I build systems that scale.
Hi, I'm Prakhar Khanna, a Tech Lead with 7+ years of experience building backend systems, distributed architectures and AI-powered engineering solutions.
ABOUT
Backend engineering meets AI.
I'm a Tech Lead focused on building reliable, scalable backend systems. My experience spans high-throughput APIs, distributed systems, payment platforms, data infrastructure and developer tooling.
More recently, I've been exploring local LLMs, AI agents and practical GenAI applications — with a focus on building useful engineering tools rather than AI for the sake of AI.
EXPERIENCE
Building systems at scale.
Backend Engineering
7+ years of experience
