Speakers
Stephen Margheim
Hey, I’m Stephen. I’m an American expat living in Berlin with my wife and two dogs. I am a contributor to Rails and the sqlite3-ruby gem as well as the maintainer of a handful of gems aimed at making Ruby and Rails the absolute best platforms in the world to run SQLite projects.
Maciej Rząsa
Software engineer with 10+ years of experience. He started applications from scratch, dealt with legacy, and extracted services from a monolith and led teams. Strong proponent of diving deep into black boxes, he focuses on distributed systems and database internals. Has a strange hobby of writing regular expressions by hand and discussing their performance. Knowledge-sharing advocate: after work, he's a university instructor, public speaker and meetup organiser. Bookworm, hiker and history buff (ask him about Napoleon!).
Andrei Kaleshka
With over 15 years of experience using Ruby on Rails, I am a seasoned software engineer and a published author. I have written the book "Rake Task Management Essentials", which covers the latest techniques in building, testing, and debugging rake tasks to solve real-world automation challenges. I have also worked with well-established companies like TopTal and Hubstaff, as well as successful startups like ActivePlatfrorm, WorshipOnline, Fisikal, and Costa del Home.

In 2014, I founded WideFix, a software development agency that specializes in Ruby on Rails and React. My expertise lies in thorough analysis and delivering robust technical solutions to businesses. I lead a team of talented developers who share my passion for creating high-quality applications that meet the needs and expectations of our clients. My mission is to help entrepreneurs and organizations bring their vision to life with our top-notch development services.

In 2021, I built an allowance tracker for my kid that I still use myself and published for everyone that's published at get.budgetingkid.com.
Radoslav Stankov
Full stack developer with 20+ years of experience. He is currently the CTO and Co-Founder at Angry Building. Previously was Head of Engineering at Product Hunt.
Caio Almeida
Caio is a senior software engineer from Salvador, Brazil, with over 15 years of expertise in working with Ruby on Rails (since 2008) and JavaScript (since 2005). He has been working for more than 10 years in the United States after working for companies also from Brazil, Canada, and the UK. He currently works at Meedan, an organization based in San Francisco, California, that specializes in developing open-source tools for fact-checking. Caio holds bachelor's and master's degrees in Computer Science, certification as a Ruby Programmer, and has shared his insights at various conferences such as RubyConf Portugal, Rubyfuza (in South Africa), Mexico on Rails (in Mexico), RailsConf Brazil, and others. In his spare time, one can find him biking or at a rock concert.
Dávid Halász
Principal Software Engineer at Red Hat by day, with 10+ years experience in Ruby. Researcher at Masaryk University by night, working on his PhD thesis about Trust, Safety and Autonomous Ecosystems. Currently living in Brno, Czech Republic.
Paweł Pokrywka
In a world celebrating experts, I'm far from being one. I just like computers and solving problems. I try to do what needs to be done while exercising my creativity and experiencing the ups and downs of the process. I prefer to use Unix, Ruby, and Open Source solutions. My curiosity led me to learn about security, privacy, cryptography, operating systems, networking, blockchains, and web-related fields. Privately, I enjoy contemplating classical paintings and sculptures. In my daily life, I try to apply principles of non-violent communication. I like to think about why people do what they do. I'm not sure what amazes me more: hard-core technology challenges or complexities of human nature.
Andrei Bondarev
Andrei has been a software engineering professional for almost 13 years. Among many others he’s been fortunate to make his impact at Spree Commerce (Acquired by First Data), WeddingWire (merged with The Knot), FiscalNote (IPO), National Public Radio, and USA Today. He currently runs a software dev firm, and serves as an Architect/Engineering Manager/Fractional CTO on the client projects. In his free time he enjoys playing tennis and going on long runs while listening to podcasts.
Erwin Kroon
Erwin is a Full Stack developer currently working as a Software Engineer at GitHub on the Issues Platform team. He spends most of his time in Ruby/Rails code. In his free time he walks dogs.
Ivan Nemytchenko
Ivan is a serial CTO of early-stage startups. He is building and leading small teams of full-stack developers to help startups achieve their goals without compromising speed of development and quality. Ex-GitLab. Author of a book about complexity management "Painless Rails" and Modern Make handbook.
Bartosz Blimke
Bartosz is the author and maintainer of WebMock, an iconic gem that has become a standard in Ruby for stubbing and setting expectations on HTTP requests. He is a seasoned software developer, with over 21 years in the game, an ex-CTO, and a consultant who's had a long-term relationship with Ruby for the past 17 years - sorry C++ and Java, it's serious! He's all about crafting clean, maintainable code. When he's not transforming ideas into code, he's a dad of two, who somehow also finds time to pursue his love for diving and specialty coffee brewing. He's all about exploring - whether it's underwater or in a coffee cup.
