Mhd Ulil Abshar

👋 Hey! I’m a backend-focused software engineer building dependable APIs, payment flows, and cloud infrastructure. I work remotely from Indonesia.

I turn product requirements into clear, reliable systems, focusing on backend correctness while still shipping across the full stack.

On the side, I build and maintain open-source projects and write about the engineering decisions behind them.
