Ever seen a code base where understanding a simple method meant jumping through tangled class hierarchies? We all have! And while "Favor composition over inheritance!" is almost as old as object-oriented programming, strictly avoiding all types of subclassing leads to verbose, un-Pythonic code. So, what to do? The discussion on composition vs. inheritance is so frustrating because far-reaching design decisions like this can only be made with the ecosystem in mind – and because there's more than one type of subclassing! Let's take a dogma-free stroll through the types of subclassing through a Pythonic lens and untangle some patterns and trade-offs together. By the end, you'll be more confident in deciding when subclassing will make your code more Pythonic and when composition will improve its clarity.

The current architecture of Prom.ua is built on microservices and GraphQL API, but it was not always like that. In this talk, I'll tell you how far we've come and how we've made using graphs in a microservice architecture convenient and simple. I will talk about the problems we faced and how we overcame them, made our development process more accessible, deployments faster, and the remains of the monolith less loaded.

ETL stands for extract, transform, load. It's a process that combines data from different sources into a single repository for further processing, analysis, and utilization. This talk provides an example of how pandas can be used to solve ETL tasks as a stage in the evolution of the data intake component. This involves preliminary validation, filtering, and conversion of data according to a set of business rules and internal representation, with intermediate combination with other sources.

Sharing open feedback can be difficult because it equals much work on yourself. However, feedback needs attention and a special place in the corporate culture. It helps to grow dynamically, build a team of like-minded people and achieve powerful results. In the presentation, I will talk about: The ability to work with feedback as a soft, solid skill in developing technical specialists. A list of difficulties that prevent quality work with feedback. The 4A Framework is a tool for successful giving and receiving feedback. I will also help specialists learn the following: Form constructive feedback and understand how and when to give it. Work analytically with the received feedback. Feel free to share your thoughts and be heard.

This talk will reveal four destructive communication patterns that can undermine team spirit, reduce productivity and cause conflict, and offer effective strategies for neutralizing them. Let's start with exciting storytelling about a fictional team of developers working on Scrum. You will learn about situations that their team member noticed during team meetings. Next, we will analyze "The Gottman Four Horsemen" model, which describes the four "horsemen of the apocalypse" of work relationships: criticism, defensiveness, contempt, and stonewalling. For each of these patterns, specific "antidotes" will be offered that allow you to build healthier and more productive relationships in the team. Finally, we'll look at why this topic is critical to team productivity, drawing on Google's "Project Aristotle" research. Special attention will be paid to the concept of psychological safety, which is a key factor in the success of high-performance teams. This talk will not only provide valuable insights and tools for improving communication and management in Tech teams, but will also help each member better understand their own contribution to the overall success of the team.

We are all living in exceptionally turbulent times. Ukrainians are facing numerous crises and challenges, ranging from war to lay-offs. Work provides us with a sense of stability, which many of us deeply value and strive to maintain.

During our discussion, we will cover: - The factors that contribute to burnout; - How to identify it; - Short-term strategies for addressing it; - Long-term approaches to finding fulfillment and satisfaction in our work; I will also share my personal experiences and insights, as well as those of my colleagues in the IT field. - Burnout - Stress

As you grow in experience as a tech specialist and close the needs of Maslow's hierarchy, you realize that you can help beginners in your specialization. But how to do it effectively? Where to look for future mentees? How to avoid mistakes that demotivate both sides? And, in general, how can you benefit from investing your time in the success of a mentee? I'll discuss this based on my 1.5 years of experience mentoring beginners. It will be useful for professionals with at least six months of experience in IT and a willingness to share their knowledge with the community.

Historically, Ukrainians are not good at presenting themselves (read: selling) because they are not self-confident. But we were never taught to be confident or to understand our strengths, moreover to pitch ourselves well in 3 minutes at an interview. Therefore, my task is to teach you in a few minutes how to: Create your personal pitch correctly (sales points, structure) Understand, depending on the type of company, what managers want to hear about you at the interview Be able to package irrelevant or no experience Understand your strengths Create an example of a personal pitch No, there will be no information here on how to get more $ at the interview, but it's not sure 😂

Imposter syndrome is a psychological phenomenon that most of us suffer from to one degree or another. I'm no exception and have faced this for most of my IT career, which has been around 10 years. I did not immediately understand that the impostor syndrome is one of the biggest blockers for my personal and career development. When I understood it, I gradually started, with small and large steps, fighting with a syndrome in all available ways. In my talk, I will share my story and how it helped me grow from an ordinary developer to a team leader and, eventually, the leader of the entire department.

I would like to share a little story with you about how we started testing our Helm charts, why we did it, and were the outcomes. Our journey went from no testing to snapshot testing with Terratest and then from Terratest to more granular approach towards the validation of the configuration. I would like to show our journey to you as well as the tools we met in the process and the lessons we learned.
