the same evening — 39 events from 1900 on, ten chapters with nine demos to press, seven ways to build a qubit with the biggest machine named on each, and a Now page that refreshes itself every Monday.
  3. Opened Roads of Chiang Mai — the square of 1296, four rings around it, and 6,934 km of road between, counted off the map rather than described: 31,668 intersections, 3,733 named sois, and a grid score of 0.67 inside the moat against 0.07 out at the third ring, where 35% of lanes end blind against 14% in the old city. Seventeen sheets from 1693 to 1959 stand beside the count, and the 1931 city map at 1:5,000 is the one worth the walk — it labels the moat คูเวียง KOO VIENG CANAL, names eight gates including ประตูขัวก้อม, the gate of the short bridge, and marks the teak houses by name. The road words of Kam Mueang are given their own shelf — hom, khua, chaeng, kat, in script, sound and root — and every page carries English and ไทย.
  4. Opened Pike Place Market — a Seattle district counted inside its own fence: the city’s overlay polygon, 30 corners and 12.83 acres, answering yes or no to every point before it goes on the map. Five bodies count the same place and come out at 153, 473, 170, 215 and 530-odd, and the page sets them beside one another rather than choosing — a licence file cannot see the daystall craftspeople and farmers who trade under the Market’s own permits, 383 of them, so the Market’s roster was read instead and 202 placed on the city’s address file, on a layer of their own. The licence dates carry the finding: median tenure inside the line runs 24.7 years against 18.7 just across it. An at-this-hour panel reads nine parts of the Market against the clock in Seattle, and a part that publishes an opening hour and no closing one is left unlit rather than guessed at.
  5. Opened The Mae Hong Son Loop — 600 km of northern road counted rather than repeated: 1,864 curves and 110 hairpins measured off OpenStreetMap geometry, and the page names the ruler it used, because a road has a curve count the way a coastline has a length — measured at 30 metres the same road gives 1,310. Beside it stand four burning seasons of daily PM2.5 for every town on the circuit, where Pai reads 3.0 µg/m³ in July against 29.8 in April, 9,319 places on the map, a seven-question sorter that comes out at 761 workable plans, and English and Thai on every page. Two more opened the same day: Muay Thai — the eight limbs, the thirty named techniques and 527 gyms mapped across 58 countries — and Hand Poke, 28 traditions of marking skin by hand across 42 countries, where Burmese, Northern Thai, Spanish and Samoan sources each reach for the same comparison — the tattoo is clothing — having never read one another.
  6. Opened The index — one address that counts what the workshop holds: 301,750 records across 18 corpora, 102,462 pages on 20 sites, and 49 public repositories, each corpus standing beside its count, its provenance and its licence. A roster file written the same evening now writes the sibling row, the sitemaps and the machine files across the fleet, and the whole of it went out under CC BY 4.0 — the price is attribution, and the work can travel.
  7. Opened Care Abroad — 342 records on going abroad for treatment, 244 published prices each carrying the date it was read, and 35 hospitals written up beside 17,508 more read off the map. The law grid is the part that took the reading: one question down the side, one country across the top, 151 readings across 56 countries, and every cell a named instrument with the date it was read rather than a colour standing in for the law — where a cell is empty it says which door was shut. Three more directories opened the same morning: Basque Tables, Pink Box and Amulet Atlas.
  8. Opened Carolina Barbecue — 178 hand-written records for the styles, sauces, dishes, pits, people and words of North and South Carolina, every field marked with where it came from and 590 named sources standing behind them. The map carries 58 places written up by hand and 335 more read off OpenStreetMap, 68 bottles were read off their own labels for sugar, first ingredient and the maker’s town, and a drawing of the hog shows which part of the animal each style takes — so the old argument between whole hog and shoulder can be had standing in front of the pig.
  9. Gave every numbered source on สุขภาพคนข้ามเพศ · trans health and the registers beside it somewhere to go when its page has closed — the source stays named and stays numbered, because it is why the line says what it says, and its [1] now opens the copy held in the web archive wherever one was found. A check before publishing holds the whole site to the same reading: a page may name a source that has gone and print the date it was read, and what it hands a reader is a door that opens.
