The workshop combined foundational technical concepts about generative AI, agents, models, tools, context, skills, and MCPs with a real operational challenge to connect engineering knowledge with operational expertise. ### Source excerpt Building shared technical understanding so operational expertise can turn AI into practical improvements The post From AI demos to real work: How Engineering and Operations learn side by side appeared first on Building Nubank. ## Clojure/Conj 2026 Will Offer Free Online Streaming to Broaden Access DevFeed: [Clojure/Conj 2026 Will Offer Free Online Streaming to Broaden Access]() Original publisher: [Read original article]() Author: Nubank Editorial Published: 2026-09-11T17:39:44Z Content type: opinion Language: en Sources: [Nubank]() Topics: [Clojure](), [Functional programming](), [coding-community]() Tags: [analytics-engineering](), [clojure](), [data-science-machine-learning](), [developer-community](), [free](), [technical]() ### AI overview This commentary explains how free online streaming for Clojure/Conj 2026 can make technical discussions accessible to developers who cannot travel or afford in-person attendance. The conference will take place from September 30 to October 2 in Charlotte, North Carolina. ### Source excerpt Making technical knowledge more accessible strengthens the entire developer community The post Why this year's Clojure/Conj matters beyond the conference appeared first on Building Nubank. ## NFR Brain: challenging the status quo of risk management with data DevFeed: [NFR Brain: challenging the status quo of risk management with data]() Original publisher: [Read original article]() Author: Nubank Editorial Published: 2026-09-04T14:18:41Z Content type: article Language: en Sources: [Nubank]() Topics: [risk-management](), [data](), [Resilience](), [incident]() Tags: [business](), [complexity](), [data](), [data-analytics](), [data-science-machine-learning](), [management](), [resilience](), [risk](), [risk-management](), [service]() ### AI overview Nubank is building NFR Brain, a platform that combines data, modelling and expert judgement to create a comparable and actionable view of non-financial risk. The article explains how the platform is intended to support clearer, more consistent prioritization across operational failures, customer complaints, third-party dependencies and other risk signals. ### Source excerpt Author : Mayara Zenati At Nubank, we believe the most meaningful problems for customers and for the business rarely come with ready-made answers. That is why we challenge the status quo: not to innovate for innovation's sake, but to remove complexity and build solutions that make important decisions simpler, faster and better. This mindset also [...] The post NFR Brain: challenging the status quo of risk management with data appeared first on Building Nubank. ## How we built a benchmarking framework to horizontally accelerate transaction model research DevFeed: [How we built a benchmarking framework to horizontally accelerate transaction model research]() Original publisher: [Read original article]() Author: Nubank Editorial Published: 2026-09-03T13:53:30Z Content type: article Language: en Sources: [Nubank]() Topics: [benchmarking](), [Framework](), [Transformer](), [data]() Tags: [architectures](), [automated](), [benchmarking](), [data](), [data-science-machine-learning](), [experimentation](), [framework](), [model](), [performance](), [pipelines](), [training]() ### AI overview Nubank built an automated benchmarking framework for horizontally evaluating transformer-based transaction representation models across multiple downstream tasks and trials. The framework made experimentation reproducible and statistically rigorous, helping the team identify improvements that generalize across applications. It increased the team's capacity to run experiments by roughly five times per month while reducing operational overhead. ### Source excerpt The framework that transformed weeks of manual experimentation into automated pipelines for horizontal transaction model research The post How we built a benchmarking framework to horizontally accelerate transaction model research appeared first on Building Nubank.
