Planning to go on parental leave while working in tech? You probably have a ton of questions, and we will do our best to get you answers. Whether you're expecting, currently on leave, planning ahead or wanting to support your teammates, navigating parental leave comes with a lot of new challenges. Technical careers require us to stay up to date and living in Germany adds another layer of bureaucratic hurdles to the mix. To help you feel more prepared, we have selected panelists who've been through it and will share their experiences openly: what worked, what surprised them, and what they wish they'd known. We'll cover the practical and bureaucratic side, the career side, and we'll reserve time for your questions. **🗓️ Agenda** 6:30 Arrival and networking 7:00 Welcome and Intro 7:10 Panel Discussion: Planning Parental Leave in Tech 9:00 Event ends **Panel: Planning Parental Leave in Tech** ● **Saranya Parvathi Ganesan**, Senior Software Engineer @Immoscout24 ● **Sinny Kumari**, Associate Engineering Manager @Red Hat ● **Vanessa Ating**, Senior Frontend Engineer ● Moderated by: **Vaishali Thakkar,** Confidential Computing Expert @SUSE **🍕 Food and Drinks** There will be vegetarian and vegan food and beverages sponsored by our host Bettermile. 🗣️ **About the Panelists** **Saranya** I’m a mother to a four-year-old daughter and currently work as a Senior Software Engineer at ImmoScout24.

Women Techmakers Berlin and SPICED Academy are joining forces to host an evening focused on both building *efficient AI systems* and navigating the real challenges of building a *career in tech*—beyond just learning technical skills. ## Talks Talk 1: Confidence Beyond Skills - What Really Holds Women Back in Tech Careers - by Marina Matveevskaia Many women in tech keep investing in new courses, skills, and certifications, yet still feel stuck or “not ready enough” to take the next career step. In this talk, we will look beyond technical competence and explore the less visible factors that often shape career growth much more strongly — such as self-trust, fear of visibility, internalized expectations, and the emotional impact of burnout or layoffs. I will share common patterns I see in highly capable women and why “just improving skills” is often not the real barrier. Participants will leave with new perspectives and simple reflection tools to better understand what is holding them back and how to move forward in a more sustainable and aligned way. Talk 2: Efficient Agentic Systems - by Jane Waithira Let Classical ML Do the Heavy Lifting, Let Agents Do the Thinking There’s a temptation to throw an LLM at every problem—but the most effective systems take a different approach. This talk explores how to combine deterministic, classical machine learning for predictable tasks with LLM-powered agents for reasoning and decision-making—so you can build systems that are fast, cost-effective, and reliable. ## Speakers **Jane Waithira:** Jane Waithira is an innovative, solution-oriented developer working in AI/ML, currently at SAP in Germany, where she integrates applied AI and GenAI for SAP's own cloud infrastructure. With over five years of experience building production AI systems, Jane has established her skillset in practical applications of ML and GenAI. Her talk will provide attendees with a practical framework for building efficient agentic systems that combine deterministic classical ML with the flexibility of LLM-powered agents. [https://www.linkedin.com/in/waithira-macharia/](https://www.linkedin.com/in/waithira-macharia/) **Marina Matveevskaia:** Marina Matveevskaia is a Professional Identity and Transition Coach working primarily with women in tech and international professionals in Germany. With over 14 years of experience in the IT industry, including leadership roles, she understands the unique pressures and challenges women face in fast-paced, male-dominated environments.

The next **Berlin C++ Meetup** hosted by think-cell takes place on **Tuesday, May 26**. Join us for an evening with the Berlin C++ community! This meetup is a chance to step away from your day to day work, meet other developers, exchange ideas, and have real conversations about modern C++ in a relaxed setting. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- ## **Talk** ### **Contract assertions on virtual functions** *Timur Doumler – Citadel Securities* Contracts assertions were introduced in C++26, but they cannot be applied to virtual functions. To close this gap, we first need to answer the question: how should contracts assertions behave in the presence of inheritance and runtime polymorphism? In this talk, Timur explores why this problem is harder than it looks. He reviews existing approaches from other languages, such as Eiffel, D, and Ada, highlights why they don’t fully translate to C++, and outlines the key design challenges involved. He then presents a concrete proposal for how contract assertions on virtual functions could work in C++, balancing correctness, safety, and usability. Along the way, the talk touches on good API design, the true meaning of the Liskov substitution principle, and how to reason about program correctness. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 📅 **Date & Time:** Tuesday, May 26, 2026 – 18:30–21:30 📍 **Location:** Le Wagon Coding Bootcamp, Rudi-Dutschke-Straße 26, 10969 Berlin 5th floor 🕒 **Agenda** 18:30 – Doors open 19:00 – Talk + Q&A 20:40 – Pizza, Drinks and Networking \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **RSVP now to save your seat!**

Join us this Thursday at Treptower Park for a cozy evening of board games and connection! The mission of Quarter Life Connections is to create spaces for **young people in their twenties** to connect and feel at home in Berlin - especially once the familiar structures of university life stop being there and work life starts. We will start with a quick get-to-know-you round and then split up into smaller groups for games. After up to 2 hours of playing we will close with a check-out-and-stay-in-touch round. The intention is to have fun while getting to know the people around you and form start building connections that will last after the event is over. **Please be on time!** The intro circle sets the tone for the event and is a huge support for making meaningful connections. BRING YOUR OWN GAME - and stuff We will have enough games there to entertain everyone - but maybe you have a game at home you think would be fun to play together? Bring it!

In the previous meetup, we discussed a difficult question: **Will AI replace Scrum Masters and Agile Coaches?** This session builds on that conversation. Instead of focusing on what might disappear, we’ll focus on: **What will become more valuable.** 🧠 **What you’ll learn** We’ll explore the shift from: * Why facilitation and process knowledge are no longer enough * The shift from team-level focus to system-level thinking * How organizational design becomes a key capability * What skills will make you stand out in the coming years Grounded in Org Topologies™, we’ll look at: * Why many roles operate in **output-driven, incomplete setups** * The shift toward **outcome-oriented, complete mandates** * Why organizational design becomes a **core capability** * How AI amplifies this shift rather than causing it 🔑 **Core idea** The future is not about becoming a better Scrum Master. It’s about becoming someone who can: * see the organization as a system * identify structural constraints * redesign how work, learning, and decision-making happen 🎤 **Format** * \~30 min talk * \~30 min Q&A and discussion * \~30+ min Networking 👥 **Who this is for** * Scrum Masters & Agile Coaches seeking their next evolution * People struggling to create impact in their current setup * Leaders interested in system-level change * Anyone thinking about their next career step 💡 **Why join** Many people feel that “something is changing.” This session helps you **name the shift** — and position yourself within it. Btw: This meetup prepares the ground for a special session with the author of *10xOrg* in June.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** https://youtube.com/live/BltmWMH1zG0?feature=share
