About Me

Passionate Engineering Manager

I started as an Android Engineer and worked my way to become an Engineering Manager, which is where I felt most strongly aligned with my strengths. I thoroughly enjoy growing my engineers, building a strong team, fitting projects with the right members, and guiding product and engineering decisions at the leadership level. I strive for consistency and transparency within my team, and I run my team as if they were all close family, being as honest, truthful and helpful where I can be. I'm flexible and adaptable, working with the requirements of upper leadership to deliver what is best and bring up all trade-offs needed to ship. I ultimately care about doing the right things and shipping what is best for the team and the company.

I most recently worked at Robinhood, but have now stepped aside to take a breather and pursue some of my passion projects like Bolt's Adventures, a brain-training game that turns bite-sized challenges and personalized learning into an adventure and more to come
