Освен нашите въпроси, всеки от присъстващите може да зададе и свои и да се включи в разговора. През месец май очаквайте Matthias Zeitler, сериен предприемач Matthias Zeitler builds and operates long-term residential environments where people live and work — with a focus on making them economically and structurally viable over time, not just attractive in the short term. He has lived and worked internationally and is now based in Bulgaria, where he leads large-scale real estate and community projects. As chairman and operational lead of Coliving Semkovo, he is responsible for the redevelopment of a \~17,000 m² former hotel into a residential community with more than 200 units. His work centers on turning underused or mispositioned assets into functioning places — designing ownership structures, operational models, and governance that hold up under real conditions. He typically leads projects through uncertainty and then steps back once they are stable. Matthias was co-founder of Coworking Bansko, contributing to the town’s emergence as a global remote work hub, and founder of Bansko Nomad Fest, which he later exited. His earlier career includes senior product and technology leadership roles in international, enterprise-scale environments. His current and upcoming projects include Thracian Views, a residential redevelopment near Sofia, and Nomad Pioneers — an initiative exploring how new remote-work ecosystems form in emerging locations. His perspective is pragmatic: less about vision and positioning, more about what actually works over time — financially, operationally, and socially.

Please join us on May 20th for an amazing co-hosted practical meetup with the Data Science Society! ## What can you expect? ​This hands-on workshop explores how modern AI tools are changing everyday software engineering. Participants will see practical, real-world examples of how developers use tools like Kiro, Claude Code, Windsurf, and Cursor to write, debug, refactor, and understand code more efficiently. ​The session focuses on concrete use cases - speeding up feature development, improving code quality, navigating large codebases, and integrating AI into existing development cycles. It will give attendees a clear view of what “AI-augmented development” looks like in practice. ## ​Who will present? ​We have 4 speakers : * ​Rosen Krumov * ​Borislava Bagaliyska * ​Petar Ivanov * ​Viktor Botev ​Soon we will announce a bit more about the concrete expertize and focus of each of them! # ​Official partner ​For this meet-up our official partner is [iris.ai](https://iris.ai/?utm_source=luma). ​[Iris.ai](https://iris.ai/?utm_source=luma) is the AI Development and Operation Platform for building secure, high-performance Agentic RAG systems. ​Event is free but registration is mandatory: https://luma.com/bz9lg7aq

4 години споделяме знание! Създаваме сигурност. Празнуваме заедно! Настъпи момент да отпразнуваме заедно **4-тата** **ГОДИШНИНА на Cyber Security Talks Bulgaria**. Този път без домакин и по много по-различен начин. Заповядайте на нашето парти в Art Bar 158 на **20.05**. Вече 4 години създаваме общност, споделяме опит, мнение и научени уроци, защото така вярваме, че ще постигнем по-сигурно Киберпространство за всички нас. Стъпвайки отново фраза от добре познатия ни сериал „Бар Наздраве“ : „Where everybody knows your name“, бихме казали, че Cyber Security Talks Bulgaria се утвърди като място, където всеки е добре дошъл. На 20 май това място е „Art Bar 158” (ул. „Княз Борис I“ 158). Подготвили сме една по-различна от обичайното програма, но ще я разкриваме постепенно. Както казваше един знаменит българин „Часът и мястото на срещата са известни“ – Часът е обичайният, дата - нестандартна, мястото – различни от всяко до момента. **Всеки гост на нашето парти ще получи подарък. Първото питие е от нас.** Ела на едно по-различно събитие с quiz, жива музика и приятни моменти. Бъди част от общността!

We’re getting together at McCarthy’s for a different kind of evening—one cantered on the journeys that brought us to Sofia and the local roots that keep us here. Whether you’re a local, looking for a social drink after work or you just landed yesterday from afar, come grab a drink and help us bridge the gap between the expat and local scenes.

**ProductTank NoVA is back!** After a brief hiatus, we are relaunching the chapter with a format that cuts out the fluff and gets straight to the reality of building. Every product feed is flooded with AI hype right now, but what does it actually look like on the ground? Instead of a polished keynote, we are hosting **0 to 1 with AI: Real Product Talks**—a "Show & Tell" featuring 3–4 lightning talks focused on the intersection of AI and product. The framing for the talks is simple: *"Here is what I'm building, and here is what I'm stuck on."* We want to look at the messy, 0-to-1 reality of integrating AI into your workflows and products. *(Want to share what you are working on? Reach out! The bar is low-pressure, just 10–12 minutes to talk about a real AI problem you are trying to solve.)* **Agenda:** * **5:30 PM - 6:00 PM:** Doors open, networking, & name tags * **6:00 PM - 6:10 PM:** Welcome + Chapter Relaunch Intro * **6:10 PM - 7:30 PM:** Lightning Talks (Three 12-min talks + 5 mins Q&A each, with a 5-min stretch break) * **7:30 PM - 8:00 PM:** Open networking * **8:00 PM:** Soft close **Location & Logistics:** Herndon Fortnightly Library (Extended Hours Meeting Room) 768 Center St, Herndon, VA 20170 * **Parking:** We'll meet at the library, located just behind the Herndon Municipal Center. There is plenty of free public parking available around the municipal center. * **Metro & Bus:** Take the Silver Line to Herndon Metro Station, then connect via Fairfax Connector Route 921 or 950 to Historic Downtown Herndon. * **Driving (via VA-267/Dulles Toll Rd):** Take Exit 10 North (Centreville Rd, which becomes Elden St). Turn left onto Station St or Lynn St. * **Driving (via VA-286/Fairfax Co Pkwy):** Take the Elden St West exit. Turn right onto Lynn St. Looking forward to seeing everyone again and getting back to building!

Join us for another optional writing session! Feel free to bring a project you're already working on or start something new with us. If anything interesting comes up while you're writing, you can share it with the group, but no pressure!

Qamaria Yemeni Coffee is authentic, spacious, has a helpful staff, and I like their espresso. If you try this place on your own, they’re open early and late. This spot has been recommended a couple times and I think it’ll make a great stop on our journey. Come out Saturday morning for a relaxed convo. (Please keep your RSVP updated if you know you won't be able to attend, so others who can join have the opportunity to. No discussions on politics, religion or potentially controversial topics. We're here to relax and have fun. Just be respectful and we'll be alright. Pay your own way, and enjoy!)

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)

You must read the following NVHC Sign-in Sheet Statement/Liability Disclaimer, [https://nvhc.com/signin.pdf](https://nvhc.com/signin.pdf) and then answer the question that you will see when you RSVP with "I accept" to be permitted on the hike.
