OCaml Programming

​​*A 'Humans in the Loop' community event with Elastic, Uptime Labs & PagerDuty in collaboration with OOPS!* ​​We’re taking over the Greenwich Design District for an evening dedicated to the unsung heroes of the stack: **The Humans in the Loop.** AI adoption offers a range of benefits, but while our systems get more complex, the role of the human in incident response has never been more critical. ​Come trade your real-time operations stories, share your best 'oops' moments, and learn how to keep the 'human' in your high-availability architecture. 📅 **Date and Time:** Monday, June 1, from 6:00-9:00 PM 📍 **Location:** Design District Address: 19 Soames Walk, London SE10 0AX, UK ​​**What to expect:** * ​​🎤 **Lightning Keynotes** \- short\, sharp and stimulating\, local experts share their takes\. * ​​🍻 **Sip & Savour:** Delicious pizza and refreshing drinks to fuel the conversation. * ​​🤝 **The OOPs Group:** Connect with the outage ops + incident response community, because misery loves company, but resilience loves a party. ​🧠 **Talks** **Many Humans in Many Loops** by **Carly Richmond**, Developer Advocate Lead (Elastic) *Human in the Loop, or HITL, provides us the ability to validate AI output using friendly and knowledgeable humans. But is that the only human loop in AI incident management systems? Join Carly as she covers other human loops, including reinforcement learning with feedback and context engineering, and how loops with a low threshold encourage alert fatigue.* **Incident Response Reimagined: Accelerating Resolution with AI Agents** by **Daniel Afonso**, Senior Developer Advocate (PagerDuty) *Learn how PagerDuty is leveraging Agentic AI to transform the incident lifecycle from reactive firefighting to proactive prevention.* *Daniel demonstrates how new tools like the SRE Agent and Scribe Agent assist engineers during high-pressure outages by autonomously triaging alerts, querying logs in tools like Grafana, and transcribing context directly into incident channels.* *Beyond immediate response, this demo highlights a "shift left" strategy using the new PagerDuty MCP server and Claude Code plugin, which allows developers to assess the risk of code changes against historical incident data before deployment, ultimately aiming to reduce the frequency of on-call.* ✍️ ​​**RSVP now before we reach capacity**

Hi folks! Welcome to our June Cloud Native London meetup! Join us to hear from our two fantastic speakers and network with your fellow techies over pizza and drinks, or alternatively chat and following along on Youtube or LinkedIn! 6:00 Pizza and drinks 6:30 Welcome 6:45 Universal Mesh: Connect and Secure Everything (Mark Boddington, HAProxy Technologies) 7:15 Building Abstractions That Matter: A Developer Platform on Kubernetes (Chaamini Mangaleswaran, WSO2) 7:45 Wrap up See you there! Cheryl (@oicheryl) **Universal Mesh: Connect and Secure Everything (Mark Boddington, HAProxy Technologies)** Managing connectivity across diverse business units, clouds, locations, and partners is a complex challenge for large organizations. Traditional solutions like VPNs and firewalls provide network-level connectivity, while Service Mesh offers application-aware traffic management for cloud-native environments – but there’s a huge difference in how these connectivity models are managed, secured, and observed. Universal Mesh bridges this gap with a unified interconnectivity model – delivering the benefits of Service Mesh in a resource-efficient model that works across your entire infrastructure. Universal Mesh brings together North-South and East-West communication in a consistent pattern to connect every cloud, app, and service. Join us to discover how Universal Mesh simplifies connectivity management, unifies security and governance, and provides consistent control over traffic flows—regardless of where your applications run or how they’re built. **Building Abstractions That Matter: A Developer Platform on Kubernetes (Chaamini Mangaleswaran, WSO2)** Kubernetes provides powerful building blocks, but turning those blocks into a usable developer platform is hard. Many platform teams end up assembling CI pipelines, deployment tools, portals, and monitoring systems, only to pass the resulting complexity on to developers.In this talk, I’ll share the thinking behind OpenChoreo, an open-source, modular platform designed to sit on top of Kubernetes and make it easier for developers to build and run software without needing to understand everything underneath. The key idea is simple: introduce the right abstractions, so developers can focus on shipping features while platform teams retain control and consistency.In this talk we will discuss practical examples of what to hide, what to expose, and how to avoid turning Kubernetes itself into a developer-facing interface. If you’re building or struggling with an internal developer platform, this talk is for you. *Check out [https://www.oicheryl.com/cloudnativelondon](https://www.oicheryl.com/cloudnativelondon) if you're interested in speaking or sponsoring.*

