Build and run a US self-improvement platform for 3,000+ members end to end: a 500+ endpoint Node.js API and real-time group voice rooms on a Mediasoup SFU (Socket.IO) with sub-200ms latency.

Rebuilt Stripe billing on an idempotent webhook ledger, so a retried event never charges twice.

Moved media to S3 + CloudFront and built a GitHub Actions CI/CD pipeline whose releases health-check and roll themselves back; release cycles under 15 minutes, storage costs down 40%.

Designed a GenAI editorial pipeline publishing 30+ curated stories daily with zero manual review.

Modulus · Frontend Engineer (Intern) Remote · Apr 2025 – Aug 2025

Designed and built the product UI from scratch using React/TypeScript, creating a reusable design system with audience-aware UX decisions that powers 4+ surfaces; supported user-growth trajectory to 1,275+ MAUs.

Integrated 30+ REST endpoints and reduced critical page load by 66% (3.2s to 1.1s) via route-based code splitting and list virtualization, achieving 95+ Lighthouse scores and instrumenting full-funnel PostHog analytics.

Shipped Razorpay (payments) and Cal.com (scheduling) integrations end-to-end with idempotent webhook handlers, successfully processing Rs. 10.8K in platform transactions at 99.9% uptime.
