What I'm looking for

I am looking for a role that allows me to lead innovative engineering teams, drive product strategy, and foster a collaborative culture focused on delivering high-quality software solutions.

I am a PhD in Computer Science with over 15 years of experience leading high-impact engineering teams across mobile, backend, and web platforms. My career has been marked by a proven track record of launching consumer-scale applications and driving technical vision. I am passionate about creating simple, secure, and reliable products that can scale effectively.

Currently, I serve as a Sr Engineering Manager at HopperInc., where I lead a team of over 20 engineers in delivering travel booking experiences across various platforms. My leadership has been instrumental in navigating complex organizational changes while maintaining app stability for over 5 million monthly active users. I have championed architectural simplification and cross-platform alignment, significantly improving our delivery velocity and team collaboration.

Previously, I held leadership roles at Google and AccuWeather, where I directed mobile app development teams and successfully launched major products under tight deadlines. My expertise in mobile technologies and engineering practices has enabled me to scale engineering velocity and drive strategic initiatives across B2C and B2B product lines.
