About

I design the system.
I write the code.
I ship the product.

Writing code since 2021, I've shipped products end-to-end across multiple verticals — APIs, backend logic, databases, and the automation around them. I think at the architecture level first: understand the constraint, weigh the tradeoffs, then execute.

Today my focus is the data side of engineering: Python for data work, cloud infrastructure on AWS, and AI-powered workflows.
