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.

How will AI impact the arts? What are the ethics of parasocial relationships? Who deserves to be cancelled? Where are the limits of language? At this event, we'll explore detailed scenarios where these ethical dilemmas play out. We’ll rotate in small groups between four different scenarios. Discuss, share, and hear how others think. This is for anyone who enjoys: * Thought-provoking conversations * Meeting new people in small groups * Practical philosophy 📅 Date: Tuesday, 19 May 🕖 Time: Event begins at 19:15 📍 Location: The Steps (upstairs) 🎟️ Price: Free NOTE: There is NO LIMIT on the number of participants.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
