I’m Chirag, a Senior Engineering Manager at Atlassian. I write about the things I actually use at work - system design, databases, cloud infrastructure - and the money stuff I wish someone had explained to me earlier in my career.

I’ve spent over a decade building and scaling software systems - from payment platforms to real-time data pipelines - across startups and product companies before landing at Atlassian, where I lead teams building collaboration tools used by millions.

This site is where I put everything I’ve learned along the way.

What you’ll find here

Tech blog - System design breakdowns, programming deep dives, developer tools, and engineering career lessons. Real code, real architectures, not theoretical hand-waving.

Finance guides - Investing strategies, mutual fund analysis, tax planning, and money management for salaried professionals in India. Every post includes actual math and real numbers.

Developer tools - Free browser-based utilities like a JSON formatter, regex tester, JWT decoder, and more. Everything runs locally - no data leaves your machine.

Finance calculators - SIP, EMI, HRA, emergency fund, and other calculators built for Indian professionals. Again, fully client-side.

DSA prep - Curated problems with clean explanations for coding interview preparation.
