Yevhenii Kryshtal, Senior Software Engineer: Resilience, Ownership, and the Human Side of Ad-Tech

The Origin Story

“I learned web development by downloading video tutorials at my aunt’s place because I didn’t have internet at home. I studied completely offline like this for about eight months.”

My path into engineering was anything but a straight line. It actually started with failure: I didn’t get the necessary score to enter a technical university, which had been my dream since school. I compromised and went to a technical college, but my time there ended quickly after one year when the occupation of my city began. In the aftermath, very few people were left who wanted to study at a university, but my drive hadn’t changed. I applied again, succeeded, and began studying Computer Engineering.

Studying at the institute I realized, being an engineer is not simple, you have to find your specific niche. For me, that was web technologies. Because I didn’t have internet at home, I would download tutorials at my aunt’s house and study them offline. Eventually, I found classmates who were also practicing web development, and we banded together to solve tasks. But by my third year of university, I landed my first part-time job at a web studio, and my engineering career officially began. Before I shifted my entire focus to my professional development, I was also deeply involved in sports and spent seven years doing folk dancing.

Professional Impact & The GlobalLogic Journey 

My early career was a baptism by fire. I spent a year at a web studio, where I made my first contribution to a popular open-source project, followed by two intense years as the sole web developer at a startup. When I finally joined GlobalLogic, I felt a profound sense of relief. Everything felt mature and professional, overtime were non-existent, and my interest in development and growth skyrocketed. I even turned down an offer in mobile development because I knew GlobalLogic was the right place for me.

Today, I am a Senior Software Engineer working on a major ad-tech project. My team heavily focuses on UI/UX, introducing new standards across the project using a stable stack of React, TypeScript, RTK Query, and Ant Design.

Behind the code, the true business impact of our project is about building an efficient digital ecosystem. We are working to remove the chaos from advertising. We take something that is often viewed as “noise and an irritant” and transform it into a finely tuned tool that successfully funds modern culture and media.

The Crucible: Taking Absolute Ownership 

Throughout my career, I have faced technical roadblocks that required a “race against the clock” mentality, and they taught me exactly what kind of engineer I wanted to be.

In my first job, I accidentally crashed production and blocked the purchase functionality. It was Friday, the end of the working day, and my Team Lead was unhappy. He told me to step aside so he could fix it himself. I refused to let him do it. I knew the mistake better than anyone, and I told him I would finish it myself. I took absolute ownership, and in the end, everything worked out perfectly.

That grit carried over into my startup days, spending weeks buried in Chrome DevTools to optimize SEO and page load speeds by myself, and it serves me well at GlobalLogic today. When I was tasked with rewriting a legacy system built on CoffeeScript and jQuery that contained a chart with incredibly heavy calculations, I spent five solid days just debugging through breakpoints to understand how the values changed. You cannot be intimidated by the code, you have to conquer it.

Achievements & The Drive to Learn 

I am lucky to be surrounded by a great team where the vibe is highly collaborative, we are always giving hints and suggesting where things can be improved.

To keep myself updated and speed up my workflow, I constantly experiment with new engineering tools. I recently switched to the Neovim text editor and have been exploring split keyboards and productivity setups. More importantly, I actively contribute back to the community. I have successfully submitted multiple Pull Requests to Ant Design, a massively popular open-source project. Looking ahead, I plan to continue expanding my technical boundaries, specifically moving deeper into the DevOps direction.
