Core API makers Long term bets on fundamental components 1. Backbones of web application architecture 2. Investing on “Commerce Primitive” components υϝΠϯΤΩεύʔτ ͦͷڵຯ෼໺Ͱ্Γ٧Ίͨਓͨͪ Photo by Jonny Gios on Unsplash 

SRE We connect dots when distributed system fails • IMOC • Investigate on the “seams” of running system • Collaborate / communicate to drive resolution on “cracks” ෼ࢄγεςϜͷࣦഊύλʔϯʹର͢ΔΤΩεύʔτ Photo purchased from iStock 

Multiplication brings value App dev and SRE • Brings the high velocity project scoping • Distributed system 101 Core API dev and App dev • User and Maker feedback Core API dev and SRE • High-level overview v.s. investing on your core interests 

We are all one team Growth brings specialization and operational e ff i ciency Imagine the dysfunctional feedback loop: • Highly scalable system without the user growth • Growing features without resiliency toolkit • Exponential domain onboarding cost without simple interface to Core API Photo by Kier In Sight on Unsplash 

Chaos Engineer your org Hybrid (bridging) developer can disrupt specialization • Early adaption is quicker and better than an afterthought • It's easily adaptable, since the underlying failure is common across multiple applications • Usually IC has appetite for resiliency toolkits More bridging developers leads to organic early planning: a key to both speed and quality Photo by Olivier Guillard on Unsplash

What’s next? Shopify’s attracting talents from all over the world. • APAC is growing strong! • We embrace fully distributed environment Develop products that changes livelihood of millions of entrepreneurs • Huge potential in the cross border commerce (my former team) Contribute to one of the most powerful web app stack • Ruby, (not only) Rails, MySQL (KateSQL), k8s

Bonus track - How hard was the transition? Shopify managers accepts its “Jungle Gym” 1. Charge your “trust battery” 2. Look for opportunities 3. Probe with the managers
