Real builds for real clients — multi-tenant restaurant SaaS, online ordering with HK payment rails, multi-region AWS migrations, and trilingual foundation sites. Hong Kong, Singapore, Taipei.
Next.js 15 ordering site for a multi-store F&B brand. Cart, member login, and promo codes feed three live payment rails — Mastercard MPGS, WeChat Pay, and Alipay (via Swiftpass) — reconciled by a Fastify webhook that links every transaction back to its order in Postgres.
Vue 3 + Vuetify build for a Hong Kong charitable foundation. EN / 繁中 / 简中 i18n via vue-i18n, filterable CSR-news archive, Tiptap editorial pages, and an AWS SES intake with auto-reply for the contact form.
Terraform-managed EKS 1.33 across Hong Kong + Singapore. Temporal v1.28 dispatches crawler / transform / load workflows to a pool of worker nodes, which stream parquet into an S3 data lake. Every workflow is replayable, every node is provisioned in HCL.
Full restaurant operating system. Rust/Axum + Next.js 16 multi-tenant backend (POS, KDS, queue, loyalty, inventory, refund cascade) deployed on self-hosted k3s, plus two Flutter apps — staff (waiter / cashier / KDS / QR attendance) and 8plus1 customer companion (loyalty, reservations, queue join).
Every engagement ships a single before/after metric — minutes saved, tickets deflected, cost cut. If we can't measure it, we don't claim it.
Most of our builds are private. We share full decks, code samples, and reference calls under NDA — usually within one business day.
Every project ends with a handoff: the repo, the infra, the docs, and a recorded walkthrough. No retainer required to keep the lights on.
