Google Cloud Budapest Meetup is back! Join us on June 17th at the Aliz office in Budapest for an evening of deep-tech insights, practical engineering strategies, and networking with fellow Google Cloud and AI enthusiasts. As AI tools reshape the development landscape, the definition of a "good engineer" is shifting. This meetup isn't about generic AI prompts - it's about the concrete skills and old-school engineering discipline required to build reliable, scalable, AI-native applications. 🎫 The event is free, but seats are limited. **Save yours now! 👇** ⌛ Register here: [https://www.aliz.ai/en/event/google-cloud-budapest-meetup-2026](https://www.aliz.ai/en/event/google-cloud-budapest-meetup-2026) ================= **Talk 1** **Becoming a Context Engineering Professional in Your Domain** by Tamás Imets (AI Solution Architect), Aliz The most underrated skill in the AI era: context engineering. How to structure prompts, design context windows, and become a force multiplier in your technical domain. Practical patterns from the field that turn good engineers into AI-native practitioners. **Talk 2** **The Revenge of the Fundamentals: old-school ideas winning in the AI era** by Máté Czékus (Lead Architect) and Aamna Tayyab (Head of Delivery), Adroit Group The core argument: LLMs accelerate code generation are non-deterministic and inconsistent by default, which makes foundational engineering practices and tooling more important then ever. Teams that skipped the fundamentals, or was still hand rolling checks when AI arrived are paying for it at integration boundaries — it'll be way more harder to guide agent to write compliant and consistent code, and even harder to review the huge amount that was generated. Three fundamental tools doing more work than they get credit for: * JSON Schema — enforcing the contract between modules * TDD — writing the tests before the code * Linters and formatters — static governance that guides the shapeand correctness what the model sometimes misses even with context Máté brings a live demo: one real multi-cloud cost explorer example showing what AI tooling produces by default vs the disciplined version side by side. ================= 📣 Meet the speakers **Tamás Imets** An **AI Solution Architect** at **Aliz** who has been tinkering with tech since age 13 - moving from taking apart toys for robots to founding an AI startup where he led product and engineering. When he’s not building AI-native systems, you’ll find him backpacking through East Asian megacities, playing squash, or experimenting with new musical instruments. **Máté Czékus** He is a **software engineer** at **Adroit Group** who spends his days planning, testing, and refactoring systems while exploring the latest technologies. A passionate specialty coffee enthusiast and functional programming nerd, he believes that if you can build something, you should also be able to deploy and maintain it. **Aamna Tayyab** As **Head of Delivery** at **Adroit Group**, Aamna works at the intersection of product and engineering analyzing requirements, shaping architecture, and turning ambiguous ideas into work teams can actually deliver. Alongside her job, she co-organizes GDG Budapest and stays active in the Google developer community. ================= ☁️ Exclusive Google Cloud meetup in Budapest. 🍕 Cool presentations from experts and a networking opportunity - drink and snacks are on us. 🏎️ Free guarded parking. 🐶 Dog-friendly venue. ⌚️ Arrival from 18:30, presentation starts at 19:00. 🎫 Free, limited seats event, ensure yours by registering: https://www.aliz.ai/en/event/google-cloud-budapest-meetup-2026

==DATE CHANGED== May 27th's event is re-scheduled --> to Jun 17. This month's meetup discusses 3 papers from the ICLR 2026 conference held in April. This won't be as much of a deep dive into one paper, but I'd like to give an overview / some intuition on latest modeling approaches in cell modeling & AI in biology. 1 - [scDFM](https://arxiv.org/abs/2602.07103) \- a **flow matching** model predicting cell transitions in the transcriptomics space as a result of applying perturbations 2 - [TxFM](https://openreview.net/pdf?id=NqZqClqtTK) - **a masked autoencoder style foundation model** trained on a well-curated transcriptomics dataset. Authors demonstrate: how important data quality is in biological models, outweighing sheer scale. 3 - [VCWorld](https://arxiv.org/abs/2512.00306) \- a **world model** approach for virtual cell simulation. A **white-box, cell simulator** approach that **combines structured biological knowledge with LLMs** === ENTRY DETAILS === \- QR code with entry information is available in the "Photos" section of this event page\. \- Gate closes at 18:15 \- no late entries\.

