ChicagoRuby @ Chime
333 N Green St, 333 North Green Street, Chicago, IL, USOur Host:
Chime® is a financial technology company that believes core banking services should be helpful, easy, and free. We work with national banks to offer banking products and services that better meet the needs of everyday people. All of our members’ account balances are held at regulated, FDIC-insured banks: The Bancorp Bank, N.A. and Stride Bank, N.A., Members FDIC.† Together, we’re addressing the industry’s fundamental misalignment between what’s good for banks and what’s good for consumers.
We want to profit with our members, not from them. That’s why Chime doesn’t rely on overdraft fees, monthly service fees, or minimum balance requirements. Our business was built with important safeguards at the center, which ensure customer deposits are always safe and accessible.
Today, we offer a member-first banking experience that helps people spend, save, and build credit** — all without unnecessary fees. Members can access their pay up to two days early with direct deposit1, enroll in fee-free overdraft+, grow savings with a high-yield savings account, and build credit with no credit check. With the new Chime Card™2 and Chime Prime, eligible members can also earn 5% cash back§§ on a category of their choice while continuing to build credit safely.Speakers:
🎤 Ifat Ribon (in person) - Fewer Tests, More Confidence
AI can write tests in seconds, but it can't tell you which ones matter (yet). This talk shows how Rails teams can build high-confidence test suites when AI generates most specs, using clear testing principles and practical guidelines to write fewer, better, and more maintainable tests.About Ifat: Ifat is a Principal Architect at LaunchPad Lab in Chicago. She enjoys untangling complex problems, finding the right words for hard things, and helping teams make confident technical decisions. She’s a big fan of good abstractions, long runs along the lakeshore, and finding the signal in the noise.
🎤 Fito von Zastrow (remote) - Defying Gravity: Teaching AI to Write Better Ruby
Code reviews got slower after we introduced AI into our Ruby on Rails monolith. AI-generated code was making the legacy problems worse, not better. Technical debt, fat controllers, tests coupled to implementation. AI reproduced all of it, faster than ever. It's as if legacy code has gravity. In this talk, you’ll learn the concrete techniques we use in production: how to specify what you want, how to provide architectural guidance to agents, and how to use skills to put guardrails in place so feature work incrementally improves the codebase instead of reinforcing legacy patterns. Leave with everything you need to defy Legacy Gravity.About Fito:
Fito von Zastrow is a Staff Software Engineer @ Cisco Meraki. He is a SF Bay Area transplant from Asunción, Paraguay. He enjoys hiking, watching soccer, video games, and pair-programming.🎤 Noel Rappin (in person) - TBA
