Clojure is a JVM language that has syntactically similarities to Lisp, full integration with Java and its libraries and focuses on providing a solution to the issue of single machine concurrency. Its small core makes it surprisingly easy for Java developers to pick up and it provides a powerful set of concurrency strategies and data structures designed to make immutable data easy to work with. If you went to Rich Hickey’s talk about creating Clojure you’ll already know this, if not it’s well worth watching the Rich Hickey “Clojure for Java Programmers” video or Stuart Halloway “Radical Simplicity” video .

We are ecstatic to announce the return of the ODSC AI Skills Accelerator to London! Join the local data science and AI community for an exciting, exclusive evening supported by Snowflake. Dive into a cutting-edge technical session led by a Snowflake expert and connect with your peers over complimentary food and drinks. Whether you're a seasoned professional or just starting your AI journey, this is the perfect place to learn, share, and network with fellow innovators. ## Featured Session **Speaker:** Teresa Nascimento, Senior Solutions Engineer at Snowflake [https://www.linkedin.com/in/teresanascimento/](https://www.linkedin.com/in/teresanascimento/) **Talk Title:** *Optimize your Agent’s GPA with Coding Agents* ``` In this talk, we will share how coding agents help developers build high quality agents faster. A key insight from building agents in production is that high quality agents operate with their goals, plans and actions aligned. We introduce the Agent Goal-Plan-Action or Agent GPA framework to capture this insight, which achieved state of the art benchmarks on TRAIL/GAIA with 95% error coverage and 86% error localization. This framework goes beyond examining the agent's final results to assessing the agent's process: Was the goal achieved efficiently? Did the plan make sense? Were the right tools used? Did the agent follow through? Without visibility into these steps, teams risk deploying agents that look reliable but create hidden costs in production. Inaccuracies can waste compute, inflate latency and lead to the wrong business decisions, all of which erode trust at scale. This approach to agent evaluation enables effective and fast optimization with coding agents. We will also show how to use coding agents to automate the process of measuring and improving an Agent's GPA by using agent optimization skills that take advantage of the GPA evaluation framework. By the end, attendees will be able to use coding agents and the GPA framework to identify common agent failures, improve their agent and make it ready for production. ``` Event Details * **Date:** Thursday, July 9th, 2026 * **Time:** 6:00 PM – 8:00 PM BST * **Location:** Snowflake HQ, 3 Crown Place, London EC2A 4EF, UK * **Networking:** Enjoy pizza and refreshments 🍕🥂 included with your attendance!

Itunu Ijila - **What AI Engineers Can Teach Python Developers** Itunu builds AI pipelines. She has shipped agents, automation workflows, and intelligence reporting systems. And she has done most of it without writing a single serious line of Python. In this talk she shares what building production AI systems with tools like n8n taught her about good engineering. Pipeline design, observability, fallback logic, cost awareness, and why these principles matter regardless of the tools you use. She will also show how the architecture behind AI workflows maps directly to the agent patterns Python developers are building today with frameworks like PydanticAI. This is a talk about systems thinking and how good engineering has no syntax. 2. Astha Gupta - **Beyond the Demo: What Nobody Tells You About Shipping AI at Scale** Everyone wants to talk about the model. In enterprise AI delivery, the model is rarely the hard part. Over the last few years Astha has led the delivery of AI platforms for Fortune 500 clients across energy, agriculture, and chemicals. The hardest problems were never algorithmic. They were getting the data in the first place, making sense of it, showing progress before anyone loses faith, and balancing the pressure to move fast with the need to build something that actually scales. This talk covers the full arc of what enterprise AI delivery actually looks like in practice. Getting data from large organisations is often the longest part of the entire project, and the EDA that follows surfaces assumptions that break everything you planned. Showing features early, before the formal UAT four months later, is what keeps projects alive. And the pressure to deliver fast in sprints that have no room for a month long feature is where most technical debt quietly accumulates. The latest chapter of this story is coding agents. They make you faster than ever. But in enterprise codebases where scalability is not optional and understanding what you built is not a luxury, speed without comprehension compounds into something much harder to fix. This is not generic software engineering. The constraints are different, the stakes are higher, and the lessons are hard won. 3. Lightning Talk TBC \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Logistics** * Doors open at **6.30 pm** (get there early as you'll need to sign in with building security). * Talks start at **7:00 pm**, with drinks afterwards from **9:00 pm** at The Banker (EC4).

We're limited by building security on the number of attendees, so please free up your place for your fellow community members.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
