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.
