With 5+ years of experience building resilient systems at the Netflix scale, Lorin joins the show to chat about his favorite incident story, the path that led him to doing chaos engineering (and later away from it), and advocating for a dedicated analyst to talk to people after an incident. Throughout the conversation, Lorin shares his philosophy and tips on how to learn from incidents, what engineers can gain from writing better, and why some metrics may not be as useful as you think.

Having led 100+ ML projects at Insight and built ML systems at Stripe scale, Emmanuel joins the show to chat about how to build useful ML products and what happens next when the model is in production. Throughout the conversation, Manu shares stories and advice on topics like the common mistakes people make when starting a new ML project, what's similar and different about the lifecycle of ML systems compared to traditional software, and writing a technical book.

Todd is a Sr Director of Engineering at Google where he leads Site Reliability Engineering teams for Machine Learning. Having recently presented on how ML breaks in production, by examining more than a decade of outage postmortems at Google, Todd joins the show to chat about why many ways that ML systems break in production have nothing to do with ML, what's different about engineering reliable systems for ML, vs traditional software (and the many ways that they are similar), what he looks for when hiring ML SREs, and more.

Evan Estola (https://twitter.com/estola) is a Director of Engineering at Flatiron Health where he's leading software engineering teams focused on building Machine Learning products. Throughout this episode, Evan shares various stories when recommendation systems didn't work as expected, like this one time when members saw mathematically worst recommendations for meetups near them. He also shares why Schenectady, NY pops up on some lists of most popular cities and the story behind the Wall Street Journal article titled 'Orbitz steers Mac users to pricier hotels'. We also discuss skills Evan looks for when hiring ML engineers, how to give constructive feedback, filter bubbles and much more.

Uma is a VP of Engineering at Render. In this episode, she shared with us her insights on how to successfully manage infrastructure migrations. We discussed the importance of communicating the "why" behind a migration, identifying success metrics, creating a culture where migrations are identified as highly impactful projects and much more. Uma also shared stories where parts of a migration didn't go as planned, how the team fixed the issue and the kind of engineers she thinks would make good tech leads for these projects.

We had a great time speaking with Uma! Our major focus in this episode was large scale infrastructure migrations and Uma shared many insights on how to manage them successfully. We discussed the importance of communicating the "why" behind a migration, identifying success metrics, creating a culture where migrations are identified as highly impactful projects and much more. Uma also shared stories where parts of a migration didn't go as planned, how the team fixed the issue and the kind of engineers she thinks would make good tech leads for these projects. There's a lot to learn from Uma's experience. Please enjoy this highly educational conversation with Uma Chingunde!

We had a lot of fun speaking with Charity in this lively conversation! We learned about her journey from being an engineer to co-founding Honeycomb, what it was like being on-call when she was only 17, and staying calm during production incidents. We talked about various production outages throughout the episode and our favorite involved driving to a datacenter to flip a DB switch. Charity also shares what it takes to build an awesome engineering culture, the engineer/manager pendulum, and qualities Charity looks for when hiring senior engineers.

Tammy Bryant Butow is a Principal SRE at Gremlin where she works on Chaos Engineering. In this episode, we discuss how her curiosity led her to the world of infrastructure engineering, an outage from her early days where a core switch took down half the datacenter, her experience running a disaster recovery test and how it taught her about the importance of injecting failures into a system to make it more resilient. We also touch on advanced failure injection techniques, how chaos engineering is evolving and how extreme sports help Tammy keep calm under pressure. Lastly, Tammy has some great advice for teams looking to get started with chaos engineering.
