Paklok Hub

Paklok Hub

Why this project exists

Paklok Hub is Sim Kritamook's own project, not client work. It was built for Pa Khlok, Sim's hometown community, and is run as a free service for local residents and the small businesses that serve them.

The problem

In Pa Khlok, a subdistrict in the north-east of Phuket, people mostly find local food, shops, and services through a community Facebook group. The group works for conversation, but it is a poor place to look things up:
  • Food, services, and community news are mixed together in one feed
  • There are no categories or filters, such as "free delivery" or "open for orders"
  • Posts sink quickly, so a good shop disappears under newer posts
  • Finding a pharmacy, fresh fish, or an air-conditioning technician means scrolling post by post
The insight behind the project was simple: people don't dislike Facebook, they dislike searching in Facebook. Paklok Hub is deliberately not a social network, a marketplace, or a Facebook replacement. It is a discovery directory: what is for sale and what services exist in Pa Khlok today, and how to contact them.

The approach

The first phase was scoped to test one question before building anything larger: do people in the area want to find local businesses this way?
  • Admin-seeded listings first. No user accounts, no posting system, and no user-generated feed. Listings are added by an admin or submitted through a simple form and approved before they appear.
  • Contact is the goal. Every listing ends in a call, LINE, or Facebook button. Contact clicks were chosen as the main success metric, rather than page views.
  • Explicitly out of scope: comments, chat, payments, delivery management, recommendation engines, and AI chat.

What was built

Public site (paklokhub.com)
  • Category index, keyword search, and filters for free delivery, home delivery, and open-for-orders
  • Listing pages with a photo gallery, a fact sheet (price, hours, delivery), and a contact bar that stays at the bottom of the screen on mobile
  • An interactive map of pinned shops, with directions through Google Maps
  • Visitor ratings and reviews, shown only after approval
  • A public form so shop owners can submit their own listing, including photos and a map pin
Admin
  • An overview of live, pending, and per-category listing counts, with an approval queue
  • Approve or reject submissions and reviews, from the dashboard or with one tap from a Telegram alert
  • Listing and category editing, including a map picker that accepts a pasted Google Maps link or the device's GPS

Engineering
  • Next.js and React for the public site and admin, server-rendered for search engines, with structured data (LocalBusiness, breadcrumbs, ratings, coordinates) and a sitemap built from real edit dates
  • FastAPI, SQLAlchemy, and PostgreSQL for the API, with Alembic migrations
  • MapLibre GL with OpenFreeMap tiles for the maps: no API key and no per-view cost, loaded only on pages that show a map
  • Spam control without accounts: every submission and review is moderated, and reviews are also rate-limited per IP (stored only as a keyed hash) and protected with a honeypot field
  • GitHub Actions running lint, type checks, a production build, a migration round-trip, and the backend test suite on every push
  • Self-hosted on Ubuntu with Nginx and HTTPS

Results so far

These are the numbers that can be checked on the live site, as of 21 October 2026:
  • 11 live listings, all with photos, across 7 categories. Five categories have at least one listing.
  • 2 listings pinned on the map. The map launched in October 2026.
  • Live since June 2026.
The first phase aimed for 50–100 listings to test whether this kind of directory is useful. With 11, that target has not been reached, and this case study doesn't claim that it has. Usage outcomes are not reported yet, for a specific reason: contact clicks were chosen as the main metric, but an audit in October 2026 found the tracking endpoint had never existed, so no clicks were recorded from June to October. That was fixed on 19 October 2026. Until there is enough clean data, the honest statement is that whether residents use Paklok Hub instead of the Facebook group has not been measured.

What this project demonstrates

  • Taking a real problem in one's own community from a written problem statement to a deployed product, including deciding what not to build
  • Full-stack delivery across a public site, an admin, an API, and a database, with moderation designed for a site without user accounts
  • Running a live system responsibly: automated checks on every change, data migrations, and auditing your own metrics rather than trusting them
