Want to actually understand and own your code, instead of relying on black-box magic? This session shows you how to build LLM systems properly, with full control and clear engineering principles.* **​** **Who is leading the session?** ​The session is led by **[Dr. Stelios Sotiriadis](https://www.linkedin.com/in/stelios-sotiriadis)**[,](https://www.linkedin.com/in/stelios-sotiriadis) CEO of **[Warestack](https://www.warestack.com/),** Associate Professor and MSc Programme Director at Birkbeck, University of London, specialising in cloud computing, distributed systems, and AI engineering. ​*Stelios holds a PhD from the University of Derby, completed a postdoctoral fellowship at the University of Toronto, and has worked on industry and research projects with Huawei, IBM, Autodesk, and multiple startups. Since moving to London in 2018, he has been teaching at Birkbeck. In 2021, he founded Warestack, building software for startups around the world.* **​** **What we’ll cover?** ​A hands-on introduction to building software with LLMs using **Python**, **Ollama**, and **LiteLLM**, including: * ​How LLMs, embeddings, and agents work. * ​Calling local models with Ollama or cloud models (OpenAI, Gemini and more). * ​Using LiteLLM for custom prompts and tool-calling. * ​Building simple agents from scratch. * ​Introduction to RAG (Retrieval-Augmented Generation). * ​Working with vector databases (ChromaDB) and vector similarity search library (FAISS). * ​Storing, searching, and retrieving embeddings. * ​Introduction to Streamlit for interactive data apps. * ​End-to-end examples you can run on your own machine. ​This session focuses on theory, fundamentals and real code you can re-use. **​Why LiteLLM?** ​[LiteLLM ](https://docs.litellm.ai/docs/)gives you low-level control to build custom LLM solutions your own way, without a heavy framework like LangChain, so you understand how everything works and design your own architecture. A dedicated **LangChain** session will follow for those who want to go further. **​What are the requirements?** ​Bring a laptop with **Python installed** (Windows, macOS, or Linux), along with Visual Studio Code or a similar IDE, with at least **10GB of free disk space** and **8GB of RAM**. > ​*This space is needed for running local models during the workshop.* > ​*If you don’t have a suitable laptop, please contact Stelios ([stelios.sotiriadis@warestack.com](mailto:stelios.sotiriadis@warestack.com)) before registering.* **​What is the format?** ​A 3-hour live session with: * ​Interactive theory blocks * ​Hands-on coding * ​Step-by-step exercises * ​Small group support * ​Three 10-minute breaks * ​Q&A and class quizzes ​This is a **highly practical, hands-on class** focused on code and building working LLM systems. **​What are the prerequisites?** ​A good understanding of programming with Python is required (basic to intermediate level). I assume you are already comfortable writing Python scripts. **​What comes after?** ​Participants will receive an optional mini capstone project with one-to-one personalised feedback. **​Is it just one session?** ​This is the first session in a new sequence on applied AI, covering agents, RAG systems, vector databases, and production-ready LLM workflows. Later sessions will dive deeper into topics such as embeddings with deep neural networks, LangChain, advanced retrieval, and multi-agent architectures. > ​*You can decide afterwards whether you’d like to join future sessions.* **​How many participants?** ​To keep this interactive, **only 15 spots** are available. Please register as soon as possible.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia

We are recruiting new group leaders for virtual men's groups! Our primary groups are outdoor movement groups, but we are launching virtual groups for the state of Ohio and beyond and the groups will move outside in the spring, creating room for men's groups, women's groups and coed groups all over the country. Read below to learn about our groups and click the links at the bottom to apply. ### **What is an Outdoor Empowerment Group?** Our Outdoor Movement & Community Empowerment Groups are simple, guided experiences designed to help people reconnect with nature, themselves, and others. We combine some form of movement (hike, walk, run, bike, yoga, workout) and meaningful conversation within a simple community circle to create a space where individuals can support each other while prioritizing mental and physical well-being. Whether you’re seeking stress relief, personal growth, or community, our groups offer everyone a unique and welcoming environment. ## **Why Join?** * **Improve Mental & Physical Well-Being** – Movement, nature, and supportive conversations reduce stress and promote balance. * **Feel Less Alone** – Build genuine connections with like-minded people in a safe, welcoming space. * **Gain Clarity & Perspective** – Step outside daily routines and into a space designed for personal growth and reflection. ## **The Ideal Group Leader** The ideal group leader * Has a born-in passion for mental health, movement, connecting with nature and building community. * Has 5 extra hours per week to dedicate to a meaningful cause for at least one year. Yes, you can leave any organization at any time and we can also ask you to leave, but we are building with legacy in mind and we need people who can commit and be ALL IN on this mission to build with us. * Is independently financially stable with the ability to volunteer with no expectation of pay. This is a deeply beautiful journey of service that all participants commit to at Speak Your Mind. * An ability to manage groups with high emotional intelligence and desire for human connection. * An ability to self-motivate and market/promote their group on Facebook and other social platforms. * Nature informed therapy or clinical therapists/psychologists a plus. ## **Our Impact**  Since launching, we have helped thousands find support, connection, and healing through our Outdoor Movement Groups. 100% of participants surveyed have reported: * A noticeable improvement in mental clarity and emotional well-being. * An increase in social connection and a sense of belonging. * Said they would return again. We believe mental health should be accessible, community-driven, and rooted in nature. Join us and take the first step toward a more connected, grounded, and supported version of yourself. ### **Why Our Groups are Donation-Based** Our Outdoor Movement Groups are made possible through a donation-based model. This approach allows us to keep our events accessible to everyone, regardless of financial circumstances, while also ensuring that we can continue expanding our reach. It’s a great way to pay it forward and support the growth of this beautiful mission! Every contribution helps us: * **Cover Essential Costs** – Donations allow us to pay essential legal, marketing, insurance, and admin costs as well as nourish the important people who run the organization. * **Grow Our Mission** – With your support, we can bring these healing experiences to thousands more people in the future and execute our long term plan to expand across the USA, affecting up to 500,000 people per year. By choosing to contribute, you’re not just leading an event—you’re helping build a mental health movement that supports long-term well-being and connection for all during a severe mental health epidemic. ## **Come Join Us!** We’d love to have you be part of this growing community of people prioritizing their mental health, movement, and connection. 🔹 **Visit Our Website to Learn More:** https://speakyourmind.men/joinusoutside 🔹 **Apply Here to Lead Your Own Group!** – https://form.jotform.com/taketimespeakyourmind/sym-group-leader-application 🔹 **Support the mission**: If you resonate with the mission and want to support, feel free to join a group before applying or donate to help us reach our goals to help more people!
