Work Experience

Full-Stack Engineer

Divridh

Jan 2025 - Present
  • Owned end-to-end product development: backend API design, React frontend, AWS EC2 deployment, and post-launch maintenance — all independently.
  • Designed 20+ RESTful APIs for user auth, project management, comment threads, creator dashboards, and payment processing.
  • Reduced API response times by ~30% (approx. 400ms → 280ms) via MongoDB query optimisation, route restructuring, and eliminating redundant DB calls.
  • Cut media delivery time by ~40% using Redis caching for images and high-frequency read endpoints.
  • Integrated Cashfree payment gateway end-to-end: checkout UI, server-side order creation, webhook verification (HMAC-SHA256), and idempotent event handling.
  • Built Google OAuth 2.0 authentication with secure sessions, protected route middleware, and role-based access (creator vs contributor).
  • Deployed on AWS EC2 with Nginx reverse proxy, PM2 cluster mode, and environment-based config management — zero unplanned downtime since launch.

Projects

Adobe Express Formula Inserter Add-on

ReactViteKaTeXPubChem API
  • Built and shipped an Adobe Express Add-on rendering math and chemistry formulas as exportable images — compatible with Adobe SDK sandbox constraints.
  • Integrated PubChem REST API for real-time compound resolution and KaTeX for LaTeX-to-image rendering within an iframe-constrained environment.
