Cover image for Land of Moe A custom baby
Land of Moe A custom baby blanket brand, and the storefront that sells it. Moms browse the patterns, pick the size and the back fabric, and the finished configuration lands in WhatsApp. What I built The catalogue: every pattern in one grid, filtered by the brand's own tags — animals, letters, colours, occasions — and sorted by price or date. Over a hundred tags, and search answers "bunny" with ninety-four patterns. Product pages that configure the product: type, size, backside (printed fleece, or a minky dot colour), quantity, with the front and back of the pattern shown side by side. An order that carries its own configuration into WhatsApp. Pattern, type, size, backside, price and quantity are written into the message before it is sent, so the conversation starts at the right blanket instead of at the beginning. The pages the shop runs on: how to order, washing instructions, FAQ, about — plus a customer gallery built from the brand's own Instagram posts, so the social proof lives on the site and not only in the feed. Behind the login, a back office where the patterns, tags, prices and pages live as data rather than hand-built pages. Stack Next.js, Tailwind CSS, Cloudflare. Land of Moe has been making these since 2017, and everything is made to order, so the storefront is built around how an order actually happens.

Cover image for Megaverse is a fitness club
Megaverse is a fitness club in Palembang, built as one platform instead of four disconnected tools. The public site sells the club: programs with intensity and duration, the padel club with court pricing and availability, and the club's postings. The member area is where members live day to day — registration with KTP and address, then profile, class booking, attendance and renewal history. The front desk side covers renewals and payments, gate logs, and lockers with their rentals. Behind that sits the business: a POS with products, suppliers, units and categories, employee and personal trainer records with specialisations, and finance with chart of accounts, journals, fiscal periods and fixed assets, with the heavy tables exported to Excel. Laravel with Blade, Tailwind and MySQL. Built together with Tengku Kevin Juldianto (dev.tengkukevin@gmail.com). https://mega-verse.id

Cover image for UTARA A music platform for independent
UTARA A music platform for independent Indonesian artists. An artist uploads a release, it goes live on the platform, and listeners find it through artist pages and the catalogue. Payments run through Duitku, and the whole thing runs on the edge, so catalogue pages stay fast without a server to babysit. What I built Artist and listener accounts, with an upload flow that takes a release from draft to published. Artist pages and a browsable catalogue, built for slow connections first. Payments through Duitku. A Hono API over D1 on Cloudflare Workers, with a Next.js front end on the same edge runtime. Stack Next.js, Hono, Cloudflare Workers, D1, Duitku. It is early and I am building it in the open, so the parts that exist are the ones people actually asked for.

Cover image for Evo Academy The system a dance
Evo Academy The system a dance school actually runs on. Parents enquire, students enrol, teachers take attendance at the door, packages get billed monthly, teachers get paid, and the money lands in a real ledger instead of a spreadsheet. What I built Students, guardians and registrations, so the studio can enrol a new student in one screen. Attendance per class session, on weekly schedules with teacher assignments. Packages and recurring billing, so the monthly run is a report instead of a reconciliation. Teacher payroll, calculated from the classes they actually taught. A studio POS for walk-in payments, and bookkeeping that ties the day's takings together. Stack Laravel, PostgreSQL, React, Inertia, Tailwind CSS. Built for one school first, which is why it fits the way a studio works instead of the way a generic school system thinks it should.

Cover image for This tiny Apps Script can
This tiny Apps Script can turn a Google Sheet into an automated notification system. One of the simplest automations I use: Google Form ↓ Google Sheet ↓ Apps Script ↓ Automatic email notification Instead of checking the spreadsheet manually every time a new lead comes in, the workflow can trigger an email automatically. The interesting part? You don't need to build a complicated SaaS to automate a repetitive task. Sometimes, a few lines of Apps Script are enough. I use this approach as a foundation for larger Google Workspace automation systems. What repetitive task would you automate first with Google Sheets?
