Saurabh Negi

I’m a results-driven Backend Software Engineer with 4+ years of experience designing and delivering scalable, high-performance server-side applications. I specialize in Node.js and NestJS microservices, and I focus on clean, maintainable code that delivers measurable impact.

I led an end-to-end migration from PHP (Lumen) to NestJS, refactoring 40+ API endpoints and reducing average API response time by 68%. I also built a custom encrypted security middleware for RESTful API access control, reducing unauthorized API access attempts by ~85%.

I integrate AI/LLM into real workflows using OpenAI GPT-4o, including LLM-based PDF extraction and automated document processing pipelines. This helped enable quote generation for large orders in under 5 seconds—up to a 10x speed improvement—while I also implemented WebSocket real-time order sync and AWS SQS-driven email queues.

Earlier, I developed and maintained ERP and photo management applications using core PHP/MVC and CodeIgniter, and I independently owned the full lifecycle of a full-stack educational platform built with MySQL. I’m energized by technical migrations, performance optimization, and building systems that make teams faster and products better.
