System blueprint mindset
Reliable APIs, predictable data layers, and deployment practices that keep systems stable while the product evolves.
Senior Backend Engineer & Systems Architect
I build banking-grade backend systems and cloud-ready platforms with a focus on reliability, clean architecture, and sustainable scale.
