Hi, I'm Lakshay Mahajan

Backend Engineer

I build reusable backend systems with Node.js/Express, MongoDB, and AWS SNS/SQS/Lambda. My centralized authentication service powers multiple live apps, with JWT (RS256), Google OAuth, rate limiting, and async email notifications.

About Me

I’m Lakshay, a backend developer focused on building authentication systems and event-driven service. My auth service uses Node.js/Express, MongoDB, JWT (RS256), Google OAuth, and AWS SNS→SQS→Lambda for background email notifications.

I prioritize clean architecture and real deployments.
