Vladyslav Sidenko

I’m a software engineer who turns business needs into products that really ship—across web and mobile, with focus on fintech and SaaS. I care deeply about architecture, because good foundations make delivery faster and quality easier to maintain.

In my recent role as a Senior Software Engineer, I’ve worked full-time from Dec 2022 to Mar 2026, continuing to lead product-focused engineering efforts. Before that, I was a Senior Software Engineer at Zendesk from Mar 2021 to Dec 2022, building and refining frontend systems in a real-world customer environment.

Earlier in my career, I spent time as a Middle Frontend Engineer at Nord Security (Nov 2019 to Mar 2021) and as a Frontend Developer at upwork (Jun 2019 to Nov 2019). Those experiences shaped how I think about UI engineering end-to-end: delivering value quickly while keeping the codebase maintainable.

I bring a modern stack—React.js, React Native, Next.js, and Node.js—and I use AI to work faster without losing quality. I also connect my technical work to my background in Artificial Intelligence, so I’m comfortable applying practical AI where it helps teams move with confidence.
