About
I’m Helen Le Thu, a senior engineer with 10+ years of experience delivering production software across Singapore and New Zealand, working with teams that include Lightspeed, Flowingly, Vacasa, Gallagher, and Westpac. I’m comfortable spanning full stack or focusing on front end, building mobile-first experiences and production-ready UI with React, TypeScript, and Node.js-backed services.
I’m especially motivated by turning design into pixel-perfect, accessible, well-themed interfaces—and by making engineering teams faster through high-quality tooling. I’ve led modernizations of legacy front-end build systems (Grunt/Rollup/Webpack to Webpack and Vite), built reusable design-system components, and implemented frontend tooling like custom ESLint plugins. On the AI side, I’ve used Claude as an assistant to automate daily work and built an LLM-based pipeline (Go, Amazon Bedrock, Claude) to extract structured product metadata to improve matching.

Work experience· 11 roles
Built and maintained customer-facing features for the Lightspeed POS system using React, GraphQL, and TypeScript. Contributed to and maintained components for a shared design system. Created custom ESLint plugins to prevent production errors during the transformation of legacy AngularJS components to React. Improved developer experience by enabling HMR in a micro-frontend monorepo. Fixed internal tooling issues in Go used as a local reverse proxy to help engineers build features reliably. Migrated build tooling from Rollup to Webpack and then to Vite for faster HMR and builds. Developed Claude skills for structured GitHub PR creation. Implemented an LLM pipeline (Go, Amazon Bedrock, Claude) to extract product descriptions into structured metadata to improve retailer product matching.
Flowingly is a low-code map and process automation platform using AngularJS and Grunt with a large monolithic repository. Transformed the entire front-end ecosystem from AngularJS/Grunt to React/ESNext/Webpack and separated front-end code from backend code to decouple releases. Built generic React libraries so teams could develop components reused in legacy AngularJS apps. Introduced TypeScript and Jest to enable typed development and unit tests even within legacy AngularJS codebases. Improved deployment and release speed and increased team productivity by enabling more independent front-end releases.
Built a fully responsive customer-facing web application for Vacasa from project start through successful launch. Owned responsive layout and theming across UI components. Delivered critical front-end functionality using TypeScript, NextJS, Material UI, and React Hook Form, with backend services using AWS DynamoDB, Lambda, and EventBridge for the homeowners onboarding workflow.