**We're back at Salisbury House for our summer London Airflow Meetup! Join fellow members of the data engineering community for an evening of engaging talks, great food and drinks, and exclusive swag!** **PRESENTATIONS** ***Talk #1: The Orchestration Layer: A Blueprint for Scaling Dynamic DAGs with Integrated Data Quality Gates*** * **Speaker**: [Vasudev Maduri](https://www.linkedin.com/in/vasudevmaduri/), Staff Data Engineer, Admiral Group Plc Ensuring high-quality data, accuracy, completeness, and schema validity is essential for building data trust. However, scaling data quality checks across diverse datasets often leads to duplicated boilerplate Python code, human error, and a massive bottleneck for Data Engineering teams. In this talk, we’ll explore how to shift data quality from a backlog of tech debt into an automated, self-serve developer experience directly tied to Airflow. We will demonstrate how to build a multi-faceted data observability framework that empowers end-user teams to define their own DQ rules without writing any Python code. By hiding complex Airflow code, users simply select their parameters—YAML configurations that instantly translate into fully dynamic, end-to-end DAGs, including in-flight data quality gates. The core of this session focuses on the technical implementation of integrated DQ checks that live directly *inside* the generated pipelines. You’ll learn how this metadata-driven approach enables a "shift-left" strategy for data observability, automatically enforcing data contracts and routing alerts without manual engineering intervention. ***Talk #2: Self-healing Data Pipelines in Airflow*** * **Speaker**: [Nilesh Khandalkar](https://www.linkedin.com/in/nileshskhandalkar/), Senior Manager, Capgemini Modern data pipelines remain largely reactive—failures trigger alerts, manual retries, and ongoing operational overhead for engineering teams. As systems scale, this approach introduces fragility, delays, and growing complexity in maintaining reliable workflows. This session explores how to design self-healing data pipelines in Airflow using practical patterns such as intelligent retries, conditional branching, and targeted recovery mechanisms. Real-world failure scenarios are used to illustrate how pipelines can detect issues, trigger remediation steps, and resume execution without full restarts or human intervention. The session also looks ahead to how AI-assisted anomaly detection can further enhance these systems by identifying unexpected patterns and enabling more proactive, resilient data workflows. ***Talk #3: What We Got Right (and Wrong) Building a 50-Source Data Platform on Airflow*** * **Speaker**: [Arnaud Caldow](https://www.linkedin.com/in/arnaud-caldow-384423142/), Senior Data Engineer at Collibra Collibra helps enterprises govern their data, but how does Collibra's own data team manage the data that powers the business? The answer is an Airflow-based platform that stitches together dlt, dbt, Kubernetes and Collibra's own product for governance -- all orchestrated through 87 DAGs serving 12 business domains. This talk traces a data point's journey through the stack: from API extraction via dlt pipelines running inside KubernetesPodOperator pods, through a layered dbt architecture where platform engineers standardize data and analysts build business models on top, into analytics outputs that serve multiple business teams, and finally back into Collibra Data Governance via reverse-ETL integration DAGs. Along the way, I'll share the patterns that emerged from operating this at scale: how we evolved from one-off custom pipelines to a reproducible framework that's documented well enough for AI subagents (or a new hire) to generate models from scratch, how our own Pod Operators let us test feature branches on shared environments, and how we're leveraging that same mechanism to migrate from Redshift to BigQuery (and from Airflow 2 to Airflow 3) without downtime. Behind the scenes, a 1Password-backed pipeline diffs credential hashes nightly, catching rotations before they break a DAG. **AGENDA** * **5:30-6 PM:** Arrivals, networking, food & drinks * **6-7:45PM:** Presentations * **7:45-8PM:** Networking
