React/Next.js · Elixir/Phoenix · LiveView · Go · PostgreSQL · WebSocket

• Work full-stack across the entire service layer — Elixir/Phoenix microservices, Phoenix LiveView, Go services, and React/Next.js frontends — owning key frontend surfaces including the React Middle Office application.
• Lead a 10+ person cross-functional team (Elixir, Go, Java, Flutter, ReactJS); executed parallel Elixir-to-Go migration — ran both systems side-by-side with full compatibility, then cut over with zero downtime, optimising query strategy to keep all API response times below 400ms.
• Designed runtime-configurable Sales Hierarchy permission system supporting 5 levels of dynamic access control, eliminating manual permission updates for 200+ sales agents.
• Optimised complex PostgreSQL queries on high-volume fintech datasets, cutting average query time from 800ms to under 150ms on tables with 50M+ rows.
• Act as last line of defence on production incidents in a live trading environment — diagnosing, mitigating, and running post-mortems under real money and real time pressure.
• Rolled out AI-assisted development workflows (Claude Code, Cursor AI) across the team — establishing review conventions and prompt patterns that shortened code-review cycles and cut time spent on boilerplate.

2022 - 2025

React 18 · Next.js · TypeScript · Turborepo · Storybook · AG Grid · Web Workers · Elixir/OTP · TimescaleDB

• Architected trading platform as 6 interconnected Elixir umbrella apps on GCP/Kubernetes, processing 5,000+ WebSocket market ticks per second with sub-100ms latency.
• Architected a Turborepo monorepo powering four real-time Next.js trading applications — asset management, backtesting, alarms, and forex analytics — with shared infrastructure for authentication, React Query data access, Recoil state, generated API types, cross-tab synchronization, and observability.
• Designed a Web Worker-based realtime engine that owns the WebSocket streams, merging and throttling high-frequency updates off the main thread to keep AG Grid trading interfaces responsive.
• Grew a shared Storybook design system to 20+ reusable components used by designers and developers across all four applications.
• Built a per-user multi-account engine running 50–100 Binance accounts per user, each as an isolated GenServer under a DynamicSupervisor, so one account's failure never cascades to another.
• Engineered a rate-limit-aware execution layer pushing tens of thousands of API calls in seconds within exchange limits — survived the worst-case burst of closing and reopening 300 positions per account across hundreds of accounts with no dropped or duplicated orders.
• Built the backtesting engine over 1B+ historical records, backed by 2B+ time-series data points in TimescaleDB — parallel strategy simulations replaying 3+ years of market history.
• Owned full delivery lifecycle: system design, CI/CD pipelines, Kubernetes, and 24/7 incident response — maintained 99.95% uptime across all services.

2019 - 2022

React · Next.js · Vue.js · TypeScript · Node.js · Nx

• Set frontend architecture and standards across 4 international products — component structure, state management (React/Redux, Vue), performance budgets, and SSR/SSG rendering strategy — and reviewed the code that shipped against them.
• Led cross-timezone delivery for clients in the US, Canada, Malaysia, and Singapore — running standups, sprint planning, and retrospectives, and reporting progress directly to overseas stakeholders.
• Coordinated the Vietnam engineering team as on-site lead — translating product requirements, unblocking developers, and mentoring engineers on the codebase.

2019 - 2022

Next.js · React · Material UI · Tailwind CSS · Cypress · Google Analytics

• Owned the desktop frontend in a two-engineer team modernizing Malaysia's largest e-marketplace (8M+ monthly visitors) from legacy PHP rendering to React and Next.js.
• Rebuilt 10+ production pages and API-connected workflows — homepage, search, and listing-detail experiences for 100k+ active users.
• Raised Lighthouse performance from the 60s to the 90s through lazy loading, bundle reduction, and production CSS cleanup.
• Built reusable UI patterns, partnered directly with product and design, instrumented analytics, and authored 300+ Cypress end-to-end tests.

2019 - 2022

React · Vue.js · Nx · Drag & Drop · Calendar & Scheduling UI

• Built two flagship product experiences for an Executive Assistant productivity platform: a Digest Builder with complex, smooth drag-and-drop section editing, and a customized React scheduling calendar.
• Extended calendar behavior for multiple invitees, summary views, and best-match time-slot selection — beyond standard scheduling components.
• Developed reusable React modules in an Nx monorepo and contributed to the Vue.js administration application, collaborating directly with the US product owner.

2019 - 2022

Vue.js · Shared Application Platform · Gridsome · SSR

• Built and maintained 20+ Vue.js mini applications for a digital signage platform inside a single repository, using shared infrastructure and condition-driven application rendering.
• Created reusable frontend modules for the in-product app ecosystem and contributed to the Gridsome SSR marketing website, improving page speed and SEO.

2019 - 2022

React PWA · IndexedDB · Dexie · Offline Sync

• Built an offline-first React PWA for field photo and form capture using IndexedDB/Dexie, queued synchronization, parallel replay, and server-side deduplication — reliable data capture in low-connectivity environments.
• Delivered supervisor and administration dashboards for monitoring field operations.

2017 - 2019

Vue.js · Elixir/Phoenix

• Led product development of Urbox — a shipping platform consolidating orders from 5+ e-commerce channels (Shopify, Amazon, eBay, WooCommerce) into a single fulfilment dashboard, built with Phoenix API and background job processing.
• Delivered admin interface and end-user app 2 weeks ahead of schedule using VueJS, collaborating remotely with Singapore-based product owner.

2012 - 2017

PHP · Zend Framework 2 · JavaScript

• Led a team of 5 engineers delivering 10+ web projects for Wall Street English, Green Academy, Panzani and other enterprise clients.
• Managed end-to-end project delivery including client requirements, technical architecture, and production deployment.
