Selected Projects (I)
MONOMax EPL Licensing Portal
Jasmine Technology Solution
A full-stack SaaS platform that issues and verifies English Premier League commercial-broadcast licenses for Thai venues — restaurants, hotels, and pubs. Business owners sign in with email OTP, register their company and each physical venue with its screen count, and the system provisions the required MONOMax Sports Premium accounts while guaranteeing — enforced at the database level — that every account is bound to a single active venue. Admins review submissions in a dedicated console with its own auth realm and issue a verifiable digital certificate, complete with an in-house-generated QR code, for each approved venue. Built with Next.js 16 (App Router) and React 19 in strict TypeScript: two isolated better-auth realms for users and admins, MongoDB/Mongoose, zod schemas validated identically on client and server with react-hook-form, an interactive Leaflet venue-map picker, presigned document uploads to S3-compatible object storage, transactional email, and Tailwind v4 with shadcn/ui. Containerized with Docker and shipped through a GitHub Actions → GHCR → cloud-VM (Caddy) CI/CD pipeline, with PDPA-conscious data residency. Delivered as a focused 3-day sprint.
RS TROPHY (rs-trophy.com)
RUAMSUK PLATING LIMITED PARTNERSHIP
A unified e-commerce and management platform for custom trophies, plaques, and medals — consolidating fragmented legacy brands into one high-performance system. Built as a Bun monorepo: a localized, SEO-optimized Next.js storefront, a real-time ElysiaJS API, and an admin console that share Mongoose schemas and types through a common workspace package. Runs on MongoDB with Redis caching and Cloudflare R2 object storage, containerized with Docker and deployed on Railway — and ships an AI copilot for natural-language shopping assistance.
LOOKLOOK Marketplace (Mercur)
Jasmine Technology Solution
A B2B2C multi-vendor marketplace for LOOKLOOK PET, built on Medusa.js 2 and the Mercur framework across four surfaces — API backend, customer storefront, admin panel, and vendor panel. Took over as sole maintainer after the senior engineer departed, delivering 100+ commits over 4+ months of solo ownership. Shipped a workflow-based refund system, dual-mode product expiration (relative days vs. fixed date), a robust inventory system with automatic stock-location linking, order management with one-click redemption and CSV export (Asia/Bangkok time, MinIO-backed), sales-channel filtering, seller custom slugs / profiles / ranking, bulk admin actions, and a Medusa Sprint-46 upgrade — plus bilingual TH/EN deals, atop Omise (Thai PSP) payments, vendor commissions and payouts, product reviews, and Algolia search.
Prettier Config
Personal Projects
The fastest way to build, share, and try a Prettier configuration — visually, in the browser. Runs the official prettier/standalone fully client-side for instant live formatting, with a CodeMirror 6 editor spanning JS/TS, CSS, HTML, JSON, Markdown, Vue, and more, plus shareable URL-encoded configs and i18n. Built on Next.js, React, TypeScript, and Tailwind CSS v4 with shadcn/ui on Base UI.
Selected Projects (II)
LOOKLOOK PET — Partner Portal
Jasmine Technology Solution
Lead developer of the B2B partner portal for the LOOKLOOK PET platform — the self-service console where venues and brands manage their presence. Built and owned the majority of the codebase (~55% of commits across roughly 11 months) and drove the feature set end to end: venue management with a claim-an-unlisted-place flow, coupons / deals / rewards with redemption tracking, announcements and a redesigned notification center, role-based team management with email search, a partner verification and access-request workflow, profile and payment settings, avatar upload with crop + WebP resize, an analytics dashboard, and multilingual SEO (sitemap + hreflang). Next.js 15 (App Router), React 19, Tailwind v4, Radix UI, and TanStack Query on the front; NestJS 11 with MongoDB/Mongoose, Redis, BullMQ, and NATS behind a Swagger API secured by better-auth — unified by a custom design-token system, containerized with Docker, and deployed on Railway.
Online Poker Game
Freelance with friends
A real-time multiplayer online poker game featuring Server-Sent Events for live updates. Built with Next.js and PostgreSQL for a seamless, interactive card gaming experience.
LOOKLOOK PET
Jasmine Technology Solution
Architected and scaled a multi-service pet-parent community marketplace — 15+ NestJS microservices communicating over NATS, backed by MongoDB with Redis caching and BullMQ job queues, fronted by Next.js + Radix web apps and a Medusa commerce layer. Led the infrastructure migration from Tencent Cloud VMs to Railway, running a single Dockerfile across Production and UAT via environment config wired through GitHub CI/CD, and migrated object storage from Tencent COS to Cloudflare R2 for cheaper, S3-compatible asset delivery. Within the platform, led the partner-facing B2B portal (partner.looklook.pet) and took over sole ownership of the Medusa/Mercur multi-vendor marketplace after the senior engineer left.
