What I'm looking for

I'm looking for global remote opportunities or visa-sponsored relocation where I can build AI-powered, scalable products across mobile, web, backend, and automation while leading cross-functional engineering work.

At Pivotly, I build AI-driven document analysis and invoice-parsing products, including Pivotly PreCon, Parse, and SkyHawk. I also lead the end-to-end migration of SafeLot into a unified Pivotly platform using AI-assisted development tools.

Previously at Silicon Orchard, I led a nine-person cross-functional team delivering connected vehicle, medicine delivery, lottery, mapping, and ballistic-calculator systems across iOS, Android, web, backend, and IoT. My work reduced map-app memory usage by 40% and ballistic-calculator crash rates by more than 50%.

At Solution Cat, I developed and rebuilt five consumer iOS apps in Swift and UIKit. I cut memory usage by 40–80%, reduced crashes by over 90%, and helped grow monthly downloads to 10–11k while increasing subscription revenue more than 10x.

I'm also a two-time ICPC World Finalist, competitive programming trainer, problem setter, and judge, with 2,500+ algorithmic problems solved. I enjoy building scalable systems and am open to global remote opportunities and visa-sponsored relocation.
