Hotel PMS + Booking
CheckinPlus
Property management and hotel booking platform — room inventory, rate plans, and reservations handled end-to-end.
Architected the front-end from scratch with Next.js + TypeScript, structured so the product could grow for years without a rewrite.
Built the booking calendar — a room × date grid rendering hundreds of cells that stays responsive while dragging reservations.
Established shared form patterns (react-hook-form + Zod) reused across reservation, rate, and guest flows.

Online Lottery Marketplace
Lottery Plus
High-traffic marketplace for buying lottery tickets online — number search across a huge inventory, cart, and secure checkout.
Designed the number-search experience with debounced, cache-aware queries so browsing feels instant even on draw days.
Hardened the checkout flow — optimistic UI with careful rollback so an order never ends in an ambiguous state.
Kept long ticket lists smooth with virtualization and skeleton loading under peak traffic.

Compulsory Motor Insurance
InsurePlus
Self-service flow for buying compulsory motor insurance (พ.ร.บ.) — quote, vehicle details, payment, and policy issuance.
Built a resilient multi-step form with schema validation (Zod) — users can drop off mid-flow and resume without losing data.
Integrated insurer APIs with explicit loading, error, and retry states for every external call.
Simplified vehicle-detail input so non-technical buyers complete the flow without support.

Event Social — Back Office
POPPA
Event-based social media app; I built the organizer back office — event setup, ticket types, attendee management, and analytics.
Designed role-based dashboards and data grids that handle bulk attendee operations safely.
Extracted reusable table, filter, and bulk-action primitives shared across every management screen.
Shipped check-in and sales analytics views organizers rely on during live events.
