02/About

About me

I build backend-heavy web and mobile platforms, APIs, automation pipelines, and operational systems across e-commerce, ERP, media, and AI-enabled products.

I am at my best when a problem needs both product judgment and systems thinking: designing reliable integrations and event-driven workflows, then owning the path from architecture through testing, observability, CI/CD, and deployment.