# Integral self-awareness workshops in Budapest Do you ever react more strongly than the moment seems to call for? Do you ever wonder why the people you love most can trigger the biggest reactions? Do you ever say something in the heat of the moment and later wish you had responded differently? Do you ever notice how quickly closeness can turn into tension, defensiveness, or withdrawal? Do you ever get overwhelmed by a tone of voice, a look, or a silence you can’t quite explain? Do you ever feel your body respond before your mind understands what is happening? The integral self-awareness group is a safe and accepting space where you can observe your inner processes and how you relate to others. You can gain insight into recurring patterns and experiment with more conscious, new ways of functioning. The group supports you in letting go of your defensive layers and connecting to yourself and others without judgment. This offers a deeply nourishing experience of acceptance, while also helping you become aware of inner processes that often remain hidden in everyday life. The focus is on experiencing bodily sensations and emotions, often beyond words. The practices are mostly movement-based and require no prior experience. The method is based on integral psychology, associated with Ken Wilber, combining Western psychology with Eastern perspectives to support personal growth and a more loving, present way of being. Join us if, alongside the flow of everyday life, you’d like to connect more deeply with yourself – both your light, vibrant parts and your more shadowed aspects. We work together in a closed, small group over four sessions, in a safe and supportive environment. **Who is this for?** This group is ideal if you haven’t yet participated in a self-awareness process – especially a movement-based one – and would like to try it. You’re also very welcome if you already have experience but are currently looking for a shorter commitment. **What is it about?** We all carry an inner child within us that shapes how we see the world and ourselves. It holds both our resources – spontaneity, curiosity, joy – and the deeper patterns formed through early experiences. This group helps you recognize and reconnect with these parts. **What will you gain?** • A connection with your inner child • Deeper self-connection and emotional awareness • Greater freedom in experiencing your feelings • Acceptance: the experience of being who you are • Insights and experiences that integrate into daily life • A taste of integral self-awareness work The sessions build on each other. At the end of the first session, we ask for your commitment to the full process. **Application** Joining the group is preceded by a short conversation where we get to know each other and decide together whether to work together. If the decision is mutual, your place can be secured with a payment of 7500 HUF, which will be applied to the fee of the final session. The remaining session fees are paid per occasion. Registration here: [https://forms.gle/9zeRqwDq25Nib6JC8](https://forms.gle/9zeRqwDq25Nib6JC8) The events will take place with a minimum of 5 participants.

[Please register via this link if you’d like to join!✨](https://www.sanctuary.hu/service-page/thursday-morning-flow-08-15-en?referral=service_list_widget) This morning Flow class is a light, continuous practice designed to gently awaken and energize the body for the day ahead. We don’t stay in one pose for too long — movement is guided by the breath, creating a steady rhythm and a sense of flow throughout the class. The pace is soft and seamless, helping the mind settle while gradually building warmth, strength, and mobility. The practice supports releasing stiffness, increasing circulation, and creating space for clarity, focus, and a grounded start to the morning. We close the class with soothing stretches after the dynamic sequence, allowing both the body and nervous system to soften and reset before moving into the rest of the day. Each class follows a weekly changing theme, offering a fresh focus and a new experience every time you step onto the mat.

Communication is everything in life You are only as successful as your ability to communicate. \- What if you could confidently talk to anyone? \- What if you had the ability to calmly control every conversation? \- What if you could close that sale\, ask for that date\, make new friends\, repair problematic relationships\, get that raise\, or effortlessly express any idea with confidence? You can! The secret to success relies on your ability or inability to effectively communicate. Attend a free seminar and gain a better ability to communicate.

Grab a drink or some food and get to know each other. This is our first event and we can take it slow. I’d love to meet everyone and hear if there’s anything you like to get out of the group. Looking forward to meeting you all!

This is an in-person meeting. Did you know that unwanted emotions like loneliness, sadness, hopelessness, anger, fear, anxiety, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not chemical imbalance in your brain due to some nebulous chemical reactions by chance. Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. For instance, let's say you are already carrying a huge load on your back, then you cannot take on much more, but, let's say something else happens to you, such as the difficulties from the Pandemic, then the resultant combined weight on you can take you over the edge, kind of like the straw that break the camel's back. When this happens, people's attention usually goes to the straw that was added, but actually the majority of the weight had come from the huge load that were already there, holding a person down and causing a person issues. So how do you remove the huge load that was already there? How do you lighten them up? Is it possible to get rid of them? That is what this meeting will be all about. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics and Scientology Life Improvement Center of Central Ohio.
