What I'm looking for

I'm looking for a company interested in leveraging my varied skills and experience to enhance its product.

At Priority Software, I build and maintain AI-assisted development workflows, using structured prompts and coding agents to support feature delivery, refactoring, and documentation. I’m also working on an AI-native approach to migrating legacy Angular and .NET Framework code to React and .NET 10.

At NCR Voyix, I used AI-assisted coding and refactoring across complex projects, designed software architecture for on-premises solutions, and supervised end-to-end product development. I also initiated R&D projects and worked hands-on with the team on selected projects.

At Kubiya, I took part in front-end development for three projects deployed to several countries. I created responsive, adaptive interfaces and connected them to back-end services using HTTP and sockets.

My personal projects include Carter, a shopping and budget planning app I created from scratch, and Blist, a cross-platform interior mapping solution built with Unity and AR libraries. I’m looking for a company interested in using my varied skills and experience to enhance its product.
