Senior Backend Engineer · .NET · Cloud Systems
Not a prototype. A production system.
I build the invisible parts people notice only when they fail—APIs, queues, payments, rewards, data, and the infrastructure holding them together.

No mockups.

Engineering philosophy / Soe Thiha
“I don't write code that works. I design systems that survive — traffic spikes, infrastructure failures, 3am incidents, and team turnover. The measure of good infrastructure isn't that it runs. It's that it runs without you.”

The tools are replaceable. The judgement is not.
My primary environment is .NET and AWS. I choose the surrounding services by operational fit, not by attachment to a stack.
