01. About Me

Hello! I'm Abhay, a backend specialist who loves building things that live on the internet. My journey in software development started with a curiosity about how data flows across the web, which led me to specialize in high-performance backend architectures.

Fast-forward to today, and I've had the privilege of working at a cybersecurity firm like FireCompass, where I focused on reducing latency and building robust data pipelines.

My main focus these days is building scalable, real-time applications that provide seamless experiences for users worldwide. I thrive on solving complex distributed system problems and optimizing every millisecond of API response time.
