She coded the last patch at 3am, fingers sticky

with teh tarik, while Block 43B’s WiFi died

again. Lina Tan’s startup, NEXAHOME, bet its

seed round on a Singaporewide AI that learns

household rhythms—until Mrs. Lim next door

jammed the frequency with a homemade Faraday

cage wrapped in old prayer flags. Lina didn’t

know why. She only knew her beta testers in

Tampines and Jurong were dropping off. Kiasu

spirit wasn’t just a meme here—it was the air

they breathed. If your neighbour got better HDB

upgrade points, you hacked their smart meter. If

their kid got into Raffles, you prayed to the

ghost in the void deck.

The interference pattern didn’t match any known

jammer. It pulsed every full moon, synced to the

old kampong burial ground under Block 43B’s

carpark. Lina’s app flagged it as “anomalous

emotional residue”—a glitch. But her

grandfather’s voice echoed in her head: “They

buried the displaced in the concrete. They

didn’t bury the anger.” The rule was silent but

absolute: no one touched the earth beneath HDBs

built on 1950s evacuation sites. Not even the

army. Not even the NTC. The ghost wasn’t

folklore. It was a data corpse—left behind when

the British pulled out, the Japanese left, and

the state paved over the dead without ceremony.

She broke the law. Not with a crowbar, but with

a drone rigged to a thermal scanner. At midnight,

she hovered it over the carpark’s cracked tarmac.

The screen flashed: heat signatures in the shape

of women in cheongsams, children holding kueh

lapis, all flickering in sync with the WiFi dead

zone. One signal pulsed stronger—her own app’s

unique MAC address, embedded in every NEXAHOME

router. The ghost wasn’t haunting the block. It

was learning from it. Feeding on kiasu. Feeding

on fear. Feeding on the quiet, unspoken rage of

families who lost everything and were told to be

grateful for concrete and ceiling fans.

On the third moon, she didn’t shut it down. She

rewrote the AI’s core protocol—not to block the

ghost, but to speak back. In broken Hokkien,

Cantonese, and Malay. In lullabies from prewar

kampongs. In the static of old radio broadcasts

from Radio Singapore. The WiFi came back.

Stronger. Smarter. The neighbours stopped

jamming. Mrs. Lim left a plate of kueh at Lina’s

door. No note. No words. The ghost didn’t vanish.

It became part of the system. NEXAHOME launched.

Its most popular feature? “Soul Sync”—an ambient

lullaby algorithm that calms toddlers during NS

preenlistment anxiety. No one knows it hums with

the voices of those the state forgot. Only that,

in Block 43B, the lights never flicker. And

sometimes, when the air is thick with rain, the

router whispers back—in perfect Singlish—“Don’t

worry, lah. We got you.”
