UIUX Designer / UIUX Lead

  • Designed and shipped B2B, B2C, and B2B2C product experiences across web portals, eGift platforms, eSIM apps, promo apps, reseller back office systems, POS experiences, payment-related flows, admin tools, corporate websites, and production UI features.
  • Led UIUX work for complex product flows involving role permissions, admin and non-admin access, department-level controls, email invitations, account ownership, multi-BU structures, templates, components, parameters, and PSP-related product logic.
  • Designed eGift and payment experiences including online redeem, PDF download, eCard transfer, Apple/Google Wallet support, different-currency transfer, partial redeem/payment, physical redemption, voucher payment logic, delivery flows, and animation behavior.
  • Designed eSIM app and web experiences including buy flows, address and invoice flows, payment, how-to-use guidance, top-up, token copy, account management, passport scan, login/sign-up, forgot password, and ID scan flows.
  • Designed B2B KYB / KYC registration flows using the Societe API, covering multi-country regulatory verification, document upload, liveness verification, and company validation logic.
  • Designed Glady corporate credit card platform: KYB B2B enterprise registration, KYC employee card-opening verification, and NFC card management app flows.

Implementation, collaboration & analytics

  • Built rapid prototypes and AI-assisted product flows using ReactJS, SCSS, JSX, Tailwind CSS, Bootstrap, MUI, component systems, variables, and color library JSON.
  • Used Git, GitHub, SourceTree, Bitbucket/GitHub cloning, branch-based workflows, and pull request support to collaborate around codebase-ready UI implementation.
  • Created readable, component-based UI code and supported production UI updates for popups, banners, filters, switchers, components, variables, color libraries, and website/product UI sections.
  • Collaborated closely with frontend engineers on design handoff, component behavior, UI implementation, UI testing, bug identification, and visual QA.
  • Implemented GA4 event tracking, Meta Pixel, and Meta Conversion API (server-side); wrote custom Apps Script to pull GA4 Data API across multiple property IDs — routing conditional warning emails, zero-activity alerts, monthly reports, and API error notifications to different PMs.
  • Applied a 3D animation background in Maya and Blender to product motion, eGift animation behavior, micro-interactions, visual hierarchy, depth, timing, and interaction polish.
