About

I build systems that make work simpler.

My work combines software engineering, AI, project leadership, and operational problem-solving.

I enjoy taking messy business processes and turning them into software that feels clear, reliable, and useful. At Niimble AI, I focus on AI-assisted recruitment and workflow automation. At Perfect Circle Design, I help lead software development, engineering operations, and client delivery.

My strengths are systems thinking, practical AI implementation, communication, and ownership. I like building products that are polished enough for users, structured enough for teams, and flexible enough to scale.
