About
I’m Tracy Nguyen, a senior frontend engineer who enjoys turning complex internal systems into reliable, fast, and delightful web experiences. Over nearly a decade, I’ve built infrastructure and developer tooling across React and TypeScript, integrating REST/GraphQL-like data flows, real-time updates, and modern state/data management to reduce operational friction for engineering teams.
In recent roles at Atlassian and AWS, I focused on consolidating fragmented dashboards into unified SPAs, improving performance for large datasets, and standardizing UI patterns to eliminate inconsistent state. I also build practical automation—like log-to-summary experiences and assistant features—to help teams resolve incidents and operational tasks faster, with strong attention to testing, accessibility, and developer experience.

Work experience
Built a unified React 18 + TypeScript service catalog using Redux Toolkit and TanStack Query to resolve ownership-data fragmentation across internal wikis and tools. Replaced a multi-dashboard alert workflow with a single React SPA aggregating CloudWatch, Bitbucket Pipelines, and Splunk via WebSockets (Socket.io), improving incident response from tab-switching to a drill-down view. Ported legacy AngularJS dashboards to React 18, standardizing on TanStack Query and Atlaskit to eliminate duplicated UI and inconsistent state. Implemented an Express-based API gateway to normalize common read operations across internal services. Improved performance on heavy dashboards by optimizing queries and virtualizing large lists (react-window) to reduce payload size and eliminate browser freezes. Integrated LLM-assisted summarization of deployment failures and an AI-driven component for on-call handoff note suggestions, evaluated with LangSmith.
Developed a React health dashboard (Vite) aggregating CloudWatch alarms and AWS Config compliance to provide per-account scorecards. Built a self-service IAM credential request app using React, Lambda, and DynamoDB with TTL expiry plus policy validation and Step Functions approvals to reduce credential wait time from days to minutes. Created a Cloudscape-based tagging tool to identify untagged resources and apply bulk tags via the Resource Groups Tagging API. Implemented a React cost anomaly viewer using Cost Explorer and linking spikes to CloudWatch metrics and deploy times. Generated context-aware AWS CLI commands in a React app using AWS SDK v3, and orchestrated fleet-wide health signal aggregation via an Express service surfaced in the React frontend with TanStack Query. Added Jest + React Testing Library regression tests for critical dashboard flows.
Built a React (Vite) + Express + PostgreSQL project management dashboard with Passport.js authentication, consolidating staffing, budget, and status into a role-based view. Developed configurable React export UI to define field mappings and formats, backed by Express generators replacing ad-hoc Python scripts for client exports. Created a lightweight feature flag service with an admin UI, Express API, PostgreSQL storage, and a vanilla JS client snippet, enabling runtime toggles and scheduled rollouts via node-cron. Delivered a single-file HTML + vanilla ES6 reporting tool that required no build step for non-technical staff. Migrated the main app from Webpack to Vite to cut dev startup time significantly and improved hot reload performance. Started a shared React component library in Storybook with CSS Modules to standardize UI elements across internal tools.
