Pranav Chandra

Senior Software Engineer (Backend) · Building scalable systems & AI-powered products at LiftOff LLC

The Story So Far

I'm a Senior Software Engineer (Backend) at LiftOff LLC with 5+ years of experience building scalable, production-grade systems that handle millions of daily requests.

I specialise in designing RESTful and GraphQL APIs, integrating large language models (OpenAI, Gemini, Anthropic Claude), and deploying cloud-native applications on AWS and GCP.

My work focuses on backend infrastructure for AI-powered consumer and B2B platforms — data ingestion pipelines, multi-model LLM orchestration, and analytics that turn raw signal into actionable insight at scale.

Outside of work, I build developer tools and AI-powered side projects — exploring where prompt engineering, automation, and product design intersect.
