A good design isn't just the happy path. Think through retries, duplicate requests, failure boundaries, and recovery before production finds them for you.

LEARNING ✳
HI, I'M HARUN. 👋
I'm a backend engineer who loves finding clarity in complicated systems. My day-to-day curiosity lives somewhere between software architecture, developer experience, and what AI can make possible for engineering teams.
I like turning messy problems into thoughtful solutions, exploring ideas in open source, and sharing what I learn along the way.

OUT LOUD.
Sometimes I ship code. Sometimes I write about what the code taught me.
