Saurabh Kumar

I've delivered production backend solutions for logistics and education platforms at SIEC, Gurugram, building RESTful APIs with Node.js and Express.js for Gradlynk and The Sieceducation.com.

I design MongoDB schemas, aggregation pipelines for real-time reporting, and integrations for payment gateways, SMS, and notification APIs. My Node.js work applies async JavaScript, middleware architecture, and JWT-based authentication.

Over two years in Laravel development, I've delivered six full-scale applications across hotels, travel, events, cabs, nutrition, and wellness. I architected MVC backends with Eloquent ORM, complex database relationships, and optimized MySQL queries.

I've built secure Laravel Passport and Sanctum authentication with role-based access control and integrated more than 10 third-party APIs while maintaining 99%+ uptime. I work closely with frontend and QA teams in Agile sprints to meet release deadlines.
