Hi, I'm Harsh 👋

I love building things that work behind the scenes - the kind of systems that make applications fast, reliable, and cost-effective. Over the past 1+ years, I've been deep into serverless architecture, working with Python, FastAPI, and AWS to create solutions that actually solve real problems.

What gets me excited is optimization - like when I managed to cut deployment times from 8 minutes down to under 2 minutes, or when I reduced AWS costs by 59% through smart configurations. There's something satisfying about making systems work better while spending less.

I've had the chance to work on some interesting projects, from building RAG chatbots that improve response accuracy by 40% to creating CLI tools that make developers' lives easier. I'm always curious about new technologies and figuring out how to turn complex requirements into clean, working code.

When I'm not coding, you'll probably find me reading something or exploring to know what's new out there. I'm looking forward to joining a team where I can contribute to meaningful backend infrastructure and continue growing as an engineer.
