Senior Staff Software Engineer @ Slack

5.0 stars
5.0 (2 reviews)

I've been thriving in the tech industry for 23 years. I'm currently a Senior Staff Engineer at Slack, and a former manager. I'm also a startup founder, technical advisor, speaker, and mentor. When I was a manager and founder, my management philosophy was that I was there to help my direct reports do their best work, to remove roadblocks, provide clarity & direction, to provide wanted guidance, and create a psychologically safe environment for them to thrive. As a mentor, I provide missing perspective, coach on new techniques for success, and cheerlead as needed. I love providing both technical and career guidance, especially deciding if you want to switch from IC to management or vice versa, since I've done both paths.

My ultimate mission is to accelerate & support the growth of underrepresented folks in tech, and to help make the tech industry a truly inclusive place. If you are an engineer from an underrepresented background, I would especially love to connect with you!

On the tech side, I specialize in performant & scaleable web products, mobile apps, and casual games. I’ve worked in nimble startups and large corporations, wearing every hat, from IC to lead to manager to Founder, and I'm driven by a desire to create happy users while leading a highly collaborative, cross- functional team that develops features end-to-end.

I've been a full stack engineer most of my career, and am currently focused on frontend development at Slack. I also have 13 years of mobile engineering under my belt, encompassing iOS, Android, Windows, Symbian, and Palm platforms, which overlap with 16 years of experience in building complex services built on web technologies. I'm comfortable anywhere where I'm making great products for users and where I'm working with a passionate team.

I've managed teams, designed pipelines, built products from scratch, and have always been proud that the products I've worked on have been best-in-class.
