  • TypedDict, Dataclasses and Pydantic in action
Karolina Griciunė

I started my career as a data scientist 7 years ago. Organisation I was working in was making first steps towards data science and I was one of a few ones to make those steps. I spent more than 3 years leading data science team and mentoring people who wanted to become data scientists. Currently I am working as a Head of Data at SME Bank.

  • Data-driven products: from zero to hero
Kostas Jakeliūnas

I like everything from hairy backends to cognitive neuroscience. Been part of this weird world of professional software engineering for a while.

I remember an interesting defining moment in 2013 in Munich where working as a GSoC intern at Tor, I overheard a conversation where a person from Syria was sharing how they rely on certain software to make sure they're not persecuted by their government which actively oppresses activists. They were like, "yeah and you could improve usability in this place, that would be great, but otherwise yeah, appreciate being alive, you know."

Tech-wise, I like both low-level security-focused engineering as well as HoTT. I guess I can thank my background in Computer Science and Philosophy for my pretentious eclectic tastes. To paraphrase my personal hero Moxie Marlinspike, I'm both fascinated and scared by technology and what it can do.

I currently lead software architecture at ZealiD where, originally, I work as a Software Architect.

During school years I participated in mathematics and programming contests with good results.
Then worked as a programmer for 3 years in a blockchain startup (not scam).
Moved to Vilnius and did intensive spiritual practice (Falun Dafa) for one year.
Have been working as a programmer for 1.5 years at ZealiD.
Now I believe technology is harming humans and we should all stop programming.

  • A new framework for testing
Peter Vidos

Peter is the CEO & Co-Founder of Vizzu.

His primary focus is understanding how Vizzu's innovative approach to data visualization can be put to good use. Listening to people complaining about their current hurdles with building charts and presenting them is his main obsession, next to figuring out how to help data professionals utilize the power of animation in dataviz.

Peter has been involved with digital product development for over 15 years. Earlier products/projects he worked on cover mobile app testing, online analytics, data visualization, decision support, e-learning, educational administration & social. Still, building a selfie teleport just for fun is what he likes to boast about when asked about previous experiences.
