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.

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!

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? 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: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.

How to be a Better Communicator Communication is everything in life Sunday, 23 February at 2pm. 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.
