On my day-to-day work, I design, build and maintain big enterprise systems and data pipelines. On my spare time, I research new and interesting technologies, mostly related to functional programming, data engineering and machine learning, and then I try to make that somehow leak into my day to day work ūüėČ

Day 2 - 11th Dec 10:30-11:20 Hall 3.2 #J2D Novice Novice

At some point in your career as a developer, you will inevitably end up maintaining a system that you didn’t write, and which you don’t know much about. What are your options? Are there tools and techniques that can make you work easier? Yes, there are! In this talk I’ll go over different approaches that will improve your experience dealing with a legacy system, and also, a set of recommendations for preventing future systems becoming legacy.
