PyCon Lithuania 2026

Aidis Stukas is a Python Software Foundation Fellow, CTO at EnforceShield, and the organizer of PyCon Lithuania. With a philosophy background and over a decade in Python, he explores machine learning and agent-based modelling from his home base in Kaunas.

I am a software professional and solution architect with 30+ years of experience in IT. I have been developing in Python since 2010. Prior to that, I worked extensively with ASM, C/C++, C#, etc.
I have been actively using AI in software development since 2023. At present, up to 80% of my production code is written with the help of AI agents. My main focus is on applying AI-assisted development practices in a disciplined, engineering-driven way.
I am an AI Ambassador at EPAM, where I promote practical adoption of AI tools and workflows in everyday software engineering.

After 18 years in the data and analytics industry - spanning roles from banking strategy at Nordea to Head of Data at Luminor and Girteka - I made a conscious decision to step out of the corporate world.

Why? Because my skillset doesn't fit a standard job description.

I am a true Generalist in a world that often tries to specialize. I don’t just analyze data; I engineer the pipelines, write the code, design the UI, and map the business strategy. I realized that my ability to manage the entire data journey - from raw SQL to the final user experience - was best utilized in building my own solutions rather than managing narrow slices of corporate infrastructure.

Today, I am fully dedicated to Product Development. I build software where data isn't just a byproduct; it is the core engine.

My flagship product, Scoris, is Lithuania's premier open business data aggregator, built on the belief that public data should be accessible and actionable. I also created Oriux, a weather app designed for precision. Few other massive products about to launch soon.

I bridge the gap between complex data engineering and tangible business value. I am no longer just advising on strategy; I am executing it, line by line and database by database.

With over 20 years in the trenches of engineering, he now focuses on the messy reality of getting agentic systems to work in production.

Hi there, I'm Nino!
An Italian-Finnish theoretical physicist turned into a Software Engineer for a living.

My relentless curiosity drives me to continuously explore new languages and frameworks. Over the past five years, I've thrived in roles ranging from DevOps and Full-Stack to Platform and Big Data Engineering.

When I'm not diving into data, you can find me challenging gravity with bouldering, centering my mind through yoga, or strategizing my next chess move.

I am a Data Scientist and AI Engineer at IBM, where I work on machine learning systems and applied AI in production environments. My day-to-day work focuses on building, deploying, and evaluating ML models, while also exploring emerging computational approaches that challenge classical assumptions.

Alongside classical machine learning, I work with quantum computing and Quantum Machine Learning, with an emphasis on practical experimentation rather than theory alone. I have delivered a hands-on quantum computing workshop at IBM, introducing quantum concepts through runnable code and real examples. Using Qiskit, I design and test hybrid quantum–classical workflows, compare them with classical baselines, and analyze the effects of noise, limited qubit counts, and current hardware constraints.

Egidijus Pilypas is Co-founder and Product Director at Exacaster. He has been working with AI and machine learning for over 15 years, spanning telecom, retail, finance, and utilities - long before it became a buzzword. His focus has always been the hard end of the work: the messy data, the legacy systems, the delivery challenges that others avoid.
At PyCon Lithuania 2026, Egidijus will share hands-on lessons from using AI to tackle exactly those kinds of challenges, and why the toughest projects might now be the most interesting ones.

I’m a data engineer who builds tools, systems, and platforms — and enjoys watching them come alive brick by brick. I started as a data analyst, fell in love with Python, and gradually shifted from thinking in tools to thinking in systems and outcomes. I care deeply about automation, observability, and how all the moving parts fit together. Most of what I’ve learned comes from building things in production, fixing what didn’t work, and understanding code beyond the surface.

I lead Engineering at StellarGlyph, a Data and AI agency. We act as an interim/fractional data team and are passionate about helping clients through building modern data and AI platforms.

With a background in mechanical engineering and have worked across a range of sectors including sustainability, energy, property, construction and architecture. I am an engineer at heart and love building.

Raised in Nashville, Tennessee, USA, I have bounced around the world, finally settling in Hamburg, Germany. My professional background reflects my vagabond nature. I taught English in Asia, Latin America, and online (full-time remote work before Covid!), worked in adventure tourism in Appalachia (USA) and Chile, and did my masters in Economics in Hamburg. Somewhere along the way, I gathered a few stories and soft skills.

I met Python during my masters, but stuck with Matlab through the my PhD coursework, until I decided that academia is not my forever home. Currently I am occupying myself with ensemble methods such as XGBoost, as well as expanding into computer vision with PyTorch and toying with more advanced data visualizations. Naturally, NumPy will always hold a special place in my heart, along with the Cython package to sample everything a Bayesian needs.

I'm a Head of Engineering at CoinGate, a crypto payments fintech based in Vilnius. In my experience I've been in various roles: starting as a developer and even testing myself in C level role. I'm most energized when a technical team and a product team stop being two separate things and start building as one.
Outside of work, I organize VilniusPy — local Python meetups where developers meet, chat, and share what they're actually working on. I also speak at conferences, because the best way to keep learning is to put your thinking in front of a room.

I have been a backend developer for 4 years, working primarily with Python and Django. I enjoy sharing what I’ve learned at previous PyCon talks and through writing on Medium, helping others improve their coding and AI skills.

Hello World, I'm Özge Çinko! 👋

I'm a computer engineer who finds inspiration at the intersection of curiosity and technology. Currently building the future as an AI Engineer at ING.

For me, engineering is a creative craft - turning data into narratives and emotions into visual experiences. I am passionate about making technology more human-centric and purposeful.

When I'm not coding, I'm usually writing, traveling, or chasing the thrill of learning something new.

I am a software and data engineer with a passion for open-source. I build data tools and pipelines for KAYAK. On my spare time I create apps that I have been always passionate about.

I like reading and writing. At some point I wish I did not know how to code and could dedicate my time to writing purely. However, I am drawn by the power of code and computers so strongly, that I cannot quit it.

One of the best things this year for me is showing up to kettle bell exercises every day.

I am from Lithuania but for more than 4 years now based in Berlin.
