I am a fullstack software engineer, frontend leaning. I solve complex technical problems and help shape both product and architecture. I know how to build and deploy scalable systems. I enjoy improving user experience on all devices. I like the challenge of integrating new technologies into existing infrastructures. As a collaborative team player, I can provide technical guidance and leadership to engineers across the organization. I hold high expectations of both myself and my team.
