As the founding engineer, owned both frontend and backend across the entire product:

Owned frontend architecture across 6+ product modules (AI Chat, DataRoom, Reports, Forms, Billing, Team Management) using React 18, Next.js 13, TypeScript, and Redux Toolkit
Built backend APIs for authentication (JWT, HTTP-only cookies, token refresh), user onboarding, profile management, and feature-flag updates using Node.js and Express.js
Architected an Enterprise DataRoom (Airtable-style) using TanStack Table and React Virtuoso — 10+ column types, virtualized rendering for 50,000+ rows, cutting render time from 3s to 300ms
Built an AI-powered dashboard system with natural language querying and drag-and-drop widgets, reducing UI dataset size by 70–80% via backend AI prompt filtering
Improved Core Web Vitals through image optimization, bundle analysis, and dynamic imports — LCP up 40%, bundle size down 35%
Developed real-time analytics dashboards using Recharts, ECharts, ApexCharts, and D3.js with drill-downs and memoized rendering
Enforced granular RBAC using CASL, AuthGuard, and AclGuard across 4 role levels for multi-tenant organizations
Integrated Stripe billing, including plans, checkout, seat management, and invoice UI
Used AI-assisted tools (GitHub Copilot, Cursor, OpenCode) in Agile sprints with CI/CD via GitHub Actions
