Attacking Toughest and Messiest Tech Challenges with AI
Speaker
Egidijus Pilypas
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.
Abstract
Legacy migrations, tangled integrations, undocumented business logic – every team has that category of work nobody wants to touch. This talk shares practical lessons from using AI to tackle exactly those challenges. Through the example of a real IT system migration – normally a 2–4 year project – we will show how AI can compress the timeline to weeks, reduce the pain, and even make it fun.
Description
Every engineering team has that category of work nobody wants to touch: legacy migrations, tangled integrations, undocumented business logic, and giant system changes full of risk, ambiguity, and manual effort.
Egidijus will share practical lessons from using AI to tackle exactly those kinds of challenges. Through the example of migrating from one IT system to another, a project that would normally take 2–4 years, he will explore how AI can help compress the timeline into weeks, reduce the pain, and also get some fun.
