Dmytro Zelenetskyi's CV

Currently, I’m part of the big and experienced family at IKEA, where the scale of the challenges is huge. It’s a fantastic opportunity to use everything I’ve learned to help solve complex problems in a large, well-established organization.

I joined a fast-growing startup for a year and a half, where we were expanding all over the world. I focused on solving some really tricky but crucial problems, especially around how the shopping cart worked. It was a high-pressure environment, but seeing the impact of our work was really rewarding.

I was part of a team tackling the challenge of making big e-commerce websites load super fast. We used Agile methods, which meant working in a flexible and collaborative way to get great results. I moved up to become a Tech Lead and a Team Lead, which involved interviewing new people, mentoring the team, and helping to shape the products we were building.

A year leading a project to build a fundraising platform for school kids was a big step in terms of managing people and projects. My team and I built several connected microservices to make sure the system was secure and reliable for donation campaigns. We also worked closely with the stakeholders to review the system and figure out how to increase the conversion and the core metrics – and we succeeded!

I focused on building REST APIs, working closely with the mobile team on an app for personal safety and health. This job also involved talking to clients in their offices, which helped me understand what they really needed and how to bridge the gap between tech and business.

For four years, I broadened my tech skills. I worked on all sorts of websites and online stores, which meant getting deep into both how things look (front-end) and how they work behind the scenes (back-end). At the same time, I helped set up infrastructure using Ubuntu and various cloud services, which taught me a lot about how to run and manage systems (DevOps). I also kept the existing Android app running smoothly and wrote handy scripts in Ruby to automate tasks and make things more efficient – something I’ve always been keen on.

My software development career kicked off with Java, where for three years I built web services using GWT and developed some of the very first Android apps. This early stage gave me a solid grounding in how clients and servers talk to each other and what mobile development was like right at the beginning.
