About

I build practical software across product and infrastructure.

From system-level tooling to user-facing apps, I focus on software that performs well and stays clear to use.

My background spans C, Python, Swift, React, and systems work around networking and computer vision. I like projects that sit between product and infrastructure, where the code has to be useful and the UI still matters.

Bridging desktop apps, mobile apps, and backend services

Building real time pipelines for vision and network data

Designing interfaces that stay clear under heavy use

Automating repeat work with scripts and internal tools

Vision

Computer vision in production contexts

From stream data to practical dashboards, the focus is fast iteration and useful output.

Apps

Desktop and Android workflow tooling

Internal software built to support operations, automation, and reliable day-to-day execution.

Interface

Motion and hierarchy used with intent

Animation is used to guide attention and improve pacing, not to distract from the product.

Security

Network monitoring and hardening work

Practical security tasks across monitoring, prevention, troubleshooting, and infrastructure updates.

Experience

Roles across product delivery, tooling, and security.

Current and recent work focused on desktop, Android, networking, and computer vision.
